\"\"<\/a><\/p>\n

My new brewing setup. A nice large stainless steel urn with a dual element, and a cooler box with a filter that used to be a braided hose<\/a> and a tap.<\/p>\n

The box under the urn is a PID controller so that I can (in theory*) dial the temperature, have a homebrew<\/a>, and have water at the right temperature on tap.<\/p>\n

\"\"<\/a><\/p>\n

It’s not going to win a panel wiring contest, but it works. The PID doesn’t have the switching capacity, so there’s a solid state relay. I also wired diodes to send the positive part of the AC to the one element and the negative part of the AC to the other element to spread the heat.<\/p>\n

\"\"<\/a><\/p>\n

The switch controlling whether the diodes are in-circuit or not comes from the junkbox. Been a while since one could buy something useful for R3.45.<\/p>\n

\"\"<\/a><\/p>\n

Grain in the cooler (this is 6 kilos of pilsner, on Saturday), add the water, let it be for about an hour…<\/p>\n

\"\"<\/a><\/p>\n

..and drain the good stuff (this is Sunday’s brew, an IPA).<\/p>\n

\"\"<\/a><\/p>\n

The pilsner<\/a> is all-grain, which means that you end up with quite a lot of liquid to boil.<\/p>\n

That’s the next step. The urn, on low, should be able to boil the wort as well. If not, I need to get a 30 liter+ pot, I have quite a few gas burners.<\/p>\n

Good news is that both brews started bubbling easily (I added Servomyces to both and DAP to the IPA). The pilsner is my first all-grain and my first lager — I’m using ice to keep it cool.<\/p>\n

* The water coming out the tap seems about 5C too cold. Some calibration required, looks like.<\/p>\n
