Annual Growth Cycle of the Grapevine


As harvest approaches, the grape is considered ripe when the sugar and remaining acids are well balanced. A grower may choose to harvest the grapes before they are ripe, at their point of ideal ripeness, or when they are overripe; it all depends on the style of wine desired by the vintner. For example, Pinot Noir grapes for sparkling wine production are harvested much earlier, at lower sugar and higher acid content, than Pinot Noir for non-sparkling red wine.
