Need some advice!I'm on to my third brew and went out to check the temperature of my beer to find my missus had knocked my heat pad out of the thermostat and went and plugged it back in the wall. She neglected to tell me this till I found it. Anyway, I had it at a nice 20C and found it at 37C, it's been like that for probably about a day. I used US05, can I just buy another packet and put that in there or should I just start again!?
