KNOWLEDGE
85 wine terms — from finish to tartaric acid, explained clearly and precisely.
The aftertaste of a wine after swallowing.
The finish refers to the flavor impression that lingers in the mouth and throat after swallowing wine. A long, harmonious finish is considered a sign of high quality. Experts distinguish between short (under 10 seconds), medium, and long finishes (over 30 seconds). In great wines, connoisseurs speak of an 'endless finish'.
The total acid content of a wine — key to freshness and aging potential.
Acidity describes the total acid content of a wine, expressed in g/l tartaric acid. Acid gives wine freshness, structure, and aging potential. Too little acidity tastes flat; too much tastes sharp. In cool regions like the Rheingau and Mosel, natural acidity is a hallmark of Riesling.
Ethanol produced during fermentation, shaping body and warmth of wine.
Alcohol (ethanol) is produced when yeasts ferment grape sugar. It influences body, warmth, and shelf life. Alcohol content is stated in percent by volume (%abv). Light wines have 11–12%, full-bodied reds from warm sites often reach 14–15%. Excessive alcohol feels 'hot' and unbalanced.
A wine with sufficient structure to develop positively through extended cellaring.
An age-worthy wine is one that gains complexity through cellaring. Prerequisites include sufficient acid, tannin, or residual sugar as natural preservatives. Great Rieslings from the Rheingau or Pfalz can age for 20–50 years. Red wines from age-worthy varieties like Cabernet Sauvignon also evolve over decades.
German Prädikat: selectively harvested, fully ripe to overripe grapes.
Auslese is the third Prädikat in German wine law (QmP). Grapes are selectively hand-picked, with unripe or diseased berries sorted out. Minimum ripeness: 83–100 °Oechsle depending on region and variety. Auslese wines are often sweet to off-dry with intense fruit. Noble rot (Botrytis) is possible but not required.
Small 225 l oak barrel from Bordeaux – the international standard for wine aging.
The barrique is a small oak barrel standardized at 225 liters, originating in Bordeaux and now used worldwide. Through intensive wood contact, wine absorbs tannins, vanillin, and toasty notes. New barriques impart more flavor than used ones. Aging typically lasts 6–24 months. In Germany, Pinot Noir producers particularly favor barriques.

Spanish ~520 l Sherry cask – the heart of the Solera system in Jerez.
The bota (also "sherry butt") is the traditional aging cask for Sherry in Jerez de la Frontera. At about 520 liters it's never fully filled – the missing one-sixth ("sobretablas") is part of the oxidative aging that gives Fino, Manzanilla, Amontillado and Oloroso their unique character. Botas are crafted from American oak and reused for centuries. Whisky distilleries today pay premium prices for used bota sherry casks.

Rare German Prädikat from individually selected overripe or botrytised berries.
Beerenauslese (BA) is the fifth Prädikat in German wine law. Individually hand-selected overripe or botrytis-affected berries yield concentrated sweet wines with extraordinary depth. Minimum ripeness: 110–128 °Oechsle depending on variety. BA wines are rarities, produced only in exceptional vintages.
Holistic farming method based on Rudolf Steiner's philosophy, beyond organic.
Biodynamic viticulture is based on Rudolf Steiner's anthroposophy and goes beyond organic farming. It centers on farming by a biodynamic calendar (fruit, flower, root, and leaf days), using preparations from plants, minerals, and animal materials, and strengthening the soil's self-regulating forces. Demeter and Biodyvin are the main certification bodies.
White wine or sparkling wine made exclusively from white grape varieties (mostly Chardonnay).
Blanc de Blancs literally means 'white wine from white grapes.' In the Champagne context, it refers to sparkling wine made exclusively from Chardonnay. These wines are often elegant, mineral, and citrus-driven with good aging potential. The term is also used in other German sparkling wine regions.
Noble rot fungus enabling concentrated sweet wines — basis for TBA and Sauternes.
Botrytis cinerea is a fungus that, under specific conditions (humid mornings, dry afternoons), appears as 'noble rot' and affects grapes positively. The fungus perforates the berry skin, water evaporates, and sugar and aromas concentrate. The result is exceptionally rich sweet wines: Beerenauslese and Trockenbeerenauslese in Germany, Sauternes in France.
Complex fragrance of an aged wine from primary, secondary, and tertiary aromas.
Bouquet refers to the aroma of an aged wine, composed of three aroma categories: primary (variety-typical, e.g. peach in Riesling), secondary (from fermentation, e.g. yeast, butter), and tertiary aromas (from aging, e.g. petrol in Riesling, leather, tobacco). A complex bouquet is a hallmark of great wines.
Dryness level for sparkling wines: maximum 12 g/l residual sugar.
Brut is the most common dosage level for sparkling wine and Champagne. It indicates a residual sugar content of up to 12 g/l (in practice often 6–9 g/l). Below this are Extra Brut (max. 6 g/l) and Brut Nature or Zero Dosage (0–3 g/l). Brut wines taste dry, fresh, and are particularly suited as aperitifs.
Family of grape varieties from Burgundy — Pinot Noir, Pinot Gris, Pinot Blanc.
Burgunder refers to a family of grape varieties originating in the French region of Burgundy. The best-known German representatives are: Spätburgunder (Pinot Noir), Grauburgunder (Pinot Gris), Weißburgunder (Pinot Blanc), and Frühburgunder (Pinot Madeleine). The Pfalz, Rheinhessen, and Rheingau rank among Germany's finest Pinot regions.
The world's most important red grape, originating in Bordeaux, known for blackcurrant.
Cabernet Sauvignon is the world's most widely planted red variety. Typical aromas: blackcurrant, cedarwood, graphite, green pepper. It is characterized by firm tannins and high acidity enabling long aging. Classic regions: Médoc (Bordeaux), Napa Valley, Margaret River (Western Australia). Rarely grown in Germany as the variety needs warm sites.
The world's leading white grape variety — from Chablis to Margaret River.
Chardonnay is the world's most recognized white grape variety. Depending on climate and winemaking, the spectrum ranges from bone-dry, mineral wines (Chablis, Blanc de Blancs) to lush, buttery, oak-driven styles (Napa Valley, Burgundy). In Western Australia (Margaret River), Chardonnay produces elegant, citrus-fresh wines with long development.
French 500–600 l large cask, popular in southern France and the Rhône.
The demi-muid ("half muid", as the muid historically had double the volume) is a French large cask of 500 to 600 liters. It's widespread in southern France (Languedoc, Rhône, Provence) and increasingly used in Germany for Pinot Noir and Riesling. The larger wood mass dampens aroma transfer and emphasizes slow micro-oxidation instead – yielding complex, long-lived wines without overlaying them with vanilla or toast notes.

Pouring wine into a decanter for aeration and separation from sediment.
Decanting involves carefully pouring wine into a carafe. This serves two purposes: with old wines, it separates sediment from the clear wine. With young reds, aeration speeds up opening, softens tannins, and allows aromas to bloom. Tannic wines like young Pinot Noir or Cabernet benefit from 30–120 minutes of decanting time.
Biodynamic certification label following Rudolf Steiner's guidelines.
Demeter is the world's best-known certification mark for biodynamically produced goods. In viticulture, this means: no synthetic pesticides or herbicides, application of biodynamic preparations (e.g. horn manure 500, horn silica 501), farming by the biodynamic calendar, and minimal intervention in the cellar. Demeter wines are considered the epitome of terroir expression.
Natural sediment in wine — tartrate crystals, pigments, proteins.
Deposit refers to the natural sediment that forms in aged wines. This includes tartrate crystals (potassium bitartrate), precipitated pigments (in red wines), and protein flakes. Sediment is a quality indicator showing the wine has not been over-filtered. When serving, the bottle should be stored upright beforehand and the wine decanted.
Pressed from naturally frozen grapes — a rare German specialty.
Eiswein is produced when healthy grapes freeze on the vine and are harvested and pressed immediately at temperatures of at least -7°C. The frozen water remains as ice crystals while the concentrated juice flows out. The result is an extremely rich, sweet wine with high acidity and long aging potential. Minimum ripeness: 110–128 °Oechsle. Good Eiswein vintages are rare.
Harvest quantity per hectare — lower yields often indicate higher quality.
Yield indicates how many hectoliters of wine are produced per hectare of vineyard. In Germany, the maximum for quality wine is 105 hl/ha; in practice, good estates yield 30–60 hl/ha. Lower yields concentrate aromas and structure in each berry. VDP estates often enforce significantly stricter yield limits.
Traditional 1,000 l Mosel cask – the epitome of classical Riesling aging.
The Fuder is the traditional aging cask of the Mosel, Saar and Ruwer. At 1,000 liters it offers minimal wood contact per liter of wine – ideal for Riesling, whose delicate fruit and minerality must not be overshadowed by oak aromas. Fuder are typically built from German or French oak and used over decades, so they barely impart any aromas ("neutral Fuder"). Mosel large-cask culture is UNESCO-worthy: estates like J.J. Prüm, Egon Müller and Fritz Haag age their finest Rieslings exclusively in Fuder.

Elegance and refinement in a wine — the opposite of coarse or massive.
Finesse is a tasting term for elegance, polish, and inner tension in a wine. A wine with finesse combines power and lightness without being imposing. Cool-climate regions like the Rheingau or Mosel typically show more finesse than warm regions. The concept is hard to measure but unmistakable among experienced tasters.
Cellar technique to clarify wine by removing particles.
Filtration involves pressing wine through a filter to remove turbidity, yeasts, or bacteria. Methods range from coarse sheet filtration to membrane and sterile filtration. Heavy filtration can reduce texture and aromatic complexity. Natural wine producers often forgo filtration entirely, which may result in slight haze.
Primary aromas of fruit and berries in wine, variety-typical.
Fruit refers to the primary aromas originating directly from the grape. Each variety has typical fruit aromas: Riesling shows apple, peach, citrus; Pinot Noir shows cherry, strawberry, raspberry; Cabernet Sauvignon shows blackcurrant. Intense fruit is not a sign of sweetness — even dry wines can be fruit-intense.
Biochemical process where yeasts convert sugar into alcohol and CO₂.
Alcoholic fermentation is the core process of winemaking. Yeasts (Saccharomyces cerevisiae or wild yeasts) break down grape sugar into ethanol, CO₂, and heat. Temperature, yeast strain, and oxygen contact significantly influence the outcome. Malolactic fermentation subsequently converts the harsh malic acid into softer lactic acid.
VDP's highest quality tier for dry wines from classified single vineyards.
Großes Gewächs (GG) is the top classification of the Association of German Prädikats Wine Estates (VDP) for dry wines. It corresponds to the VDP.Große Lage level and is produced only from the best classified single vineyards. Minimum requirements include low yields, hand harvesting, and no chaptalization. The GG is traditionally released one year after harvest.
Wine produced exclusively from the estate's own vineyards.
Gutsabfüllung means the wine is made from grapes grown exclusively on the bottling estate's own vineyards. The term is legally protected and guarantees origin-based quality. It is comparable to the French 'Mise en bouteille au Château/Domaine.' In Germany, it is a quality criterion for terroir-oriented estates.
Microorganism that ferments sugar — key to wine's creation.
Yeasts are single-celled fungi (primarily Saccharomyces cerevisiae) that convert grape sugar into alcohol and CO₂. A distinction is made between cultured yeasts (lab-derived) and wild yeasts (naturally present on grapes and in the cellar). Wild yeasts produce more complex, often more variety-typical wines but are harder to control. Yeasts significantly influence aroma, structure, and character.
Unit of measurement for wine: 1 hl = 100 liters = approx. 133 bottles.
Hectoliter (hl) is the common unit of measurement for wine volumes in the wine industry. 1 hectoliter equals 100 liters or approximately 133 standard 0.75l bottles. Vineyard yields are expressed in hl/ha. German quality wines may produce a maximum of 105 hl/ha; VDP vineyards typically yield 40–60 hl/ha.
Wine from a single harvest year, whose character is shaped by the weather.
A vintage wine must contain at least 85% (EU standard) grapes from the stated harvest year. The year's weather significantly shapes acidity, sugar, tannin, and aromas. German vintages vary greatly: excellent years (2015, 2017, 2019, 2021) yield concentrated, long-lived wines; difficult years demand skill in the cellar.
Germany's lightest Prädikat — fresh, elegant, low in alcohol.
Kabinett is the first and lightest of the six German Prädikats (QmP). Kabinett wines come from fully ripe grapes at 67–82 °Oechsle. They are typically light (often 7–9% abv), fresh, and elegant. Riesling Kabinett from the Mosel or Rheingau is considered one of the greatest wine experiences — complex despite minimal weight. The term derives from the 'cabinet' strong room.
Calcareous subsoil — imparts minerality and freshness to wines.
Calcareous soils (chalk, clay-limestone, Keuper) underpin many great wine sites. Limestone retains water, regulates pH, and transmits minerality to the wine. Famous calcareous terroirs: Chablis (Kimmeridgian chalk), Champagne, Sancerre, and parts of the Pfalz and Rheingau. Riesling on limestone often shows precise acidity and cool minerality.
Official ranking of vineyards, estates, or wines by quality criteria.
Wine classifications rank sites or estates by quality. In Germany, the VDP classifies vineyards as Gutswein, Ortswein, VDP.Erste Lage, and VDP.Große Lage. In Burgundy, the hierarchical system runs Grand Cru > Premier Cru > Village > Regional. In Bordeaux, châteaux are classified historically. In Australia, Langton's Classification is the best-known reference.
Long-term weather conditions of a region, decisive for wine character.
A wine region's climate determines which grape varieties thrive and what character wines develop. Types include: continental climate (hot summers, cold winters, large diurnal swings), maritime climate (moderate, humid, ocean-buffered), and Mediterranean climate (warm, dry, mild winters). Western Australia (Margaret River) benefits from cooling oceans; the Rheingau from slate-induced warmth.
Natural closure from cork bark — enables slow aging but carries TCA risk.
Natural corks from cork oak bark (Quercus suber) are the traditional closure for quality wines. Their microporosity allows minimal oxygen exchange and promotes slow aging. Main drawback: cork taint (TCA — 2,4,6-trichloroanisole) can give wines a musty, damp-cellar smell. Alternatives include screw caps and DIAM technical corks.
Demarcated vineyard with specific terroir — from estate wine to Große Lage.
A vineyard site (often Einzellage) is a clearly demarcated vineyard area with uniform terroir of soil, exposure, and microclimate. In Germany, the VDP distinguishes: Großlage (misleading, not a true single site), Einzellage, and the VDP classification (Gutswein, Ortswein, Erste Lage, Große Lage). Famous sites: Rüdesheimer Berg Schlossberg, Forster Jesuitengarten, Pettentaler.
The grape harvest — manual or mechanical, depending on quality standards.
The wine harvest (vendange/harvest) is the high point of the wine year. Machine harvesting is more efficient and cheaper; hand harvesting enables selection and gentle picking. For Prädikat wines (Spätlese, Auslese, BA, TBA), hand harvesting is legally required. The optimal harvest date is crucial: too early yields excess acidity; too late brings alcohol and aromatic poverty.
The harvested grape material, basis for wine quality.
Lesegut refers to the harvested grapes in their entirety before processing. Quality, ripeness, health, and selection of the harvested grapes are decisive for final wine quality. Careful winemakers select in the vineyard and sort on a sorting table afterward. Modern harvests are often transported in small crates (20 kg) to avoid must oxidation.
Contact time of grape juice and skins — extracts color, tannin, aromas.
Maceration is the period during which juice remains in contact with grape skins. In red wines, this extracts pigments (anthocyanins), tannins, and aromas. Duration varies from a few hours to several weeks depending on the desired style. In white wines, brief maceration is common for added texture. Orange wine is produced by extended maceration of white grapes.
Australia's prestigious wine region: Cabernet, Chardonnay, maritime climate.
Margaret River is located in southwestern Western Australia and is considered one of the most significant wine regions in the Southern Hemisphere. The maritime climate (cool oceans on three sides) enables Riesling-like elegance in a warm environment. The hallmarks are world-class Cabernet Sauvignon and Chardonnay. Only 3% of Australian wine production comes from here, but a disproportionate share of top wines.
Salty, stony taste in wine, often associated with slate or limestone.
Minerality describes sensory impressions like slate, wet stones, salt, chalk, or iodine. Scientifically, the direct transfer of soil to wine aroma is debated; the sensation arises from acidity, pH, specific compounds, and aging style. Great Rieslings from slate (Mosel, Saar) are considered the epitome of minerality. Margaret River Chardonnays often show salty-mineral notes.
Unfermented or freshly pressed grape juice, the precursor to wine.
Must (grape must) is the freshly pressed, unfermented grape juice. It contains sugar, acid, water, minerals, aromas, and precursors of aromatic compounds. The measuring instrument for must sugar content is the refractometer (Oechsle scale). Must quality largely determines the final wine product.
Wine with minimal intervention, wild yeasts, no fining, often unfiltered.
Natural wines are produced with minimal cellar intervention. Typical characteristics: wild yeasts instead of cultured yeasts, no added SO₂ (or very little), no fining, no filtration. Natural wines can be slightly hazy or have complex, unusual aromas. The movement originated in France (Loire, Burgundy) and has influenced winemakers worldwide. There is no official certification.
German unit measuring sugar content in grape must.
The Oechsle scale (°Oe) measures the density of grape must, from which sugar content is calculated. It was developed in the 19th century by physicist Christian Ferdinand Oechsle. 1 °Oe corresponds to 1g excess weight per liter of must compared to pure water. Germany's Prädikat categories (Kabinett through TBA) define minimum Oechsle values.
White wine with extended skin contact — tannic, oxidative, amber in color.
Orange wine (amber wine) is a white wine vinified like a red: the juice remains in contact with white grape skins for weeks or months. The result is a tannic, often oxidative drink ranging from amber to orange in color. The style has roots in Georgia (Qvevri tradition) and is experiencing a worldwide renaissance today.
Oxygen's influence on wine — can create faults or become a style.
Oxidation occurs when wine is exposed to oxygen for too long. Faulty oxidation manifests as nutty aromas, sherry-like notes, and browning — unwanted in fresh wines. Controlled oxidation, however, is a deliberate style feature in Sherry (Fino, Amontillado), Madeira, and some natural wines. Antioxidants like SO₂ and fill levels protect against unwanted oxidation.
Burgundian 228 l oak barrel – Burgundy's standard, nearly identical to the barrique.
The pièce is Burgundy's counterpart to the Bordelaise barrique. At 228 liters, it's only three liters larger and has served for centuries as the standard barrel for Pinot Noir and Chardonnay in Burgundy. Top estates like Romanée-Conti, Leflaive and Coche-Dury age their wines exclusively in pièces. Unlike the internationally standardized barrique, pièces traditionally come from various French coopers (tonneliers) whose style shapes the aroma – François Frères, Damy, Cadus, Chassin are most famous.

Portuguese 534–550 l Port aging cask.
The pipe (in Portuguese "pipa") is the traditional aging cask for Port in the Douro valley and in the Vila Nova de Gaia lodges. It holds 534 to 550 liters depending on region and producer. Vintage Ports typically age only 2 years in the pipe before bottling; Tawnies, by contrast, age 10, 20, 30 or 40 years – developing through oxidation toward caramel, nut and dried-fruit aromas. The shipping size "pipa de embarque" at 550 liters was historically optimized for Atlantic transport.

Large 500 l oak cask from overseas tradition – favored by natural wine and cool-climate producers.
The puncheon is a larger oak cask of about 500 liters. Compared to the barrique, the wood-to-wine ratio is lower – yielding subtler oak aromas and more fruit preservation. Puncheons are popular among modern producers in Western Australia (e.g. Margaret River Chardonnay specialists), New Zealand, and increasingly with German natural wine pioneers – as an alternative to the barrique when the producer wants restraint in oak use.

The bubble formation in sparkling wine — fineness and persistence as quality indicators.
Perlage refers to the carbon dioxide bubbles in sparkling wine. Fine, persistent perlage with small bubbles is a quality indicator: it results from extended yeast aging (Méthode Champenoise). Coarse, rapidly rising bubbles result from cheaper production methods (Cuve close). Perlage persistence is measured in minutes.
Measure of acidity: typically 3.0–3.8 in wine, affecting freshness and preservation.
pH measures the concentration of free hydrogen ions — the strength, not the quantity, of acid (unlike titratable acidity). Wine pH ranges from 2.8 (very acidic) to 4.0 (flat). Lower pH promotes microbiological stability and fresh sensations. Malolactic fermentation raises pH. Riesling often has lower pH (3.1–3.4) than full-bodied reds (3.5–3.8).
The 'diva' among red varieties — sensitive, complex, unmistakable. German: Spätburgunder.
Pinot Noir (Spätburgunder) is one of the world's most demanding grape varieties. It is extremely sensitive to terroir and climate. Aromas: cherry, strawberry, raspberry, violet, spice; with age: leather, mushroom, truffle. Classic home: Burgundy (Côte de Nuits). In Germany, the Pfalz, Ahr, and Baden lead. In Western Australia, cooler-site Pinot Noirs show great elegance.
German wine law: six ripeness levels from Kabinett to Trockenbeerenauslese.
Prädikats (Qualitätswein mit Prädikat, QmP) are the highest quality tier in German wine law, designating six ascending ripeness levels: Kabinett, Spätlese, Auslese, Beerenauslese, Eiswein, Trockenbeerenauslese. Each level defines minimum Oechsle values. Chaptalization (adding sugar) is prohibited for Prädikat wines.
Sugar remaining in finished wine after fermentation — determines sweetness.
Residual sugar (RS) is the sugar remaining in wine after fermentation, expressed in g/l. Dry wines contain under 9 g/l (often under 4 g/l), off-dry 9–18 g/l, medium-sweet 18–45 g/l, sweet over 45 g/l. Importantly, perceived sweetness is influenced by acidity — high acidity makes substantial RS taste 'dry' (classic Mosel Riesling).
Prestigious Rhine wine region — home of classic Riesling and great estates.
The Rheingau is one of Germany's most storied wine regions, north of Wiesbaden and Rüdesheim. The unique slate soils, southward-facing Rhine bend, and moderate climate create ideal conditions for Riesling and Pinot Noir. Notable estates: Schloss Johannisberg, Kloster Eberbach, Weingut Robert Weil. VDP sites: Rüdesheimer Berg Schlossberg, Marcobrunn.
Germany's largest wine region — diverse, innovative, strongly growing.
Rheinhessen, bordered by the Rhine to the east and north, at 26,800 ha is Germany's largest wine region. Once known for mass-market wine (Liebfrauenmilch), the region has undergone a quality revolution since the 2000s. Today it leads in Silvaner, innovative Riesling, and Pinot Noir. Key sub-regions: Roter Hang, Wonnegau. VDP sites: Pettentaler, Aulerde.
Germany's great white variety — terroir mirror, long-lived, unmistakable.
Riesling is Germany's most important grape variety and one of the noblest white wines in the world. Typical aromas: apple, peach, citrus, jasmine, petrol (with age). Outstanding feature: the ability to precisely mirror terroir differences. Riesling ages for decades, gaining complexity. Classic regions: Mosel (slate), Rheingau, Pfalz (limestone/basalt). Also growing in Australia.
Wine from co-fermentation of red and white grapes.
A Rotling (not to be confused with Rosé) is produced by co-fermenting red and white grapes together. The best-known Rotling is Schillerwein from Württemberg. Unlike Rosé, which results from brief maceration of red grapes, the blend of varieties is the key aspect for Rotling. Rotlings are a specialty of certain German regions.
Classical 1,200 l large cask of the Rhine and Main – traditional vessel for Rheingau Riesling.
At 1,200 liters, the Stückfass is the largest traditional aging cask in German viticulture and the standard along the Rhine, Main and Rheingau. Like the Mosel Fuder, it enables near-neutral aging of Riesling – at this wood-to-wine ratio, oak aromas barely transfer; instead, wine develops great complexity through slow micro-oxidation and yeast contact. Top estates like Schloss Johannisberg, Robert Weil and Künstler use Stückfass for their top Rieslings. Halbstückfässer (600 l) are a smaller variant.

Aromatic white variety — gooseberry, grass, citrus, smoky spice.
Sauvignon Blanc is an aromatic white variety with an unmistakable profile: gooseberry, nettles, freshly cut grass, citrus to grapefruit, and smoky spice. Classic origins: Sancerre and Pouilly-Fumé (Loire), Marlborough (New Zealand). In Western Australia (Margaret River), elegant, less pungent styles are produced. Often blended with Sémillon.
Slate as vineyard soil — stores heat, imparts minerality.
Slate is a metamorphic rock found in many classic vineyard sites. Its ability to store solar warmth during the day and release it at night is crucial for viticulture in cool regions. Slate wines often show slaty, smoky minerality. Famous slate sites: Mosel, Saar, Nahe, Rüdesheim (Rheingau). Blue, grey, and red slate differ in mineral content.
German quality sparkling wine — with or without origin designation.
Sekt is the German term for quality sparkling wine with at least 3.5 bar of CO₂ pressure. Two main categories: Cuvée-Sekt (from base wines of various regions) and Winzersekt or Crémant-style with protected origin designations. High-quality German sparkling houses (Henkell, Rotkäppchen) and small producers use the Méthode Champenoise (bottle fermentation).
Traditional German white variety — neutrally spiced, terroir-sensitive, strong in Rheinhessen.
Silvaner is one of Germany's oldest grape varieties, most widespread in Franconia and Rheinhessen. Style: understated spice, green herbs, quince, neutral cleanness. Silvaner is less aromatic than Riesling but shows strong site fidelity and terroir sensitivity. On deep loess soils (Rheinhessen), it produces structured, long-lived wines. Great sites: Würzburger Stein, Niersteiner Oelberg.
Sulfur dioxide — universal preservative in wine against oxidation and bacteria.
Sulfur dioxide (SO₂) is the most widely used preservative in viticulture and the cellar. It acts as an antioxidant and antimicrobial, preventing premature oxidation and off-flavors. EU regulations set maximum limits by wine type (e.g. 150 mg/l for dry reds, 200 mg/l for dry whites). Natural wine producers use zero sulfites or very small amounts.
Germany's most important red variety — complex, elegant, world-class in the Pfalz.
Spätburgunder (Pinot Noir) is Germany's most significant red grape. The Pfalz, Baden, and Ahr produce wines of international top quality. Aromas: ripe cherry, wild raspberry, clove, tobacco, and — with age — leather and mushroom. The challenge: Spätburgunder needs cool sites for finesse and reacts sensitively to aging. German Pinot Noirs now rival Burgundy.
Second German Prädikat — late-harvested, fully ripe grapes with pronounced character.
Spätlese is the second Prädikat (QmP) of German wine law. Grapes are harvested at least a week after the regular harvest start, at 76–90 °Oechsle. Spätlese wines can be made dry to off-sweet. Classic are Riesling Spätlesen with their balance of ripeness, sweetness, and animating acidity. Dry Spätlesen (a precursor to Großes Gewächs) are also typical of the Pfalz and Rheingau.
Polyphenolic compounds from skins, seeds, stems — providing structure and astringency.
Tannins are polyphenols derived primarily from berry skins, seeds, and stems as well as from oak barrels. They create the astringent (mouth-drying) sensation. Tannins are essential to the structure and aging potential of red wines. Over time, tannins polymerize and soften (ripe tannins). White wines contain very little tannin.
Totality of soil, climate, topography, and human hand at a vineyard site.
Terroir encompasses all the natural factors shaping a vineyard: soil (minerals, structure, drainage), climate (temperature, rainfall, wind), topography (exposure, slope, altitude), and human vinification. The French concept has been adopted worldwide. Terroir explains why the same winemaker using the same variety from two adjacent sites produces fundamentally different wines.
German taste designation: max. 9 g/l residual sugar or balanced acid and sugar.
'Trocken' (dry) is the German taste designation for dry wines. Legally, a wine is dry if it contains max. 9 g/l residual sugar, or max. 12 g/l if total acidity is no more than 2 g/l below residual sugar (e.g. 11 g/l RS with 10 g/l acidity is permitted). Dry wines have gained significantly in Germany over the past 30 years.
Germany's highest Prädikat — dried botrytised berries, infinite sweetness.
Trockenbeerenauslese (TBA) is the sixth and highest Prädikat in German wine law. From nearly dried, shriveled botrytis berries, wines of extreme concentration and sweetness (often over 500 g/l residual sugar) are produced. Minimum Oechsle: 150–154°. Harvesting is extremely labor-intensive (berry by berry) and yields are minimal. TBA wines are internationally sought-after rarities.
How clearly a wine expresses the characteristics of its variety or origin.
Typicity refers to the degree to which a wine expresses the characteristic features of its grape variety, region, or origin. A typical Riesling shows apple, citrus, and petrol; a typical Pinot Noir shows cherry and earthiness. High typicity is a quality marker for estates prioritizing terroir expression. 'International style' often refers to wines with less typicity, trimmed for mass appeal.
The fifth taste — 'savory-meaty', in wine through yeast extract and age.
Umami (Japanese: 'delicious-savory') is one of the five basic tastes. In wine, umami impressions arise from glutamates, amino acids from yeast lysis (yeast contact during aging), and with age. Champagne and Crémant with extended yeast aging show pronounced umami characteristics. Old red wines also develop a savory depth that goes beyond fruit and tannin.
Association of German Prädikat Wine Estates — union of ~200 of Germany's best estates.
The VDP (Verband Deutscher Prädikatsweingüter) is the most renowned quality association in German viticulture. Founded in 1910, it today comprises around 200 members from all major growing regions. The VDP has introduced its own classification system (Gutswein, Ortswein, Erste Lage, Große Lage) modeled on Burgundy. Member quality is — with exceptions — above average.
Second-highest VDP vineyard classification — comparable to Burgundy's Premier Cru.
VDP.Erste Lage designates the second tier in the VDP classification system. These classified single vineyards have special climatic and pedological properties above Ortswein level but just below Große Lage. Dry Erste Lage wines may carry the Spätlese Prädikat. Erste Lage conceptually corresponds to Premier Cru in Burgundy.
VDP's highest vineyard class — corresponds to Grand Cru in Burgundy, dry (GG) or nobly sweet.
VDP.Große Lage is the highest vineyard category in the VDP system. These sites are historically recognized and show exceptional quality potential. Dry wines from them are called Großes Gewächs (GG); nobly sweet ones retain their Prädikat designation. VDP.Große Lage corresponds to Grand Cru in Burgundy. Famous Große Lagen: Forster Jesuitengarten (Pfalz), Rüdesheimer Berg Rottland (Rheingau), Niersteiner Pettenthal (Rheinhessen).
Addition of tartaric acid for more freshness — common in warm regions.
Acidification is the legal addition of tartaric acid (L-tartaric acid) to wine or must to increase acidity. In warm vintages or hot regions (e.g. parts of Western Australia), natural acidity may be too low. In Germany, acidification and enrichment (chaptalization) may not be performed simultaneously. Opposite: acid reduction through malolactic fermentation (MLF).
The entire winemaking process from must to finished bottle.
Vinification encompasses all cellar steps from grape reception to bottling: harvesting, destemming, crushing, pressing, must clarification, fermentation, aging (barrel, tank, concrete), fining, filtration, and bottling. Every decision (wild vs. cultured yeast, barrique vs. steel, filtration vs. unfined) significantly shapes wine character.
Harvest year — also for outstanding single-vintage Port wines.
Vintage designates the harvest year of a wine. In the Port context, Vintage Port refers to a high-quality, age-worthy Port from an exceptional year, barrel-aged briefly then capable of decades of bottle development. Only in outstanding years is a Vintage Port officially declared (declared vintage). Classic houses: Taylor's, Graham's, Quinta do Noval.
Vine-growing area with vines — the heart of every winery.
The vineyard is the growing area where wine grapes are cultivated. It is defined by location, exposure (south-facing ideal), slope gradient, soil, planting density, and training system. In Germany, steep sites (from 30% gradient) are particularly traditional but labor-intensive. Vineyard management includes: pruning, soil care, plant protection, and green harvesting.
Regulatory framework for wine production, labeling, and quality levels.
Wine law regulates wine production, labeling, and quality categories. In Germany, it distinguishes: Tafelwein, Landwein, Qualitätswein bestimmter Anbaugebiete (QbA), and Qualitätswein mit Prädikat (QmP). EU-wide, regulation 1308/2013 applies. Origin designations (site, village, region) are subject to strict rules. Germany fundamentally reformed its wine law in 2021.
Estate that grows grapes and produces wine — from small producer to Château.
A winery (Domaine, Château, Estate) is a wine production business that controls the entire value chain from vineyard to bottled wine. In Germany, Gutsabfüllung (own grapes only) and Erzeugerabfüllung are legally distinguished. Small family estates dominate the scene; the Rheingau and Pfalz particularly feature historic estates with centuries-old traditions.
Dominant acid in wine grapes — stable, providing freshness and structure.
Tartaric acid (L-tartaric acid) is the most important and stable acid in wine grapes. Unlike malic acid, it is not broken down by malolactic fermentation. Tartaric acid gives wine freshness, structure, and shelf life. At cool temperatures, tartaric acid precipitates as potassium bitartrate (tartrate crystals) — harmless, but sometimes alarming for consumers.
Wine from white or red grapes without skin contact — clear to golden yellow.
White wine is produced from white grapes or — without skin contact — from red grapes (e.g. Blanc de Noirs). Typical aromas: citrus fruits, stone fruit, blossoms, minerals. White wines are usually served at 10–14°C. In Germany, Riesling, Pinot Gris, Silvaner, and Pinot Blanc dominate. Western Australia leads with Chardonnay and Sauvignon Blanc.
