Brewed my second batch of brew using a coppers kit, pitched my yeast at 25 degrees which i know is a bit high, its been 48 hours since and there still seems to be no fermentation going on. I wouldnt think the yeast would be affected much by this pitching temp. The only other reason i could see is i used a brew enhancer 2 kit from coopers but it was set hard as concrete so i made sure to get rid of all clumps when i mixed it with the can wort. I dont see where i went wrong im just wondering if its normal for fermentation signs to take a little longer in some cases but 2 days seems long enough to me.
