A few years ago I attended GABF and they had some sort of biergarten near the front. Jameson had given a bunch (20?) of breweries barrels to age beers in and they presented them all there, so my first thought was that this is an off-shoot of that. But, from the pic it does seem like Jameson is actually making the beer.. I'm not a fan of Jameson, but the beers there, at that time, were "meh" to me, despite be liking barrel aged beers. Maybe this is a yearly thing, but I only attended that one time.
