So, while cleaning out my cellar, I found my missing fermentor, filled with, (according to my note), an Altbier made back in september 2022, made of pilsner, munich dark, cara munich dark and roasted barley malt, with 70g Northern Brewer hops. OG was supposed to be 1.049. When i peeked inside, there was no sign of mold, there was no weird smell coming out of it. Is it still drinkable? My cellar is at a constant 15°c (58/59°f) Or should I dump it?
