Wine Tasting Terminology: A Reference Glossary

Wine tasting has its own precise vocabulary — a shared language that lets tasters communicate sensory experience with enough accuracy to be useful across continents, vintages, and professional contexts. This glossary covers the core terms used in wine evaluation, from structural descriptors like acidity and tannin to more nuanced concepts like mouthfeel, finish, and typicity. Whether preparing for a wine education certification or simply trying to decode a tasting note, these definitions anchor the vocabulary in what actually happens in the glass.

Definition and scope

A tasting term is a descriptor with agreed-upon sensory meaning — not a poetic flourish, but a technical signal. The Wine & Spirit Education Trust (WSET), whose Systematic Approach to Tasting (SAT) is used across more than 70 countries, organizes descriptors into discrete categories: appearance, nose, palate, and conclusions. The Court of Master Sommeliers employs a comparable framework, though with slightly different terminology conventions.

The scope of tasting vocabulary divides broadly into two families:

Structural terms describe measurable or semi-measurable components — acidity, tannin, alcohol, sweetness, and body. These are the load-bearing walls of any tasting note.

Aromatic and flavor descriptors are more associative, mapping a wine's sensory profile onto recognizable reference points: stone fruit, wet slate, graphite, dried herbs. These terms have no fixed chemical definition, but within established frameworks they carry consistent meaning.

The gap between the two is where tasting notes can either illuminate or mystify. A wine described as having "high acidity" communicates something unambiguous. A wine described as "tasting like a forest after rain" communicates something vivid but imprecise — which is fine, as long as the structural scaffolding is already in place.

How it works

The WSET SAT framework evaluates a wine in four sequential stages, each with defined terminology:

  1. Appearance — Clarity (clear, hazy), intensity (pale, medium, deep), and color (lemon, gold, amber for whites; purple, ruby, garnet, tawny for reds). A deep ruby with purple edges signals a young red; garnet with a tawny rim suggests age.

  2. Nose — Condition (clean or faulty), intensity (light, medium, pronounced), and aroma characteristics divided by origin: primary (fruit, floral, herbal — from the grape itself), secondary (yeast-derived, e.g., brioche, cream), and tertiary (oak and oxidative aging, e.g., vanilla, toast, leather).

  3. Palate — Sweetness (dry to sweet), acidity (low to high), tannin for reds (low to high, with texture qualifiers: grippy, silky, chalky), alcohol (low below 11% ABV, high above 14%), body (light, medium, full), flavor intensity, flavor characteristics, and finish length — typically measured in seconds, with a finish under 3 seconds considered short and one over 7 seconds considered long.

  4. Conclusions — Quality assessment and readiness to drink. WSET uses the scale: faulty, poor, acceptable, good, very good, outstanding.

Tannin deserves particular attention because it's the descriptor most commonly misused. Tannin is a phenolic compound derived primarily from grape skins, seeds, and stems — and from oak barrels. Tannin binds with proteins, creating the drying, gripping sensation on the gums and inner cheeks. It is not bitterness (which is a taste), and it is not astringency (which is the broader tactile category tannin belongs to). Confusing these three in a tasting note is one of the more reliable signs of early-stage wine literacy.

Common scenarios

Three situations illustrate where precise terminology proves its value:

The sommelier context. A sommelier describing a wine to a guest needs vocabulary that bridges technical accuracy and accessibility. Describing a white Burgundy as having "high acidity and no oak" conveys structure; adding "lemon curd and white peach on the nose" provides texture. The how to taste wine framework outlines the sequencing that makes this translation reliable.

The blind tasting context. Blind tasting in certification exams — WSET Diploma, Master of Wine, Court of Master Sommeliers Advanced — requires tasters to build a defensible argument from sensory evidence alone. Here, structural terms are not decorative; they are the evidence chain. Deep ruby with purple hints → high tannin, high acidity, black fruit → suggests Cabernet Sauvignon or Nebbiolo in a warm vintage.

The retail and label context. Descriptors on back labels and shelf talkers compress tasting notes into 30 to 50 words. Evaluating wine quality and scores becomes easier once readers understand what a descriptor like "medium-plus body with a persistent finish" is actually measuring.

Decision boundaries

Several pairs of terms are close enough in meaning to cause consistent confusion:

Aroma vs. Bouquet. Aroma refers to scents derived from the grape variety itself (primary aromas). Bouquet refers specifically to scents developed through winemaking and aging (secondary and tertiary). A young Sauvignon Blanc has aroma; a 20-year-old red Burgundy has bouquet.

Dry vs. Not Sweet. Technically, a wine is dry when residual sugar falls below 4 grams per liter — the threshold at which most tasters cannot perceive sweetness. But high acidity can mask residual sugar, and high alcohol can mimic sweetness on the palate. A wine can taste off-dry while technically qualifying as dry by TTB labeling standards.

Finish vs. Aftertaste. Finish refers to the duration and character of flavor that persists after swallowing. Aftertaste specifically denotes any flavor impression that differs from the mid-palate experience — not merely its continuation. A wine can have a long finish that is entirely clean, or a short finish with an unexpected bitter aftertaste.

Typicity. This is the degree to which a wine expresses the expected character of its grape variety and region. The concept sits at the intersection of American Viticultural Areas and varietal identity — a Willamette Valley Pinot Noir with high typicity tastes unmistakably like Willamette Valley Pinot Noir, not like its counterpart from Burgundy or Santa Barbara.

Tasting vocabulary, used well, is not gatekeeping — it's the common shorthand that lets a winemaker in the Finger Lakes and a buyer in Chicago talk about the same bottle without standing in the same room. The full scope of wine knowledge covered across this reference network returns, repeatedly, to this vocabulary as its foundation.
