Wine glossary

Every term Rankquant uses in wine normalization, reviews, and methodology. 50+ entries covering scoring scales, grapes, regions, classifications, winemaking, faults, and tasting vocabulary. Each entry exposes schema.org/DefinedTerm structured data.

Parker 100-point scale: A 100-point wine rating scale introduced by Robert Parker in 1978. Nominal range 50–100; effective range 85–100 (wines below 85 are rarely written up). The most widely-used professional wine scoring scale, now continued under Vinous/Antonio Galloni.
Wine Spectator (WS) score: 100-point rating from Wine Spectator magazine, administered by a staff of professional tasters. Tends to favor structured, ageable, classical styles. Correlates closely with Parker on Bordeaux; diverges on Napa Cabernet and Rhône.
Jancis Robinson 20-point scale: 20-point wine rating scale used by Jancis Robinson MW. Nominal range 12–20, effective range 14–20. More conservative than 100-point scales — a 17 is a strong wine, 19+ rare. Rankquant rescales by ×5 for aggregation.
Decanter points: 100-point scale from Decanter magazine, administered by panel tastings with international expert reviewers. Cleaner signal for emerging regions than the US-centric Wine Spectator.
James Suckling score: 100-point rating from James Suckling. Prolific coverage; known to be slightly more generous than Wine Spectator or Parker. Rankquant weights it 7 versus 10 for WS/WA to offset inflation.
Jeb Dunnuck score: 100-point rating from Jeb Dunnuck's independent publication (formerly of Wine Advocate). Growing credibility; coverage focused on Rhône, Napa, Washington, and Bordeaux.
Vivino score: A 1–5 star crowd-rating from the Vivino app. Largest wine-rating user base globally, averaging around 3.8 across the catalog. Rankquant rescales by ×20 and weights at 2 (vs 10 for professional sources).
CellarTracker score: 100-point crowd rating from CellarTracker, an enthusiast wine-cellar-management platform. Lower volume than Vivino but higher per-review quality; commonly used by collectors. Rankquant weights at 3.
Cabernet Sauvignon: The dominant red grape of Bordeaux and Napa Valley. Known for tannin, structure, black-fruit character, and cellar-worthiness. Receives the highest average professional scores in US wine ratings.
Chardonnay: The most-planted white grape worldwide. Takes on dramatically different character from Burgundy (mineral, restrained) to California (tropical, buttery). Stylistic variation matters for peer-set normalization.
Pinot Noir: A delicate red grape famously difficult to grow; dominant in Burgundy, also significant in Oregon and New Zealand. Light-bodied, complex, terroir-sensitive.
Syrah / Shiraz: A full-bodied red grape known as Syrah in the Rhône and as Shiraz in Australia. Dark fruit, black pepper, sometimes smoky/meaty. Two naming conventions; same grape.
Riesling: An aromatic white grape, typically high-acid, ranging from bone-dry (Austria, Alsace) to intensely sweet (German TBA). Often undervalued in US markets despite high critical scores.
Sangiovese: The dominant red grape of central Italy — Chianti, Brunello di Montalcino, Vino Nobile di Montepulciano. High-acid, cherry-forward, food-wine character.
Nebbiolo: The red grape of Barolo and Barbaresco (Piedmont, Italy). Aromatic (rose, tar), high-acid, intensely tannic young; slow-evolving. One of the world's most age-worthy grapes.
Tempranillo: The principal red grape of Spain, especially Rioja and Ribera del Duero. Medium-to-full body, vanilla-oaked traditions, long aging potential in the Gran Reserva category.
Bordeaux: The classic French red-wine region. Left Bank (Médoc, Pauillac, Margaux) produces Cabernet-dominant blends; Right Bank (Saint-Émilion, Pomerol) produces Merlot-dominant blends. Home of the 1855 Classification.
Burgundy: French wine region producing almost exclusively Pinot Noir (red) and Chardonnay (white). Organized by commune and climat; a single village can house dozens of wines with different peer sets.
Napa Valley: California wine region, dominant US producer of premium Cabernet Sauvignon. AVA (American Viticultural Area) subdivisions include Oakville, Rutherford, Stag's Leap, Howell Mountain. Significant variation in scoring by sub-AVA.
Piedmont: Northwest Italian wine region producing Barolo, Barbaresco (both Nebbiolo), and Barbera. One of the most age-worthy and critically-acclaimed regions in Italy.
Tuscany: Central Italian wine region producing Chianti, Brunello di Montalcino, Super Tuscans, and Vino Nobile di Montepulciano. Sangiovese-dominant with some international-variety blends.
Rhône Valley: French wine region split into Northern Rhône (Syrah-dominant: Côte-Rôtie, Hermitage) and Southern Rhône (GSM blends: Châteauneuf-du-Pape, Gigondas, Côtes du Rhône). Parker-era Wine Advocate famously championed Rhône producers.
Champagne: French region producing sparkling wine by the traditional method (méthode champenoise / méthode traditionnelle). Named producers (NM) dominate volume; grower-producers (RM) increasingly trendy. Grapes: Chardonnay, Pinot Noir, Pinot Meunier.
Mosel: German wine region on the Mosel River. Produces some of the world's highest-rated Rieslings — from bone-dry Trocken to intensely sweet Trockenbeerenauslese.
1855 Classification: The original Bordeaux classification, commissioned for the 1855 Paris Exhibition, ranking 61 Médoc estates in five tiers (First Growth through Fifth Growth). Largely unchanged since 1855; effectively immutable.
First Growth (Premier Cru): The top tier of the 1855 Bordeaux classification: Châteaux Lafite, Latour, Margaux, Haut-Brion, and (added 1973) Mouton-Rothschild. The most expensive and highest-average-scored wines in the French classification system.
Grand Cru: The top classification level in Burgundy and Alsace, denoting a specific vineyard rather than a producer. A Grand Cru vineyard in Burgundy (e.g. Montrachet, Chambertin) produces the region's most prestigious — and priciest — wines.
Premier Cru: The second-highest classification in Burgundy (between Village and Grand Cru) and Champagne. Denotes a specific vineyard of recognized quality.
AVA (American Viticultural Area): A US-designated wine-growing region (e.g. Napa Valley, Russian River Valley, Paso Robles). Minimum 85% of the wine's grapes must come from the AVA for the label to use its name.
Appellation d'Origine Contrôlée (AOC): The French wine-region classification system. A specific AOC (e.g. Chablis, Châteauneuf-du-Pape) dictates permitted grapes, yields, winemaking practices, and labeling.
DOC / DOCG: Italian wine classifications. Denominazione di Origine Controllata (DOC) denotes regulated origin and quality; DOCG (Garantita) is a higher tier with more stringent rules. Brunello di Montalcino, Barolo, Chianti Classico are DOCG.
Vintage: The year a wine's grapes were harvested. Weather variation across vintages creates dramatic quality differences in wine-growing regions — a 2018 Bordeaux is a different wine from a 2021 Bordeaux. Rankquant uses vintage (± 1 year) as a peer-set dimension.
Terroir: The combination of soil, microclimate, elevation, and vineyard-management practices that gives a wine its distinctive character. Central to Old World wine identity.
Old World: Traditional European wine-producing countries — France, Italy, Spain, Germany, Portugal, Austria. Wines typically more restrained, terroir-focused, regionally labeled rather than varietally labeled.
New World: Non-European wine-producing countries — US, Australia, New Zealand, Chile, Argentina, South Africa. Wines typically more fruit-forward, varietally labeled, sometimes higher alcohol.
Natural wine: A loose category of wines made with minimal intervention — often unfiltered, unfined, with native yeasts and minimal sulfite addition. Rankquant handles natural wines as a subset of their varietal/region peer set, not as a separate category (most don't have professional score coverage).
Oak aging: The practice of aging wine in oak barrels. American oak gives vanilla/coconut notes; French oak gives toast/spice. Heavily oaked wines often receive higher early-drink scores but risk fatigue by vintage 10.
Malolactic fermentation: A secondary fermentation that converts tart malic acid to softer lactic acid, rounding mouthfeel. Common in Chardonnay and virtually universal in red wine. Absence is a stylistic choice (e.g. some Chablis, some Italian whites).
Wine-Searcher: A commercial database aggregating retail prices across ~100,000 wine retailers globally. Rankquant uses Wine-Searcher data (where licensed) for the retailer matrix in affiliate-routing decisions.
Allocation: A structured release system used by high-demand producers (First Growths, cult Napa Cabernets). Retailers and collectors receive a pre-agreed bottle count; resale markets form around over/under-demand.
Négociant: A French wine merchant who buys grapes or finished wine from growers and bottles under their own name. Louis Jadot, Bouchard Père et Fils, Jean-Claude Boisset are major négociants.
Futures / en primeur: Pre-release wine sales, typically for Bordeaux in the spring after the vintage. Buyers commit to purchase before the wine is bottled, usually at a discount but with substantial price-movement risk.
Cork taint: A wine flaw caused by TCA (2,4,6-trichloroanisole), imparting a musty, wet-cardboard aroma. Affects ~1–3% of cork-closure wines. Major driver of screwcap adoption in New Zealand and Australia.
Brettanomyces: A yeast strain that produces barnyard / Band-Aid / horse-blanket aromas in red wine. Some classic French producers embrace low-level "brett" as a stylistic signature; high levels are a flaw.
Oxidation: Exposure to oxygen causing wine to brown, lose fruit, and develop flat or bruised-apple notes. A progressive flaw in poorly-stored wines.
Reduction: A stylistic or fault condition from low oxygen exposure, yielding sulfurous / struck-match aromas. Often blows off with decanting; chronic reduction is a fault.
Value tier: A price band Rankquant uses for peer-set normalization — typically ±20% of a wine's list price. A $20 wine is compared against $16–$24 peers, not against $5 bottles or $100 bottles.
Release price: The price at which a wine is first released by the producer. For collectible wines, the secondary-market price often moves substantially from release price.
Producer premium: The price uplift a wine earns purely from producer reputation, independent of vintage quality. Rankquant's peer-set normalization controls for this — we compare producer X against price-peers, not against producer X's cheaper-wine library.
Body: Perceived weight / fullness of a wine in the mouth. Light-bodied: Pinot Noir, Beaujolais. Medium: Sangiovese, Tempranillo. Full: Cabernet, Syrah, Zinfandel. Correlates roughly with alcohol.
Tannin: The astringent / drying compounds in red wine, sourced from grape skins, seeds, and oak. High-tannin grapes (Cab, Nebbiolo) need age or food to balance.
Acidity: The sour/tart character of a wine, measured by total acidity (TA) and pH. High acidity lifts fruit and aids food pairing; low acidity feels flabby.
Finish: How long the flavor persists after swallowing. Long finishes (30+ seconds) correlate with professional critic scores; short finishes flag simpler wines.
