In the southern corner of El Dorado County, nestled into the Sierra Nevada foothills, is the tiny township of Fair Play. Founded in the 1850s as a mining town, the area quickly became known for its fertile ground. It’s now home to more than 20 wineries and dozens of farms and ranches. Brian Fitzpatrick and his wife Diana were the first people to start a winery in the area and he’s written a memoir about his experience titled, Confessions of a Winemaker. He’ll be signing books at Shadow Ranch Winery in Fair Play this Sunday.
