(CBS News) - Just in time for 4/20, reports have surfaced that an increasing number of California winemakers are turning to another locally produced intoxicant. The Daily Beast reports several California winemakers are creating blends of marijuana-infused wines on the sly. According to The Daily Beast, pot wine is made by placing a pound of marijuana in a cask of wine, leading to about 1.5 grams of marijuana per bottle. The fermentation process converts sugar from grapes into alcohol, and the alcohol extracts the THC from marijuana over a nine-month process.
