This summer, a series of wildfires swept through parts of California. Triggered by extremely dry conditions and dry lightning, the fires raged through parts of Northern California where grapes are grown. I was on the Mendocino/Sonoma border throughout this summer's fire season, and though were were tens of miles from the fires, we woke every morning to the smell of smoke in the air and that persisted all day. (photo of the fires in Mendocino by shellove)At the time, I thought it was highly unlikely that the taste of the grapes would be affected by the smoke. It looks like I may be wrong.
In a story in the Santa Rosa Press Democrat, Kevin McCallum reports that growers are worrying because their fruit is giving off unusual odors. Scientists are currently analyzing the juice from Mendocino grapes to test for smoke taint. There is some concern that even low levels of smoke taint in the grapes will be amplified in the flavors during fermentation. While winemakers can use all kind of sophisticated filtering to get rid of some of the undesirable flavors out of the wine, at this point no one is clear about the extent of the problem or what--if anything--to do about it.
One of the questions I have is about how our famously subjective tastebuds will factor into this developing situation. Are some people going to taste smoke when they taste 2008 Mendocino and Anderson Valley wines? Will these tasters be in the majority? Or, like cork taint, will smoke be something that many tasters can't even detect in the wines?
It's too early to tell at this point. What I know for sure is that there's not much that will keep me away from continuing to buy North Coast and Mendocino favorites from vineyards like Navarro (which was only a mile and a half from some of the worst fires this summer). If anyone has any thoughts on this issue from a scientific, tastebud, or environmental perspective, please share them. I'm still kind of amazed that the grapes weren't able to flush any smoke that got into their tissues back out again over the course of the growing season.
