Napa Valley Christmas/NYE

Looking to travel to Napa for the first time over the winter break. Does anyone have experience with traveling over the holidays whether it’s Christmas or New Year’s Eve?
Are wineries still open during the holidays?
We’re going for our first time, so if you guys have any recommendations for hotels and restaurants, I would appreciate that.
Also, are there any wineries that do barrel tastings?


ditto. would love some input here.
