Just for fun, the Daily Beast has a piece on marijuana wine. 

Bud said he is just one of a number of winemakers on the Central Coast who are blending two of California’s most prized crops. The recipe for pot wine, such as it is, consists of dropping one pound of marijuana into a cask of fermenting wine, which yields about 1.5 grams of pot per bottle; the better the raw materials—grapes and dope—the better the wine.

The fermentation process converts the sugar in grapes into alcohol, and alcohol extracts the THC from marijuana. Bud goes for maximum extraction: he keeps his weed wine in barrel for nine months before bottling it. He said he and other winemakers produce pot wine in small quantities, to be shared in “convivial moments with like-minded people.” Those who enjoy it evidently enjoy it a lot: Bud said that at certain wine events in San Francisco, New York, and Las Vegas, “I can’t show up unless I have some with me.”

The article claims that  “much of the marijuana used for wine comes from Humboldt County, which is California’s weed capital.” Hmm, I wonder if any of our local winemakers are trying this…
