Renewable winemaking —often called green or sustainable winemaking—is a holistic approach that focuses on minimizing the environmental footprint of production while regenerating the land. Here is the step-by-step journey from vine to glass, highlighting modern shifts. 1. Harvest & Sorting The Decision: Winemakers now use satellite imagery and AI sensors to measure grape ripeness (Brix, pH, and acidity) in real-time, picking the exact hour for harvest. The Action: Grapes are picked by hand (for premium styles) or by "optical sorters"—machines that use high-speed cameras to "flick" away any grape that isn't the perfect color or shape. 2.

White Wine: Grapes are immediately pressed to separate the juice from the skins to keep the wine crisp and clear. 3. Fermentation (The Ma...
