Still wine, definition

Realizing that this definition may still be unsatisfactory in that the man in the street may not agree with the expert, we shall nevertheless consider California grapes and the wines made from them from the point of view of this understanding of quality. 

Consequently, the definition of maturity varies, depending on the objective. For example, the production of dry white wines requires grapes whose aromatic substances are at a maximal concentration and whose acidity is still sufficient. In certain situations, an early harvest can be interesting. Conversely, when the elaboration of a quality red wine is desired, grape development must be left to continue to obtain the most easily extractable phenolic compounds.
