San Diego, Calif. -- When the San Diego County Board of Supervisors unanimously approved an ordinance permitting winegrowers in unincorporated, agriculture-zoned areas to open tasting rooms, members of the Ramona Valley Vineyard Association thought they’d finally triumphed in a years’ long battle to put their AVA on the consumer map. The ordinance, originally proposed in 2007, won approval Aug. 4, and became effective Sept. 4.Whether the growers and winemakers will ever enjoy the fruit of their struggle remains to be seen, however. On Sept. 3, an ad hoc group of property owners calling itself “the San Diego Citizenry Group,” filed a lawsuit challenging the ordinance. The suit contends that the ordinance was passed without a proper environmental study, and asks that the supervisors’ vote be annulled.
