Wine vines are dormant during the winter. As long as there was no bud break yet, the freeze will not affect wine production or quality IMO.
“As long as there was no bud break yet”
Got some pics from a friend in SoCal yesterday. They have spring flowers. Hope Pelosi’s vineyard is hit, and her buds have broken, and she gets sour grapes!
That’s good to know—it’s hard to bring grape vines indoors on short notice, especially if you have a vineyard with thousands of vines.
