Body
Body describes the weight and fullness a wine feels in your mouth. Think of the difference between skim milk (light), whole milk (medium), and cream (full). In wine, body comes mainly from alcohol level and dissolved solids from the grape. A 1–2/5 light-bodied wine feels refreshing and almost watery — think Muscadet or Riesling Kabinett. A 4–5/5 full-bodied wine feels weighty and viscous — think oaked Chardonnay or Viognier. Body is not a quality indicator.
Acidity
Acidity is the crisp, tart quality in wine that makes your mouth water. It comes from naturally occurring acids in grapes — primarily tartaric and malic acid. High-acid wines feel bright and refreshing; low-acid wines feel soft, round, and sometimes flat. Acidity is one of wine's most important structural elements — it provides freshness, makes wine food-friendly, and enables long aging. On this 1–5 scale, 1/5 means very low acidity (think ripe Gewürztraminer — broad and soft), while 5/5 means very high acidity (think Muscadet or Riesling — mouth-wateringly tart).
Dryness / Sweetness
Dryness refers to how much residual sugar remains in the wine after fermentation. Bone dry (1/5) means essentially no residual sugar. Sweet (5/5) retains significant sugar you taste directly. An important distinction: a wine can smell sweet due to ripe fruit aromas while being completely dry on the palate. Riesling is the classic example — intensely aromatic with peach and apricot notes, but many bottles are bone dry. The rating here reflects what you actually taste on your palate, not what you smell.
Oak
Oak influence refers to flavors and texture imparted by aging or fermenting wine in oak barrels. New oak adds the most character — vanilla, toast, coconut, caramel, and baking spice. Older or neutral oak adds less flavor but still oxygenates the wine gently. On this 1–5 scale, 1 means no oak at all (stainless steel or concrete), while 5 means heavily oaked with dominant vanilla and toast. Oak is neither good nor bad — Chablis at 1/5 and a richly oaked Napa Chardonnay at 5/5 are both valid expressions of the same grape.
Alcohol
Alcohol percentage (ABV) comes from yeast converting grape sugar to ethanol during fermentation. On the 1–5 scale: 1 = very low, under 10% ABV (Mosel Riesling Kabinett, Moscato d'Asti); 3 = medium, 12–13.5% (most table wines); 5 = high, above 14.5% (big Californian whites). Alcohol contributes body and warmth — a slight heat at the back of the throat. In hot climates grapes accumulate more sugar and produce higher alcohol. In cool climates they ripen more slowly, producing lighter wines.
Tannin
Tannin is a polyphenol found in grape skins, seeds, and stems — and in oak barrels. It creates the drying, astringent sensation on your gums and inner cheeks, like strong black tea or an unripe banana. Tannin is essentially absent in conventional white wines because the skins are removed immediately after pressing. It becomes significant in orange and skin-contact wines, where juice ferments with the skins for days, weeks, or months. The easiest way to detect it: run your tongue across your gums after a sip — if they feel dry and slightly rough, that's tannin.
Oxidative character
Oxidative character describes intentional exposure to oxygen during winemaking or aging. Small amounts add complexity — nutty, honeyed, sherry-like notes. High oxidation produces walnut, dried apple, marmite, and aged cheese rind flavors. On the 1–5 scale: 1 = fresh and non-oxidative (most conventional whites); 3 = noticeable oxidative notes (many amphora-aged wines); 5 = highly oxidative (Vin Jaune, some Georgian amber wines). The easiest reference point is dry Sherry — if you enjoy Fino or Manzanilla, you'll likely appreciate oxidative wine styles.
Skin contact duration
Skin contact means leaving white grape juice in contact with the grape skins during fermentation, instead of pressing them off immediately. The skins contain color pigment, tannins, and phenolic compounds that transfer to the juice over time. A few hours gives a slight copper tint and added texture with almost no tannin. A few days gives amber color and noticeable grip. Weeks gives deep amber and significant tannin. Months — as in traditional Georgian qvevri or serious Friuli producers — gives deep amber to red-orange color, firm tannin, and oxidative complexity.
Primary / Secondary / Tertiary aromas & tasting
These tiers describe where aromas come from, not their quality. Primary aromas come directly from the grape — fruit, floral, and herbal notes inherent to the variety. Secondary aromas come from fermentation — brioche, cream, butter, and yeasty notes. Tertiary aromas develop from aging in oak or bottle over time: vanilla, toast, petrol, beeswax, honey, mushroom, and dried fruit. For tasting notes, the same framework applies differently: Entry describes first impressions on the palate, Mid-palate describes texture and structure, and Finish describes what lingers — with skin contact and oxidation as the primary source for orange wines rather than oak and age.
Style codes
LW (Light White) — light-bodied, high-acid, refreshing: Muscadet, Picpoul, Albariño. MW (Medium White) — medium-bodied, balanced: Vermentino, Grüner Veltliner, Falanghina. FW (Full White) — full-bodied, often oaked: Chardonnay, Viognier, Sémillon. AW (Aromatic White) — defined by intense floral or spice aromatics: Gewürztraminer, Muscat, Torrontés. DS (Dessert) — significant residual sugar: Sauternes, Eiswein, Tokaji Aszú. SP (Sparkling) — marks styles that are typically sparkling. OW (Orange / Skin-contact) — made with extended skin maceration. A wine can carry multiple codes — Riesling is both LW and DS because it spans dry and dessert styles.
Quality, Value, and Upside
Quality ceiling (1–5) is the absolute best a grape can achieve in its finest regions — a 5 means world-class potential. Value score (1–5) measures how much quality you get relative to price — QPR. A wine can score 5/5 quality but 2/5 value if the best bottles cost hundreds. Conversely, 3/5 quality with 5/5 value means reliable excellence at $12–18. Price score (1–5) reflects affordability — 5 means very affordable, 1 means expensive. Upside (1–5) measures aging potential — how much better the wine can get with cellar time. Peak auction and aged-bottle prices appear on select cards where the ceiling is historically significant — not every card has this, only where it meaningfully changes the story.
QPR — Quality-to-Price Ratio
How much quality you get for what you spend. A wine with high QPR delivers complexity and enjoyment well above what its price would suggest — a $20 bottle that drinks like a $50 bottle. A low QPR wine is technically good but overpriced relative to what else you could buy for the same money. Most of this tool's value recommendations are built around QPR.
Natural wine
Natural wine has no single legal definition, but generally means: grapes grown organically or biodynamically, fermented with only ambient wild yeast, little or no added sulfites, and no additives like commercial tannins or enzymes. Minimal intervention means the winemaker interferes as little as possible — no heavy filtering or fining, no acid or sugar adjustment. Results can be more complex and alive — or more variable. Natural wines are often cloudy, occasionally slightly fizzy from residual CO₂, and can show unusual flavors from wild fermentation. Most serious orange wine producers work in a natural or low-intervention style.
Wine color — how it's made
Almost all white wines are made from white (green) grapes with no skin contact — the juice is pressed off the skins immediately and fermented alone. Almost all orange wines are made from white grapes with extended skin contact — the skins stay in contact with the juice for days, weeks, or months, giving the wine its amber color, tannin, and texture. Almost all rosé wines are made from red (black) grapes with brief skin contact — a few hours to a day or two — just enough to extract pink color without full red wine tannin. Almost all red wines are made from red grapes with full skin contact throughout fermentation, extracting the deep color, tannin, and structure that define red wine. The grape skin is where color, tannin, and many aromatic compounds live — how long the juice touches the skin is the single most important variable in determining what color and style of wine results.
Standard winemaking — how most wine is made
Most wine follows the same basic arc: grapes are harvested, crushed, and fermented — yeast converts grape sugars into alcohol and CO₂. For white wine, the juice is pressed off the skins before fermentation so it ferments as clear liquid. For red wine, the skins stay in contact with the juice during fermentation, extracting color, tannin, and flavor compounds. After fermentation, wine may be aged in oak barrels (which adds flavor and allows slow oxygenation), stainless steel tanks (which preserves fresh fruit), or concrete/amphora (neutral, with slight oxidation). It's then filtered, stabilized, and bottled. Variations on this template — how long skin contact lasts, what vessel is used for aging, whether malolactic fermentation is allowed — are what create the enormous variety of wine styles from the same basic process.
Carbonic maceration
A winemaking technique where whole, uncrushed grapes are placed in a sealed tank filled with CO₂. Fermentation begins inside each individual grape berry — an intracellular fermentation — before the grapes are pressed. This produces wines with distinctive aromas of red fruit candy, banana, bubble gum, and kirsch, and with very soft, low tannin — because the grape skins never fully rupture and macerate in the traditional sense. Beaujolais Nouveau and many Beaujolais Villages wines use full carbonic maceration, which is why they taste so different from the Beaujolais Crus (which use semi-carbonic or traditional maceration). Semi-carbonic maceration (also called semi-carbonic or Beaujolais method) is the most common version: whole clusters are loaded into a tank, the bottom layer of grapes gets crushed under the weight and ferments traditionally, while the top layers undergo intracellular fermentation. Most Beaujolais Crus use this method. Grapes commonly made this way: Gamay (Beaujolais), Grenache (some southern Rhône and Spanish natural wine), Carignan (Languedoc natural wine), and increasingly used by natural wine producers on almost any variety.
Malolactic fermentation (MLF)
A secondary process — technically a bacterial conversion, not a true fermentation — where sharp malic acid (the acid in green apples) is converted into softer lactic acid (the acid in milk). Almost all red wines go through MLF. For white wines, it's a stylistic choice: blocking MLF (common for Riesling, Sauvignon Blanc) preserves crisp, zippy acidity; allowing MLF (common for Chardonnay, Viognier) adds a creamy, buttery texture and softens the wine. That 'buttery Chardonnay' character is almost entirely MLF. Winemakers who want to avoid it add sulfur dioxide early or keep the wine cold.
Wild / native yeast fermentation
Commercial yeast packets are inoculated into most wine to ensure predictable, controlled fermentation. Wild fermentation (also called native or spontaneous fermentation) uses only the naturally occurring yeasts present on the grape skins and in the winery environment. This is riskier — fermentation can be slow, incomplete, or produce off-flavors — but proponents argue it produces more complex, site-specific wine. Most natural wines use wild yeast. Most Champagne, paradoxically, uses commercial yeast for the second fermentation to ensure reliable bubble formation, even if the base wine was wild-fermented.
Sparkling — Sweetness Scale
Sparkling wines use a different sweetness scale than still wines, based on grams of residual sugar per liter (g/L): Brut Nature / Zero Dosage (0–3 g/L, bone dry) · Extra Brut (0–6 g/L, very dry) · Brut (0–12 g/L, dry — the most common style) · Extra Dry / Extra Sec (12–17 g/L, off-dry, slightly perceptible sweetness) · Sec / Dry (17–32 g/L, noticeably sweet) · Demi-Sec (32–50 g/L, sweet) · Doux (50+ g/L, very sweet). Confusingly, "Extra Dry" is sweeter than "Brut" — the terminology evolved historically and the logic is not intuitive.
Sparkling — Production Methods
Traditional method (méthode champenoise / méthode classique / Cap Classique): second fermentation happens inside the individual bottle, creating bubbles and autolytic notes (brioche, toast, biscuit) from extended lees contact. Used for Champagne, Cava, Crémant, Franciacorta. Tank method (Charmat / Martinotti): second fermentation in a large pressurised tank rather than individual bottles. Faster, cheaper, preserves fresh fruit aromatics. Used for Prosecco and most Moscato d'Asti. Ancestral method (méthode ancestrale / pét-nat): bottled mid-fermentation so the original fermentation finishes in bottle — one fermentation only, no dosage. Often slightly hazy and lower in alcohol. The oldest sparkling wine method.
Dosage
In traditional method sparkling wine, dosage is the small addition of wine and sugar (the "liqueur d'expédition") added after the dead yeast cells are removed. It determines the final sweetness level of the wine and can also be used to balance acidity or add complexity. Zero dosage means no sugar was added — the wine's sweetness comes entirely from the base wine itself.
Lees Aging
After fermentation, dead yeast cells (lees) settle in the bottle or tank. Aging on lees — especially in traditional method sparkling wines — creates autolytic flavors: brioche, toast, biscuit, and pastry notes. The longer the lees aging, the more complex and toasty the wine. Non-vintage Champagne requires minimum 15 months on lees; vintage Champagne minimum 36 months. Prestige cuvées are often aged 5–10 years on lees before release.
NV (Non-Vintage)
A sparkling wine blended from multiple harvest years to achieve a consistent house style. Most commercial Champagne is NV — the blend maintains the producer's signature character regardless of annual weather variation. Vintage Champagne, by contrast, comes from a single exceptional year and is only made when conditions warrant it. NV is not inferior to vintage — it's a different philosophy.
Appellations & designations
Appellations — what they are
An appellation (called DOC, AOC, DO, etc. depending on country) is a legally defined geographic region with rules governing what grapes can be grown, how the wine is made, and what it can be called. The general principle: stricter appellations have lower yields, stricter grape variety rules, and longer aging requirements — and tend to produce more concentrated, serious wine. Broader appellations (like generic 'Bourgogne' or 'Côtes du Rhône') have fewer rules and wider geographic scope. Learning the hierarchy for key regions tells you a lot about a wine before you taste it.
France — AOC / AOP / IGP / Vin de France
France has two separate hierarchies that are easy to confuse. The national regulatory tier has three levels: AOC / AOP (Appellation d'Origine Contrôlée / Protégée) at the top — the strictest rules on grapes, yields, and winemaking, covering named regions from Champagne to Châteauneuf-du-Pape; IGP (Indication Géographique Protégée) in the middle — broader geography, more flexibility, similar to Italian IGT (Pays d'Oc covering the Languedoc is a major example); and Vin de France at the base — no geographic restriction, grapes can come from anywhere in France, often used by natural wine producers who want freedom from appellation rules. The internal quality hierarchy within AOC regions (Burgundy being the clearest example) adds a second ladder of specificity entirely within AOC: Régionale AOC (e.g. Bourgogne Rouge — anywhere in Burgundy) → Village AOC (e.g. Gevrey-Chambertin — one village) → Premier Cru (a named superior vineyard within a village) → Grand Cru (the highest-classified individual vineyards, standalone appellation). So "AOC" is both the top national tier and the label that appears at every level of the Burgundy internal hierarchy — a Grand Cru and a basic Bourgogne Rouge are both AOC wines, just at vastly different rungs of the internal ladder.
Italy — DOCG / DOC / IGT / DOP
DOCG (Denominazione di Origine Controllata e Garantita): Italy's strictest tier. 'Guaranteed' means government tasting panels must approve every wine. Barolo, Barbaresco, Brunello di Montalcino, Chianti Classico are DOCG. DOC (Denominazione di Origine Controllata): the mid tier, similar to French AOC. Still strict, but not government-tasted. Montepulciano d'Abruzzo, Soave, Barbera d'Asti are DOC. IGT (Indicazione Geografica Tipica): the flexible tier. Many of Italy's greatest wines — the 'Super Tuscans' like Sassicaia and Ornellaia — were historically IGT because they used non-traditional grapes (Cabernet Sauvignon, Merlot) not allowed under DOC rules. Sassicaia now has its own DOC. IGT does not mean lower quality. DOP is the EU umbrella term covering both DOCG and DOC.
Spain — DOCa / DO / IGP / Vino de España
DOCa (Denominación de Origen Calificada): Spain's highest tier. Only two regions qualify: Rioja and Priorat (called DOQ in Catalan). DO (Denominación de Origen): the main quality tier — Ribera del Duero, Rías Baixas, Navarra, and most other named regions are DO. Vino de la Tierra: Spain's equivalent of IGP — broader regional wines with some flexibility. Vino de España: the most basic tier, no geographic restriction. Aging tiers within Rioja (and some other DOs): Joven (no required aging), Crianza (minimum 2 years, 1 in oak), Reserva (minimum 3 years, 1 in oak), Gran Reserva (minimum 5 years, 2 in oak). These aging designations appear on the label and are one of the most useful pieces of information on a Spanish wine bottle.
Germany — Prädikat system (ripeness tiers)
Germany uses a unique classification based on grape ripeness at harvest rather than geography. From driest/lightest to sweetest/richest: Kabinett (lightest, often off-dry, lowest alcohol), Spätlese ('late harvest' — riper, more concentrated, still often dry in modern versions), Auslese ('selected harvest' — rich, sometimes sweet), Beerenauslese / BA (very sweet, botrytis-affected), Trockenbeerenauslese / TBA (extraordinarily sweet and rare — individually selected dried/botrytised berries), Eiswein (ice wine — frozen grapes, intensely sweet). Trocken on a label means dry; Halbtrocken means off-dry — these words override the sweetness implied by the Prädikat tier, as modern producers often make dry Spätlese and Auslese. QbA (Qualitätswein) is the broader category below Prädikat — most everyday German wine. Grosses Gewächs (GG): dry wine from a classified Grand Cru vineyard — the serious dry tier outside the Prädikat system.
Portugal — DOC / DOP / Vinho Regional
DOC (Denominação de Origem Controlada): Portugal's main quality appellation. Douro, Dão, Alentejo, Vinho Verde are all DOC. DOP is the EU equivalent term. Vinho Regional: broader regional wines with more flexibility — similar to IGP. Alentejano and Duriense are major Vinho Regional categories. Port and Madeira have their own DOC designations with strict rules — Port must come from the Douro Valley and be fortified with grape spirit; Madeira must come from the island and go through its distinctive heating process (estufagem).
Austria — DAC / Prädikat
DAC (Districtus Austriae Controllatus): Austria's regional appellation system, introduced in 2003 and still expanding. Each DAC specifies which grape varieties are 'typical' for that region — e.g. Wachau DAC is Grüner Veltliner and Riesling, Mittelburgenland DAC is Blaufränkisch. Wines not fitting the DAC rules are labeled 'Niederösterreich' (or another broader region). Wachau has its own internal tier system: Steinfeder (lightest, under 11.5% ABV), Federspiel (medium, 11.5–12.5%), Smaragd (richest, over 12.5%) — named after local wildlife. Prädikat tiers (Kabinett through TBA) exist in Austria similarly to Germany, mainly for sweet wines from Burgenland.
Greece — PDO / PGI
PDO (Protected Designation of Origin): Greece's top tier, equivalent to AOC/DOC. Santorini, Naoussa, Nemea, Muscat of Samos are PDO. Strict rules on grapes and production within a defined area. PGI (Protected Geographical Indication): the broader tier, equivalent to IGP. More flexibility on varieties and winemaking. Many modern Greek producers use PGI Peloponnese or PGI Macedonia to bottle wines from non-traditional varieties or outside PDO boundaries. The distinction between PDO and PGI in Greece is significant — PDO Nemea (Agiorgitiko) has much stricter rules than a generic PGI Peloponnese red.
Bordeaux — the 1855 Classification
Napoleon III commissioned a classification of Bordeaux wines for the 1855 World Exhibition. The result — which has barely changed since — ranks the top Left Bank châteaux into five growths (crus): Premier Cru (First Growth: Lafite, Latour, Margaux, Mouton Rothschild, Haut-Brion), Deuxième Cru (Second Growth), and so on through Fifth Growth. Being classified — even as a Fifth Growth — means guaranteed prestige and pricing. Wines outside the classification are called Cru Bourgeois (a separate ranking) or unclassified. Saint-Émilion has its own classification, updated periodically, with Premier Grand Cru Classé A (Pétrus, Cheval Blanc, Ausone) at the top. Pomerol has no official classification — Pétrus is simply the most expensive by market consensus.
Burgundy — the Grand Cru / Premier Cru system
Burgundy classifies individual vineyards (called lieux-dits or climats) rather than estates. From broadest to most specific: Régionale (e.g. Bourgogne Rouge — can come from anywhere in Burgundy), Village (e.g. Gevrey-Chambertin — from within one village), Premier Cru (a named superior vineyard within a village — the name appears on the label, e.g. Chambolle-Musigny Les Amoureuses), Grand Cru (the highest-classified vineyards, standalone — e.g. Chambertin, Musigny, Montrachet). There are only 33 Grand Cru vineyards. The same vineyard may be owned by many producers (called négociants or domaines) — the producer matters as much as the classification.
Winemaking terms & producer lingo
Cuvée
French term with no precise English equivalent — literally 'vat', used loosely for any specific batch, blend, or selection. A producer's 'Cuvée Prestige' is simply their premium selection. In Champagne, cuvée specifically means the first and finest press run. 'Vieilles Vignes Cuvée' means old-vine selection. You'll hear it constantly in French wine contexts.
Terroir
The complete natural environment of a vineyard — soil, subsoil, slope, aspect, drainage, and microclimate. The French concept (untranslatable in one English word) holds that place is the primary determinant of wine character. 'Terroir-driven' means the wine prioritizes place over winemaking technique.
Négociant vs. Domaine
A négociant buys grapes or wine from growers and sells under their own label. A domaine grows its own grapes — estate production. In Burgundy, the same vineyard estate-bottled may be three times the price of a négociant version because domaine wines are single-grower and more site-specific. Large négociants (Louis Jadot, Duboeuf) produce large volumes with consistent quality.
Château / Estate
In Bordeaux, château is the producer brand — 'Château Margaux' is a producer, not just an address. Some châteaux are modest buildings; the term implies no architectural grandeur. Mis en bouteille au château/domaine on a label means estate-bottled — the producer controls the entire process from vine to bottle.
Vieilles Vignes
Old vines. No legal definition — producers use it at their discretion, typically 30+ years old, often 50–100+ for serious examples. Old vines produce smaller yields of more concentrated fruit from deeper root systems. A useful quality signal when the producer is reputable.
Élevage
The raising or aging of wine after fermentation and before bottling — everything that happens in barrel, tank, or bottle during maturation. A winemaker's élevage decisions are as important as the fermentation itself. 'Long élevage' means extended aging before release — common for serious Burgundy and Bordeaux.
Sur lie
Aged on the lees (dead yeast cells) after fermentation. Adds creaminess, slight bready character, and preserves freshness. Legally defined and labeled in Muscadet. Common in white Burgundy and Loire Chenin Blanc. In Champagne, lees aging is called élevage sur lattes.
Vendange entière
Whole cluster — entire grape bunches including stems used in fermentation. Common in traditional Burgundy Pinot Noir and Côte-Rôtie Syrah. Stems add tannin structure and spice. 100% whole cluster is traditional for some northern Rhône producers.
Chaptalisation
The legal addition of sugar to grape must before fermentation — to increase alcohol, not sweetness. Common in cooler years in Burgundy, Alsace, and Loire. Non-chapitalisé on a natural wine label signals no added sugar. Acidification (adding tartaric acid) is the inverse process used in warm climates.
Morgoniser
A French verb unique to Beaujolais: the way Morgon Cru develops Burgundy-like complexity with age — from fresh, carbonic-style red fruit to something deeper and more structured. No English equivalent exists for this transformation.
Pét-nat (Pétillant naturel)
Naturally sparkling wine bottled before fermentation is complete, so it finishes in bottle trapping CO₂. The oldest sparkling method — predates Champagne. Characteristically hazy, often slightly sweet, lower alcohol, with a wild edge. Gamay pét-nat from the Loire is the classic expression.
Vendange tardive
Late harvest — grapes picked after normal harvest date, resulting in richer, often sweet wines. A legally defined category in Alsace and Germany (Spätlese and above in the Prädikat system). Alsace vendange tardive can be dry, off-dry, or sweet depending on the producer.
Premier Cru / Grand Cru (context matters)
The same words mean different things in different regions. In Burgundy: Premier Cru is a named superior vineyard; Grand Cru is the highest-classified site (only 33 exist). In Champagne: the terms rate the village, not individual vineyards. In Bordeaux: Premier Cru is the top tier of the 1855 classification. Always read the region first.
