the wife and I have been doing a lot of cold brew coffee/tea lately. is this possible with beer? just interested.....thanks!
You are asking if you can brew a beer without heating it? Heat is key for enzyme activity, protein coagulation, sanitation of the wort, hop isomerization etc. You can certainly add cold brewed coffee to beer (or use beer as the medium for extracting coffee aromatics on the cold side). You can also do cold steeping of dark specialty malts, but the liquid would have to be boiled to kill any Lactobacillus living on the grain before the main fermentation.
still would need a way to isomerize the hops and pray to the gods of beer that you didn't take anything with the extract into the bucket.
Prehopped malt extract. Jamil did a beer like this, apparently it turned out very well. Just mixed extract with water and popped in the yeast.
