Santa Maria,CA - Winegrape growers ask TTB to add 18,700 acres to their viticulture area.After the Alcohol and Tobacco Tax and Trade Bureau (TTB) rejected a 2006 petition to expand the Santa Maria Valley AVA (American Viticulture Area), members of Santa Maria Valley Wine Country rallied their resources and redrew their proposal. This time, the TTB deemed the proposal “merits consideration and public comment,” and posted it on the bureau’s website March 8.
