The last three years have seen wildfires, smoke taint, severe drought and above average temperatures during the growing season. Generally, vines are stressed. 2021 yields were down 40-60 percent for many growers. One wine maker said he thought it could take several years of normal rainfall to bring yields back to expected levels. He worries about the continuing drought, the increasing cost of water, and the possibility of future water restrictions. Recent surveys indicate a greater incidence of Delayed Spring Growth (DSG) brought about by dry, cold conditions. This is especially true for certain varietals and young vines.
