I'm planning to go to the Paso Robles Zinfandel Festival this weekend, March 18 thru 20th. Wondering which wineries I should visit to taste, and buy, the best zin? I'm inclined toward visiting Carmody McNight, Castoro Cellers, Eberle, Justin, Linne Calado, Nadeau Family Vintners. There are dozens more in the weekend brochure from PasoWine.com to choose from. So many choices. So little time. If I'd planned ahead I might have gone to one of the winery dinners.
