What does terroir mean in wine?

Terroir is the complete natural environment of a vineyard — soil, subsoil, climate, altitude, aspect, and even the microorganisms present. It's the French concept that a wine's character comes primarily from where the grapes are grown, not just what variety they are or how the wine is made. Terroir is why the same grape tastes different in different places.

What are tannins in wine?

Tannins are polyphenol compounds from grape skins, seeds, and oak barrels that create a drying, astringent sensation in your mouth — similar to strong black tea. They're found primarily in red wine and serve as natural preservatives, giving wine structure and ageing potential. Tannins soften over time, which is why young age-worthy reds can taste harsh but become smooth with cellaring.

What does body mean in wine tasting?

Body refers to the weight and texture of wine in your mouth — light, medium, or full. Light-bodied wines feel like skim milk (Pinot Grigio, young Beaujolais). Full-bodied wines feel like cream (Barolo, Napa Cabernet). Body is determined by alcohol, tannin, extract, and residual sugar.

What is the difference between Old World and New World wine?

Old World refers to traditional European wine countries (France, Italy, Spain, Germany). New World refers to newer wine-producing countries (USA, Australia, Chile, South Africa). Old World wines tend to emphasise terroir and subtlety; New World wines often emphasise fruit and winemaker technique. The distinction is becoming less clear as both worlds evolve.

What does minerality taste like in wine?

Minerality is a non-fruity taste sensation — wet stone, chalk, flint, or a saline quality. It's most commonly associated with white wines grown on limestone or volcanic soils (Chablis, Santorini, Mosel Riesling). The taste is real and consistently described, even though the exact cause is scientifically debated.

How do I read a wine label?

Key elements: Producer name (who made it), Appellation (where the grapes were grown), Vintage (harvest year), Grape variety (may not appear on Old World labels — the appellation implies it). In France, the appellation tells you the grape: Chablis = Chardonnay, Sancerre = Sauvignon Blanc, Pommard = Pinot Noir.

Wine Terminology Decoded: 50 Essential Terms Every Wine Lover Should Know

Master the language of wine without the pretension

Updated April 2026 | By expertvin — Belgium's Wine Specialist

Wine has its own language, and that language can be intimidating. Terms like "malolactic fermentation," "terroir," and "flabby" are thrown around by professionals and enthusiasts as if everyone knows what they mean. If you've ever nodded along while secretly wondering what "minerality" actually tastes like, this guide is for you.

We've selected 50 terms that appear most frequently on wine labels, in tasting notes, and in conversation — and explained each in plain English with practical examples. Bookmark this page for reference when browsing expertvin.be or reading wine reviews.

Vineyard & Winemaking Terms

Terroir

The complete natural environment of a vineyard — soil, subsoil, climate, altitude, aspect, drainage, and microorganisms. Terroir is why the same grape variety tastes different in different places. It's the most important concept in fine wine and the reason a Puligny-Montrachet costs more than a generic Bourgogne Blanc — both are Chardonnay, but the terroir is incomparable.

Appellation (AOC/AOP/DOC/DOCG)

A legally defined wine-growing area with specific rules about grape varieties, yields, and winemaking. The more specific the appellation, the higher the perceived quality. "Bourgogne" is broader than "Pommard," which is broader than "Pommard Premier Cru Les Épenots." Each step narrows the geography and raises the bar.

Cru

Literally "growth" — a classified vineyard or estate. In Burgundy, Premier Cru and Grand Cru are vineyard-level classifications. In Bordeaux, cru classé refers to estate-level classifications (First Growth through Fifth Growth). In Beaujolais, cru designates the 10 best villages (Fleurie, Morgon, etc.).

Malolactic Fermentation (MLF)

A secondary fermentation where bacteria convert sharp malic acid (green apple) into softer lactic acid (cream). Almost all red wines undergo MLF; for whites, the winemaker decides — MLF gives Chardonnay its buttery richness, while blocking it (as in Chablis) preserves crisp, appley freshness.

Lees / Sur Lie

Lees are dead yeast cells that settle after fermentation. Ageing wine on its lees (sur lie) adds richness, texture, and a biscuity, bread-dough character. Muscadet Sur Lie, Champagne, and barrel-aged Chardonnay all benefit from lees contact. Bâtonnage is the practice of stirring lees for even more texture.

Botrytis (Noble Rot)

A beneficial fungus (Botrytis cinerea) that concentrates sugars and acids in grapes, producing lusciously sweet wines. Sauternes, Tokaji, and German Beerenauslese/Trockenbeerenauslese are all botrytis wines. The fungus only works in specific climatic conditions — alternating morning mist and afternoon sunshine.

Tasting Terms

Tannin

The drying, gripping sensation in red wine — the same compound found in strong black tea. Tannins come from grape skins, seeds, and oak barrels. High tannin feels astringent and mouth-drying; well-integrated tannin feels smooth and velvety. Tannins soften with age, which is why young Barolo can be mouth-puckeringly tannic but becomes silky after 15 years.

Acidity

The fresh, mouth-watering quality in wine — think lemon juice. High acidity makes wine taste crisp, lively, and refreshing (Riesling, Champagne). Low acidity makes wine taste soft, round, or "flabby" (a negative term). Acidity is the backbone that gives wine its structure and ageing potential.

Body

The weight of wine in your mouth — light, medium, or full. Compare milk: skim milk is light-bodied, whole milk is medium, cream is full-bodied. Pinot Noir is typically light to medium-bodied; Cabernet Sauvignon is medium to full-bodied. Body is influenced by alcohol, tannin, and extract.

Minerality

One of wine's most debated terms. It describes a non-fruity, non-herbal quality — wet stone, chalk, flint, saline — that many associate with terroir expression. Whether minerals from soil literally translate to flavour in wine is scientifically questionable, but the taste sensation described as "mineral" is real and consistently recognised by tasters.

Finish / Length

How long the flavour lingers after you swallow. A long finish (10+ seconds of evolving flavour) is a hallmark of quality wine. A short finish (flavour disappears immediately) suggests simpler wine. Top Grand Cru Burgundy can have a finish lasting 30+ seconds — an extraordinary sensory experience.

Complexity

The number of different flavours and aromas you can identify in a wine. A simple wine might show just "red fruit." A complex wine reveals layers: cherry, then tobacco, then leather, then earth, then spice — each sniff and sip uncovering something new. Complexity develops with age and comes from quality terroir and winemaking.

Label & Classification Terms

Cuvée

In Champagne, cuvée means the first, best pressing of grapes. Elsewhere, it's used loosely to mean a specific blend or batch — "Cuvée Prestige" or "Cuvée Spéciale" indicates a producer's top selection. In practice, it's often marketing language — judge the wine on its own merits, not the name.

Réserve / Riserva

In Italy and Spain, Riserva/Reserva has legal meaning — the wine has been aged longer than standard (e.g., Chianti Classico Riserva requires 24 months vs. 10 for regular). In France and most other countries, Réserve has NO legal meaning — it's marketing. An Italian Riserva guarantees extra ageing; a French Réserve guarantees nothing.

Vieilles Vignes (Old Vines)

No legal definition in most countries, but generally means vines 35+ years old. Older vines produce fewer, more concentrated grapes and deeper root systems that access more terroir complexity. "Vieilles Vignes" on a label is usually a genuine quality indicator — old vines cost more to maintain and produce less.

Mis en Bouteille au Château / Domaine

"Bottled at the estate" — the wine was made and bottled by the producer who grew the grapes. This indicates the wine hasn't been sold in bulk to a négociant. Generally a quality indicator, as the producer controls the entire process from vine to bottle.

Quick Reference: Common Descriptors

CrispHigh acidity, refreshing — typically used for whites

RoundSoft, smooth, low tannin/acidity — pleasant but may lack structure

AustereRestrained, closed, needs time — common for young Barolo, Bordeaux

OpulentRich, generous, full-bodied — think Amarone, Napa Cabernet

ElegantRefined, balanced, not heavy — the highest compliment for Burgundy

StructuredGood tannin/acidity framework — built for ageing

FlabbyLacks acidity — tastes dull and lifeless (negative)

GrippyNoticeable tannin — not necessarily negative, may soften with age
