I often tell people that you can’t be a farmer if you don’t love the weather. More precisely, I mean that we must accept the fact that the weather is beyond our control and we adjust our schedule and practices accordingly. It’s important to keep this in mind as we ride the roller coaster that is harvest.
This week, we’re experiencing our annual Indian Summer—that last bit of warm weather that finishes harvest. We’ve had some of the warmest weather of the year during this period, with temperatures in the high 90s. This is due to high pressure moving over our area and the presence of Santa Ana conditions—a warm offshore flow as opposed to our typical pattern of cool onshore breezes. This mini heat wave came right on the heels of a rainstorm last week that dumped just over an inch of rain in the Arroyo Grande Valley.
At this point, everything on our ranches has been harvested with the exception of some chardonnay in the Rincon Vineyard, which we will finish on Monday. The other exception is about three tons of sauvignon blanc in Oliver’s Vineyard that we will attempt to make into a sweet dessert wine. The rain we received last week created perfect conditions for botrytis cinerea, often referred to as the “noble rot.” Botrytis is a fungus that grows ongrapes due to wet conditions and which causes the grapes to shrivel and the sugar and acid to become extremely concentrated. This is undesirable in most of the wines we produce, and we typically go to great lengths to prevent it, including leaf removal and thinning of infected grape clusters. Botrytis is critical for the production of white dessert wines and sauvignon blanc is one of the white grape varieties most suited to make this wine. Consequently, we decided to leave those grapes on the vine with the hope to let botrytis grow and to make our second ever late harvest sauvignon blanc. The only other time we did this was in 1994, when we had a very rainy harvest. That wine was legendary.
So here’s another way of expressing my “learn to love the weather” mantra: when you have lemons, make lemonade. When you have rain, make dessert wine!
