Napa and Sonoma Valley are the premier wine growing regions in California, make that USA. They have vast inventory, just go to a winery one day stop for wine tasting and tour.
The image is bit blurry, but those are all bottles of wine (well technically these are champagnes, or sparkling wines).
That's the hubs and I wine tasting in Sonoma. Bottles of wine infront of us and more bottles of wine behind us.
