This Thankful Thursday I’m thankful for Napa Valley wines. And I’m a beer guy, not an oenophile, which is apparently a wine lover. A word I’d probably have already known if I actually loved wine. I might seldom partake in their beverages, but I’m thankful for them after seeing a story recently about how they are beginning to “go green.” More and more of the vineyards in that California valley are turning away from chemical pesticides and towards organic solutions…including owls!
Wine might be healthy for us in moderation, but creating it isn’t always healthy for the land. Growing the grapes invites a lot of nuisance animals to the area… rats and mice especially. For much of the past century, the growers relied on heavy doses of pesticides to keep the rodents in check. Needless to say, this isn’t beneficial. Besides the rodents they’re looking to control, other animals can ingest it and die, or eat the poisoned rats and in turn sicken or die themselves as the poison builds up inside them. And while one would imagine that the amounts of pesticide retained by the grapes during the production would be minimal, the risk to farm workers is real. For instance, zinc phosphides, a common type of rat poison will “increase calcium levels in the blood, leading to organ failure” according to scientists. One would think even a trace amount lingering in the wine wouldn’t be doing its enthusiasts any good and working in the fields with it day in, day out even less so.
So, I’m happy more and more grape-growers are shunning the chemicals and instead encouraging owls. Barn Owls in particular, an especially effective rodent weapon. Apparently a typical one will eat close to ten critters a night, so just a couple of pairs of nesting ones is going to significantly lessen the enjoyment of the area for rats! The vineyards are cleaner, and the growers save money. It costs far less to put up a few nestboxes for owls than to buy pounds of chemicals, needless to say. They may even reap a small financial reward as birdwatchers begin to take the vineyard tours in hopes of seeing a striking-looking owl more than tasting a fine Chardonnay. And the Barn Owls, declining in numbers across the country are finding new homes with ready supplies of food. A win-win.
Organic wine, helped along by owls. I’ll drink to that. Or should I say, “owl” drink to that!
