Yes, Steve. It was from Leo's and they may have a problem with their lines. If it's still on tap, I'm going to ask for a sample to consume in the store and see if I get the same reaction. If not, maybe it was the growler itself which I rather doubt. There's only one way to find out!
That wasn't meant to be a diss on Leo's -- I just don't know many places to get GI growler fills! I enjoyed my first sojourn there Friday night before the Brixie's barrel-aged madness; as I was driving my city friends back to the train station after the Brix we detoured to Leo's so they could pick up some barrel-aged Firestone-Walker stuff that I'd noticed.
