Berkeley Bowl House Wines
I don't frequent Berkeley Bowl on a regular basis and haven't tried the house lable wines there. I do know a couple distributors who use the store as a place to drop odd lots of wines at deep discounts, so it could be a good place to pick up an interesting bottle of wine on the cheap.
I'll add some comments on tips (like I used to judge the $2.99 wine at Grocery Outlet) for buying house labels. Will move to the General Topics area.
