The Frost of 2008

Every now and then, natural circumstances conspire to remind us of our place in the order of things. This year, Mother Nature has collaborated with Jack Frost to inflict upon us one of the harshest frost seasons in perhaps the last 30 years. Certainly the coldest I can recall, although our Dad will have ‘fond’ memories of farming challenges all the way back to 1970.
Frost season can be exhausting for the guys in the field who have to monitor the cold temperatures closely in order to protect the fragile young shoots. Our vineyard manager, Angel Avina, who has been with us better than 20 years has spent many a cold lonely night this season in the vineyard watching the mercury drop and determining just the right time to either fire up the wind machines or crank up the pumps in the pumphouse for the sprinklers.
In general, the sprinklers are a more effective method of combating the cold, as there is a constant supply of fresh water applied to the vines, which keeps the vines at a cool 32F or so as the water continually rotates through freeze/thaw cycles. Wind machines work by moving the air throughout the vineyard and pulling down the warmer air layer to keep the green shoots from freezing.
Thanks to Angel’s valiant efforts, we’ve experienced little to no damage in our vineyards under sprinkler. We did suffer a little frost damage on the perimeters of our wind-machine protected vineyards. While this won’t impact the quality of the fruit we bring in (we’ll isolate any affected vines), it will decrease our crop a bit.
At the end of the day, another reminder of whose ultimately calling the shots and also that as winegrowers, we’re essentially glorified farmers whose primary responsibility is to navigate the growing season and guide our crop into the barn as safely as we can …
