I signed up to the Kickstarter for the Brew Jacket. It should ship any time. It is a heat pump that fits inside a Better Bottle or bucket. It takes up the space of a carboy or bucket, unlike a refrigerator. I will review it once I get it up and running. It is supposed to reach lager temps. It comes with a wrap/jacket to help maintain the temps. I will use it mostly to keep my temps in the mid 60s.....A little lower for Kolsch and Cal Commons.
