Newbie here. I have batch 2 in a secondary right now, but with a recent warmup here in Cali, I noticed my fermenter running around 70 (taken with a stick on.) I’m wondering, how does everyone keep their fermenters in the 60’s during the summer months?
I have an aquarium chiller in the garage from when I had a saltwater aquarium. (I was mostly just good at killing fish, so I gave up that hobby. I like beer more, anyways.) Has anyone tried anything like that?
