As Grapes Turn Ripe

We often mention ripeness of grapes in wine tasting classes and events. When is the ideal harvest time for grapes? Every winery owner has his own set of standards, and there is no rule set in stone. Most large wineries with big annual production determine using the acidity and sugar level of grapes, which is easier to control. Some owners try the grapes themselves to determine whether the tannins have reached the ideal level of maturity.
