(Marinij) - AS FAMILIES SIT DOWN to enjoy a Thanksgiving meal with loved ones this year, it's more likely than ever that a bottle of wine made right here in Marin will be on the table. At 200 acres, Marin's wine industry is positively tiny compared with its behemoth neighbors, Napa (45,000 acres) and Sonoma (22,000 acres) counties, but it is growing as its wines gain recognition as comparable to those from Burgundy and the Sonoma coast. It takes persistence, hard work and deep pockets to farm and process wine grapes in Marin. And Marin's been growing wine grapes since 1817, thanks to missionaries at the San Rafael Mission, according to Pey-Marin Vineyards of San Anselmo. By the end of the century, vines were planted as far south as Magnolia Avenue in Larkspur.
