Glossary

Wine Terms & Wine Lingo

Learning some wine terminology is often the first step to increasing your wine knowledge. Use our list below to help you along as you encounter new wine lingo.

Acids

Acids give wine tartness. Several acids are in the grape before fermentation, and others arise afterward. Acids often make a wine seem “crisp” or “refreshing.”

Aftertaste

A tasting term for the taste left on the palate after wine has been swallowed. "Finish" is a synonym.

Aging barrel

A barrel, often made of oak, used to age wine or distilled spirits.

Alcohol

Generally refers to ethanol, a chemical compound found in alcoholic beverages. It is also commonly used to refer to alcoholic beverages in general.

Altar wine

Alternative wine closures

Various substitutes used in the wine industry for sealing wine bottles in place of traditional cork closures.

A.O.C.

Abbreviation for Appellation d'Origine Contrôlée, (English: Appellation of controlled origin), as specified under French law. The AOC laws specify and delimit the geography from which a particular wine (or other food product) may originate and methods by which it may be made. The regulations are administered by the Institut National des Appellations d'Origine (INAO).

Appellation of Origin

You might see this phrase on a wine label. It denotes the place where most of the grapes used in the wine were grown. An appellation of origin can be the name of a country, state, county or geographic region. Federal regulations require that at least 75 percent of the grapes must be grown in the named appellation of origin.

Aroma

The smell of a wine. The term is generally applied to younger wines, while the term Bouquet is reserved for more aged wines.

Astringency

The degree of astringency (how much a wine makes your mouth pucker) depends upon the amount of tannin a wine has absorbed from the skins and seeds of the grapes. A moderate amount of astringency is desirable-it creates a lovely flavor-in many red wine types.

ATTTB

Abbreviation for the Alcohol and Tobacco Tax and Trade Bureau, a United States government agency which is primarily responsible for the regulation of wines sold and produced in the United States.

Balance

A wine has balance when its elements are harmonious; when no one part dominates. Acid should balance against sweetness; fruit should balance against oak and tannin; alcohol balances against acid and flavor.
