Am assuming you mean wineries on the 128 out to Ft. Bragg. First winery
is Yorkville Cellars, organic Bordeaux Style wines, then in Philo there's Roederer Champange, Navarro Winery, great Anderson Valley reds/whites. Stop by Gowan's fruit stand for apples, cider,etc also in Philo. Fort Bragg has winery Called Pacific Star with tasting room in the Skunk Train Depot-winery located 10 miles north and on the coast.
Checkout avwines.com for more wineries. None are touristy. This area well known
For pinots, syrah not so much.
Many thanks for referral to the excellent, informative avwines.com. The site has an Andersoon Valley winery map with a legend indicating which wineries have tasting rooms, as well as links to the individual winery websites. Definite stop planned at Navarro, which distributes to restaurants but not to wine shops.
