I was chatting with a buddy last night about airating with an oxygen system and he said something that peaked my interest. I assume that the oxygen bottles you buy at the hardware store for this system is compressed O. When compressed gas is released, it's very cold.
My question, could you use a oxygen system to say reduce your wort temp from 120-130 down to pitching temp?
