Yes, it was a club brew we did. 1.090 beer. Just way too big for the mash tun. Normally I am much higher, but big beers do take a hit. It was actually one of the earlier beers I did on the system though, so maybe if I did it now it wouldn't be so low. I've done a lot to the system since then. Hmmm, maybe I should give it another try?
