My old mashtun


This is what my old mashtun looks like. It is a small Thermos Weekend Sky Cooler with an internal volume of 28 liters. I suspect that this also includes the space beneath the lid. With this one I've been able to mash up to 7 kilos of malt. It has been serving me well.


The cooler did not have a built-in spigot, so I had to make a manifold myself out of copper pipes. It must be left in the mashtun throughout the mash, and once the mash is done tubing can be connected to the pipe sticking out of the mash. It is then easy to start a siphon. I usually vorlauf the first liter of wort, or so, before draining everything into the kettle.


The copper manifold is made out of 4 elbows, 1 tee and about 1.5 meters of straight copper piping cut into smaller pieces. All the pieces are connected with teflon tape. I also used a hammer to tighten the connections so that they don't come loose too easily. It would suck if the manifold fell apart in the mash - fortunately that hasn't happened.


To be able to extract the wort I've cut small slots into the manifold with a hacksaw. There's about 1 cm between each slot. Creating a manifold like this actually quite straightforward.
