Some Lodi winegrape growers are reporting grapevines and vineyard blocks with no vine growth or stunted vine growth this spring that appears to be related to cold injury damage experienced during an unusual cold weather event that occurred November 8-12, 2020 when overnight/morning temperatures dropped below freezing throughout most of the Lodi AVA.
Although the cold event occurred post-harvest with no impact on the 2020 crop, most vines were not yet dormant, and it is believed that vines had not become seasonally acclimated to prevent cold damage to vascular tissues. Younger and more recently planted vines were more susceptible, however, damage has also been observed in vineyards up to 20 years old.
