Hi, I hope for some advice about cooling my fermenters, as ambient temperature in Sydney is above fermentation temp during the day. I have been working on this and have some equipment assembled as follows:
- an insulated cupboard that tightly fits two 23L fermenters
- a beer chiller - it's like a fridge with a bath of water and supplies fluid at 1degC - used for beer at functions but you can pump any liquid through it
- one of those chinese thermostats that can handle both cooling and heating and keeps your temp within 1 degC
So the advice I need is how best to apply that cooling (and light globe for heating if necessary) to the cupboard. Eg, would you put a copper or stainless steel coil directly into the wort, wrap a pipe around the barrel, have a copper coil in the cupboard and a fan to blow air on it?
