Worry Wine

San Francisco Chronicle reports Napa news:

The worst spring cold snap in more than 30 years is threatening to wreak havoc on the wine industry as three recent days of frost have killed grapevine buds up and down the crucial North Coast vineyard region. ...

The most damage to vines took place March 31 and last Saturday and Sunday, when temperatures dipped below the freezing point of 32 degrees to as low as 27 degrees....

The North Coast growing region is the premier wine land in America, anchored by Sonoma and Napa counties and stretching from Marin to Mendocino and Lake counties. Producing 450,000 tons of grapes every year, it is a $1 billion industry, so even a 10 percent loss would be huge in terms of dollars, growers said.
