Here. This was a gluten test done on Sam Adams Boston Lager only but it was negative. None of the beer Sam Adams makes has gluten ingredients. Not one that I am aware of. Of course, as often as new beers are introduced, that might not be accurate anymore. Most craft beers are the same. You've been misinformed.
