Here's a photo of "These Elderberries Taste Like Elderberries" Pale Ale from Unknown Brewing Company.

It was alright, a decent pale ale with subtle hint of flavor from the elderberry flower. I drank two, but the second one only because I helped brew it.
What was weird is there was no mention of it on their Twitter or even on the draft board at the brewery, so the only folks ordering it were the 9 or so folks with us. The more I think about it, it was just kind of a weird, throwaway experience that they offered up for a silent auction benefit last fall but maybe didn't think all the way through and possibly didn't want to do anymore when it came down to it. In any case, its still kinda cool that a beer I helped make was available at an actual brewery (even if I only basically provided unskilled labor help). I also added it to Untappd.
