It seems like it's just hitting the area. I saw some at Bay View Liquors this weekend, and I'm fairly sure I saw some at Craft Beer Cellar yesterday.
Craft Beer Cellar in Belmont had some today when I was there. Had a bottle the other night, still a tasty brew.
I was under the impression this is released in the Fall ? Have a couple bottles from the last time I bought it in the cellar, very nice beer.
