From what I can tell, this will be a bottled release of a gluten-free beer, both a Pale Ale, and Lager Beer. Information popped up over at 'GlutenFreePortland.org'.
I don't think I have even tried a gluten-free beer. I don't need to because I have been checked for a gluten intolerance and it came back negative. I actually think many claim to need gluten-free foods and drinks when in fact, they are not even intolerant to it. I do think though that these will be the first gluten-free beers I will try. I look forward to seeing how good they may be. Something tells me they will be.

I'll create a follow-up post once I attend the event.
