Wine Glossary: Essential Wine Terms Explained

An appellation is a legally protected wine-growing region with regulations governing grape varieties, yields, and winemaking practices. It guarantees geographic origin and a baseline standard of production.

Acidity refers to the tart, crisp quality in wine that makes your mouth water and provides freshness. It is a key structural component that affects balance, food pairing, and aging potential.

Body describes how heavy or light a wine feels in your mouth, ranging from light-bodied to full-bodied. It is influenced by alcohol level, residual sugar, and extract concentration.

Bouquet refers to the secondary and tertiary aromas that develop in wine through aging, such as leather, tobacco, and dried fruit. It is distinct from the primary fruit aromas of a young wine.

Decanting means pouring wine from the bottle into a separate container to expose it to air and separate it from sediment. It helps young wines open up and older wines serve clear.

Demi-sec means 'half-dry' in French and describes wines with noticeable sweetness. In Champagne, it indicates a sweetness level of 32-50 grams of residual sugar per liter.

Malolactic fermentation is a process where bacteria convert tart malic acid into smoother lactic acid, giving wines a softer, creamier texture. It is standard in red wines and buttery-style Chardonnays.

Maceration is the soaking of grape skins, seeds, and stems in juice to extract color, tannins, and flavors. It is the key process that gives red wine its color and tannic structure.

Minerality describes stone-like, flinty, or chalky flavors and textures in wine. It is commonly associated with cool-climate white wines, though its exact origin remains scientifically debated.

Tannins are natural compounds from grape skins, seeds, and oak barrels that give wine its characteristic dry, astringent mouthfeel. They are most prominent in red wines and contribute to a wine's structure and aging potential.

Terroir is the combination of soil, climate, topography, and local conditions that give a wine its unique character and sense of place. It explains why the same grape variety tastes different when grown in different locations.

Tasting notes are the structured written record of a wine's characteristics (appearance, nose, palate, and conclusions) used to analyse, remember, and communicate about wine.

A varietal is a wine labeled by its dominant grape variety, such as Merlot or Chardonnay. Most wine laws require at least 75-85% of the named grape to use a varietal label.

Vintage refers to the year in which a wine's grapes were harvested. It indicates the growing conditions of that year and helps determine a wine's character and aging potential.
