Alright so I was able to use my cooling system to make a Brithish Pale Ale. Fermented at 65°F then let it raise to 68°F for 5 days. Time had come to cold crash, and I was only able to cool it down to 50°F! Little disappointed until I thought into it more, now I'm still optimistic. So keep in mind that I only have water in the system right now, no glocol yet. I was keeping the water reservior at around 40°F so there was no danger of freezing up. I think when I add a gallon or two of glycol and crank it down to hopefully 20° or even 0°F then it will be able to crash a batch no problem. Got another ale coming out next and then a kolsch.
