Hello all, New to the brewing game but following some instructions from someone more experienced. Things going well however on this batch, when I thought I was putting cold water into the barrel, it was in fact warm water, quite warm! Oops It wasn’t until I had added the yeast and closed everything up that I realised the temp was in excess of 40 degrees. Which remained the case for a few hours until it cooled. From what I have read it’s likely I have killed the yeast. Is this the case? Secondly, if I have killed the yeast, can I simply add another packet to save me throwing this batch out? Will the dead yeast cause any issues with the beer / flavour etc? Thanks in advance.
