So I'm about 10 batches into my home brewing life, doing All Grain now and its come out well 9/10 times but I'm fermenting at too high of a temperature so I'm sure it could be better. Issue is I live in a 1 bdrm apartment so I don't have a cellar or space for another fridge. Are there any thoughts on how to keep temps down on a carboy w/o buying a fridge or maintaining a non-stop ice bath for a few weeks? It's pretty hard to drop the temps in my apartment below 25 deg C (77 F). Thanks for the input!
