When I think of the 2022 vintage in California, the unique “heat dome” of the growing season comes to my mind – when areas such as Napa and Sonoma counties experienced some of the hottest and driest days in the history of vine growing.
However, that weather event is easy to forget when you taste pinot noirs and chardonnays from top producers from such regions as Sonoma Coast, Russian River, Anderson Valley and Carneros. Even some who picked mostly after the scorching temperatures, which reached as high as 118 degrees Fahrenheit (47.7 Celsius), made tensioned and focused wines.
Extreme heat is produced by heat domes and they are created by a “strong change in ocean temperatures from west to east in the tropical Pacific Ocean,” according to the National Oceanic and Atmospheric Administration. That steamy air becomes trapped under a dome-like area of high pressure, causing “vast areas of sweltering heat,” the agency said.
