On May 17, 2022, the Lodi Winegrape Commission hosted about 70 local growers and winemakers in Burgundy Hall at the Lodi Grape Festival Grounds to discuss winegrape quality in depth. The speakers and topics included:
-
- Greg La Follette (Winemaker) – Creating flavor in the vineyard
- Kaan Kurtural, PhD (UC State Extension Viticulturist) – Berry quality metrics
- Daniele Zaccaria, PhD (UC) – Irrigation and berry quality
