Maybe I'm spoiled growing up near all the great wine regions of California but the wine here to me was totally uninspired. The Chardonnay tasted like something out of a box and the sparkling had almost no bubbles. The only wine remotely interesting was the Zinfandel made with Lodi grapes. I was also disappointed they didn't have tasting notes from the wine maker with vintages, grape sources, etc. which is pretty standard at a winery in my experience.
The space is great, nice location and well thought-out layout. And I bet a bottling party would be fun.
