hi all. big mistake. i thought id insulate my fermenting bucket to bring the temp up a little.....you know whats coming. checked temp last night and was 35 degrees. no wonder it had stopped bubbling away. i was just over half way through fermenting when i did this and i know ive killed the yeast. so can i add new yeast and nutrient to get her going again? thank you for your time. cheers muggy
