That said, I'd go to Healdsburg instead and focus on Dry Creek Valley. Or even up to the Anderson Valley, love what some of the wineries up there are doing, particularly Tolouse, Philips Hill, Breggo...I prefer the pace in those areas to Napa.
Can I go with you the next time you go?
This is great advice. Esp. if you like Zinfandel--the Dry Creek Valley is heaven.
Up in the Anderson Valley, the operations are smaller and humbler. You're more likely to find yourself talking to owners and winemakers instead of young staff in logo'd polo shirts. Like you imagine it; like it used to be.
