A guide from Saatolog that will help you get to know wine and its world better


Acid: A natural part of wine that creates a lively taste and balances out the sweet and bitter components. Too much acid results in an overly tart, sharp, or sour wine; too little makes it flat and flabby. Acetic acid, citric acid, tartaric, malic acid, and lactic acid are the most common.

Acidity: The natural liveliness / crispness that activates salivary glands, and a leading determinant of balance of a wine.

Aroma: The smell (or smells) of wine (see “bouquet” for more).

Aeration: Exposing wine to air so that it can “breathe” before drinking it. When oxygen is introduced to wine, it releases aromas and opens up flavors much like swirling wine in a glass does.

Aftertaste:The taste or flavors that linger in the mouth after tasting wine, also known as “finish.” This is the most significant factor in assessing a wine’s character and quality. 

Aging: holding wine in barrels, tanks, and bottles to advance them to a more desirable state

Alcohol By Volume: A measure of the alcohol levels in an alcoholic beverage, often truncated to ABV. The average glass of wine contains about 11-13% alcohol, but bottles can range from 5.5-20% ABV. 

Appellation: A legally defined geographical name that identifies where wine grapes were grown. In France, the Appellation d’Origine ContrĂŽlĂ©e (AOC) is the official certification for designated regions. In the United States, appellations are called American Viticultural Areas (AVAs) — examples include Paso Robles, Sonoma Coast, and Napa Valley.
