I've cellared my carbing/conditioning beer (around 65 degrees) and I've stored it in my kitchen pantry (around 70 degrees.) I find it's faster to store it in the 70's but I haven't really noticed if it tastes better conditioning in slightly colder temps.
My next batch maybe I'll split it up and put half in the basement and half in the pantry and see if there's a difference. I played with the idea that when carbing you're adding more sugar thus starting a mini re-fermentation. So maybe I'll split the next batch into thirds... a third in the basement, a third in the pantry and a third in the basement for a week and then move it upstairs to the pantry since fermentation temps are better in the basement. Maybe there will be a difference? There might be I suppose but probably not enough to notice.
I can't wait to start kegging.... :rockin:
