The Wine Glossary
Every wine word you'll meet — tasting, winemaking, and region terms — defined in one plain-English sentence. 100 terms, no jargon, no gatekeeping.
A
- AcidityThe tart, mouthwatering sensation in wine. Higher acidity makes wine feel fresh; low acidity feels flabby.
- AgingThe time a wine spends developing — in tank, barrel, or bottle. Transforms primary fruit into bouquet and secondary characters.
- Aglianicoal-YAHN-ee-kohA southern Italian red from Campania and Basilicata. High tannin, dark fruit, often called "the Barolo of the south."
- Albariñoal-bah-REEN-yoA high-acid Galician white grape with stone fruit and saline notes. Rías Baixas is its spiritual home.
- Alsaceal-SASSA French region on the German border producing aromatic, often dry whites — Riesling, Gewürztraminer, Pinot Gris dominate.
- Anthocyaninsan-tho-SY-ah-ninsPigment molecules in red grape skins that give red wine its color. Bind with tannin during aging, shifting hue from purple to garnet.
- AromaThe smells of a wine, primarily from the grape itself (primary aromas) and fermentation (secondary aromas).
- Assyrtikoah-SEER-tee-kohGreece's premier white grape, native to Santorini. Vivid acidity, salinity, and stone-fruit notes from volcanic soils.
- AstringencyThe drying, puckering sensation caused by tannins binding to saliva proteins. Most pronounced in young red wines.
B
- BalanceWhen acidity, tannin, alcohol, sugar, and fruit work in harmony — no single element dominates the perception.
- Barberabar-BEAR-ahA high-acid, low-tannin Italian red from Piedmont. Easy-drinking with bright cherry and plum, often compared to lighter Chianti.
- Barolobah-ROH-lohA Piedmontese DOCG made entirely from Nebbiolo. Long-lived, tannic, with rose petal and tar — often called "the king of wines."
- BeaujolaisBO-zho-layA French region just south of Burgundy producing light, fruity reds from Gamay. Cru Beaujolais offers serious quality at moderate prices.
- BlendingCombining wines from different grapes, vineyards, vintages, or barrels to balance and complete the final cuvée.
- BodyThe perceived weight and viscosity of wine in the mouth — light, medium, or full. Driven by alcohol, sugar, glycerol, and extract.
- Bordeauxbor-DOHA French wine region split by the Gironde estuary. Left Bank favors Cabernet; Right Bank favors Merlot. Source of the world's benchmark blends.
- BouquetThe complex aromas that develop in a wine through aging — distinct from primary fruit aromas of youth.
- Brettanomyces (Brett)breh-TAH-no-MY-seesA wild yeast that creates barnyard, Band-Aid, or horse-stable aromas. In small amounts polarizing; in larger amounts a fault.
- BurgundyBUR-gun-deeA French region focused almost entirely on Pinot Noir (red) and Chardonnay (white). Single-vineyard plots define quality hierarchy.
C
- Cabernet FrancCAB-er-nay FRAHNA parent variety of Cabernet Sauvignon. Lighter, herbaceous, often showing graphite and bell pepper. Star of Loire reds.
- Cabernet SauvignonCAB-er-nay SO-vin-yonThe world's most-planted red grape. Full-bodied, high-tannin, with blackcurrant and cedar notes. Cornerstone of Bordeaux blends.
- Carbonic macerationWhole-cluster fermentation under CO₂ — fermentation begins inside intact berries, producing fruity, low-tannin wines. Beaujolais signature.
- Champagnesham-PAYNEA protected French region producing sparkling wine via the traditional method, primarily from Chardonnay, Pinot Noir, and Pinot Meunier.
- Chardonnayshar-doh-NAYThe world's most-planted white grape. Highly malleable — from steely Chablis to oak-aged Napa to crisp blanc de blancs Champagne.
- Chenin BlancSHEN-in BLAHNA versatile high-acid white from the Loire Valley and South Africa. Covers dry, off-dry, sweet, and sparkling styles.
- Chiantikee-AHN-teeThe largest wine zone in Tuscany — Sangiovese-based reds ranging from light table wines to ageworthy Chianti Classico Riserva.
- ComplexityThe number and integration of distinct flavor and aroma layers a wine offers. Often deepens with age.
- Cork taintA wine defect caused by TCA (2,4,6-trichloroanisole) — produces a wet-cardboard, musty smell that mutes fruit. "Corked" is the slang.
- Corkage feeA fee restaurants charge to open and serve wine you brought in. Typically $15-50 per bottle.
- CrushThe breaking of grape skins to release juice. Both the literal step and the seasonal harvest period in wineries.
D

F
- FermentationThe conversion of grape sugar into alcohol and CO₂ by yeast. Primary (alcoholic) fermentation creates wine; secondary creates bubbles or softens acid.
- FiningAdding agents (egg white, bentonite, casein) to bind and remove suspended particles, clarifying the wine before bottling.
- FinishThe flavor and texture that linger after swallowing. A long finish is a hallmark of high-quality wine.
- Fortified wineA wine with grape spirit added during or after fermentation, raising alcohol to 15-22%. Includes Port, Sherry, Madeira.
G
- GamayGAH-mayThe grape of Beaujolais — light, fruity, low tannin. Made memorable by carbonic maceration in cru Beaujolais.
- Gewürztraminerguh-VURTS-trah-mee-nerAn aromatic pink-skinned grape with lychee, rose, and exotic spice. Most expressive in Alsace; often off-dry.
- GlasswareWine-specific glasses with narrow rims that focus aromas and shapes that match wine style. Bowl size affects aeration.
- GlycerolA natural byproduct of fermentation that adds slight sweetness and viscosity to wine. Contributes to "legs" on the glass.
- Grenachegren-AHSHA widely planted red grape — light-colored but high-alcohol, with red fruit, white pepper, and herbal notes. Backbone of Châteauneuf-du-Pape.
- Grüner VeltlinerGROO-ner VELT-lee-nerAustria's signature white grape — peppery, citrusy, with a savory edge. Pairs well with vegetable-forward dishes.
H
I
J
L

N
- Napa ValleyNAP-pahCalifornia's flagship wine region. Cabernet Sauvignon dominates; warm climate produces ripe, full-bodied, often oak-aged reds.
- Natural wineA loosely defined category for wines made with minimal intervention — no additives, native yeast, low or no sulfites.
- Nebbioloneb-bee-OH-loThe grape of Barolo and Barbaresco — high tannin, high acid, complex aromatics of rose, tar, and dried cherry.
- NoseA wine's overall smell — both aroma (primary) and bouquet (developed). Used as in "the nose shows red cherry and tobacco."
O

- Off-dryA wine with a touch of sweetness — between dry and medium-sweet, typically 5-15 g/L of residual sugar.
- Orange wineA white wine made with extended skin contact, taking on amber color and tannic structure. Also called skin-contact white.
- Oxidation (fault)Unwanted exposure to oxygen, browning the wine and stripping fresh fruit. Different from intentional oxidative aging.

- PressingSqueezing juice from grapes — gentle pressing for whites (before fermentation), often delayed for reds (after maceration).
R
- RackingTransferring wine off its lees and sediment into a clean vessel — clarifies the wine and exposes it to controlled oxygen.
- Reduction (fault)Sulfur-compound aromas (rotten egg, struck match, garlic) from low-oxygen winemaking. Often cleared by decanting.
- ReductiveA wine showing struck-match, rubber, or sulfide notes from low-oxygen winemaking. Often blows off after aeration.
- Residual sugarSugar left in the finished wine after fermentation. Measured in grams per liter (g/L). Determines dry-vs-sweet perception.
