about 3+ weeks ago i did 2 ag brews on consecutive days. the 1st went into ferment fridge and is now cc'ing. the 2nd, i put into a spare cube, with some co2 on top, awaiting a fermentor & fridge space (both pils). being slack, it has been sitting on the balcony, where the temp has been around 15 - 20'c. today was warm, around 30'c. i noticed the cube had foamed up a bit, and loosening the cap released some gas. i wasnt expectng this, as had sanistised the cube. the $64 question is should i try to ferment it in the next few days or is it contaminated & should be chucked ?
