I'll have to look for that one. I didn't see it the last time I stopped in a TJ.
I know Firestone-Walker makes some of the Trader Joe's beers. The Mission St. ones, I think. And like somebody said, Unibroue makes their holiday vintage beers.
All of their store brand beers are no joke and super good deals. They get legit breweries to make the beer for them.
I also like their Botswain line. Especially the HLV (heavy lift vessel) ale. Not sure what style that one is, but something british. The double IPA isn't my favorite, though. I think that line is brewed by Minhas Brewing.
