Hey, we belong to Sunce, too - since about 2003. Maybe we've run into each other at barrel tasting. We belong to quite a few (too many). Sunce, because I am of Croatian Ancestry, Frane and the staff are great, and I like staying stocked with a bunch of their Cabs and Meritages. Incidentally, we brought a bottle of Sunce's 04 "Suck Your Teeth" Cab to a blind tasting lunch which was attended by several restaurant owners, wine distributors, and the GM of Bastide, and it was one of the highest rated wines brought, many of which cost 3 figures. Sunce also gives a great discount to its members. We also belong to: Bella, because of the fantastic Zin and great events in their caves; Schramsberg, just because we love the sparkling wine; Martinelli because of their list, and the dream of being able to buy the Jackass Hill Zin; Grgich Hills, because we visited recently, love the wine, and I think we thought we were getting a reasonable discount; Michel-Schlumberger (great reds); and Armida, I have no idea why. Maybe because my girlfriend likes their bocce and their BBQ during events. I'm not so crazy about their wine, but it is a fun place.
