Frost Prevention

I'm knocking on wood as I type this. So far, we've made it through March and April with minimal danger of frost damage in Alexander Valley. For a period after bud break and until grapes begin to set, grape vines are super delicate and most vulnerable to adverse weather. Just one overnight freeze could really wipe out an entire year's crop.Some grape growers burn diesel to ward off frost. Some blast millions of gallons of water over their fields. At Hawkes, a good defense against frost involves sleepless nights and a handful of American-made V-8 engines.
