For one, a "Mitsuko's Vineyard" chardonnay from Clos Pegase. Plus the artwork is the best in the valley. Vist the caves. In Sonoma I like DeLoach in Santa Rosa, ask for the OFS Chardonnay. My friend Tom Burgess at Burgess Vineyards (St. Helena, but up in the mountains) always makes lovely buttery whites........I have not visited him in 2 years, don't know what he's up to now but I'm certain it's delicious!
