Time in the annual growth cycle the grapevine as part of maturation = Ripening phase of the berries (see also under BBCH Code ). This term was created in the Anglo-Saxon language in the 1990s and is derived from "gustus" (Latin for taste). This refers to a special phase during ripening, in which the variety-specific flavorings and the color intensity mint. Biochemical processes that differ from those of the Sugar- and acidification differ. This not previously distinguished section within the growth cycle of vine is part of the late ripening period, when the water pipe (xylem) in the berries is already stopped and these already shrink slightly again. From the sugars stored in the berry are now increased glycosides (Aromas or primary flavors) formed. This is done in parallel with the maturation of phenolic compounds such as tannins and anthocyanins (Dyes). The ideal condition is as optimal as possible physiological maturity given to the grapes.
