My friends want it all when they come to the wine country. They want to visit all their favorite places but grumble when they’re left with little or no time to discover new things. They want to try limited production wines, brands and varietals their friends haven't heard of, but don’t want to spend the extra bucks on random picks at restaurants or drive to the far reaches of the valley. In the past, my answer to their plights was simply: "Visit more often and stay longer." But there is another solution: Winery collectives and downtown tasting rooms.
