Ok.. so after some more aging I pulled a pint and the diacetyl is gone.. but this beer is awful. I'm terrible at describing it, but it's not at all what I thought. Seems like some weird esters from the yeast, and the hops don't smell good at all. It has to have something to do with finishing out so low.. I'm wondering if I didn't get an infection of some sort.
This thing is 6 weeks old, and I don't need the keg yet so I'm going to leave it be, but if it doesn't get any better I may dump it. There is no way I would get through 5 gallons of this. Would I be better to drag it out, and let the keg warm up.. or keep it in the fridge?
I'm sure the recipe is great, but I think I just screwed it up. I have never had a California Common before, but after reading descriptions I don't seem to be anywhere close.
