Kegerator for the fridge and chest freezer for controlled fermentation temps. This has really upped the quality of my HomeBrewing. I keep glasses and hops in the overhead freezer. It’s so nice to pull a draft into a frozen glass.
Ditto, you need a valve on the output. On recirculating, I just dump the line back into the top of the mash tun. Adjust the flow so there is an inch of water on top of the grain. The Keggle yielded 91% efficiency on last Sunday’s batch.
