The Study Wine Bar is open 4 days a week, Thurs. & Fri. 5-9 Sat. & Sun. from 1-7
We are more than happy to stay open later should business merit this, however it's always best to call if you're considering bouncing in on the later side: 510.295.5442
Also, please note, we are a working winery, from time to time, especially during harvest, the bar can serve as an overflow area, but there's always room for guests.
