If you haven't had a chance to check out the dedicated wine shop opened by the Compline team, you should definitely put it on your short list. I really love the vibe of the space - minimalistic, with a huge mural showing many of the world's wine regions, and the centerpiece record player that's always spinning. It's a great place to duck in out of the brutal summertime Napa heat to grab a glass or two of some exceptional wines. They offer a number of wines by the glass, ranging in price from $14-25/glass - it's a pretty broad selection with something for everyone. Additionally, they offer some flights if you want to try a range of different wines. Perhaps the best value though is to pick up a bottle from their selection and enjoy it in the shop for a $30 corkage (though I heard this may decrease to $15 to match the restaurant). The selection is absolutely massive and while I did see some very expensive, well recognized labels on the shelf (Ponsot, for example), their selection tends to focus on smaller producers and even more obscure varietals, which is great! You may find some bottles at other shops a few dollars cheaper, but overall, the pricing is very reasonable.
If you're looking for a special bottle to take home or looking to kill some time before a dinner reservation, definitely add the wine shop to your list.
