Ok, I did my first ever Hefeweizen yesterday, it has been about 16 hours since I put it away to ferment. It has not started to do anything at all, not even a little bitty bubble. So, I think I may have destroyed it by adding ice directly to cool it quickly, I added the 2nd bag of ice at about 104 degrees it quickly went to 65 degrees, I put it in the fermenting pale added the yeast but here we are the following day and nothing. What do you all think, did I blow it?
