The brewing system

This is the mash tun. I removed the spigot and installed a 1/2" ball valve with a quick connect and a stainless mesh. I added a valve at the top for the wort return. The silicone tubing will rest on top of the grain bed. This will also be used for sparging.

The brewing system

I'm building a recirculating infusion mash system to brew beer using all grain. The main component of this system is a heat tube, to maintain mashing temperatures while the pump circulates the wort through the grains. I bought some 1 1/4" copper tubing and some copper fittings to allow me to use a hot water heater element and flow the wort past it. I added a thermowell to monitor the temp as it passes back out to the mash tun.
