This is a concept that on the surface seems very simple, but that turns out to be quite challenging. It is important to have some familiarity with what balance entails if you are to become a good wine taster.
Balance in wine refers to the interaction and harmony between two or more of the wine’s constituents. By far the most straightforward balance is that between sugar and acidity. Not all wines, of course, have residual sugar, though all have some acidity. Sugar-acid balance is thus limited to wines which have an interplay between these two elements.
There is no accurate formula for calculating the perfect acid-sugar balance in a wine, despite the fact that there are some people who advance that very notion. In its simplest sense, a wine which has a good acid-sugar balance tastes neither too sweet nor too acidic: the sugar exists in the right quantity for the acid, and vice versa.
