Cloverdale,CA -- Winegrape growers and vintners from Mendocino and Sonoma counties petitioned the Alcohol and Tobacco Trade Bureau to create a 4,600-acre American Viticulture Area, tentatively called the Pine Mountain-Mayacmas AVA. No, that’s not a typo: Although the name Mayacamas is well-known within the wine industry as both a mountain range and a Napa County winery, Mayacmas is the official spelling used on USGS maps, and hence it was used as a geographic modifier to pinpoint the location of this particular Pine Mountain. In the petition as published, TTB specifically requests comments about the alternate spelling, as well as any conflicts with existing brands.
