Balanced - In tasting terms, a ‘well balanced’ wine is one where the tannins, sugars, alcoholic strength and acidity all complement each other on the palate, with no element becoming overpowering. It is not related to the flavours of the wine.
In vine terms, balance refers to the leaf to fruit ratio - wine makers strive for the perfect balance between the two in order to produce the finest vines and therefore, the finest wines.
Bouquet - A tasting term for a wine’s smell, aroma, or perfume - it is often used in reference to more mature wines. Rather than suggesting that the smell is flowery, the term is instead used to describe the general pleasant aroma of a wine (much like a bouquet of flowers is a composition of several different flowers).
Breathing - In wine terms, ‘letting the wine breathe’ refers to pulling the cork and letting the open bottle stand for some time before consumption. Experts dispute the efficacy of this practice, as the bottle opening is so small that oxygen intake would be minimal. Decanting would be seen as a more effective means of aeration.
