1979 - Omission Lager by Omission Brewing Co., Portland OR.
I'm a former home brewer who had to give it up due to a gluten intolerance. All the gluten free beers I tried where "meh" at best. Last night I took a chance on one of the "gluten reduced" beers (real beer treated with an enzyme to remove most of the gluten). Wow, this one actually tastes like beer and so far no gluten reaction. Now to track down their PA, IPA and other brands in this category. Happy, happy.
