The Glera grape is the cornerstone of Prosecco DOC, comprising at least 85% of the blend in both standard and rosé versions. It grows in large, loosely packed bunches with a golden-yellow hue when ripe, typically harvested between late August and early September to ensure ideal sugar, acidity, and aroma balance. Prompt transport to the cellar preserves its delicate character. With generous yields of up to 18 tonnes per hectare, Glera may be blended with up to 15% of other varieties—both native and international—to enhance complexity. This versatile grape defines Prosecco’s signature freshness, elegance, and aromatic profile.
