+1 to the STC-1000 temp controller. I've built 4 now for $30 a piece (if you already have your own spare power cable). I have mine strapped to a keg / carboy with bungee cords just like Rustym has his in the pictures above. I just use a washcloth folded over a couple times as the insulator rather than foam. This set up allows me to perfectly control my fermenting / lagering / serving temps within 1 degree.

But of course, the chest freezer or upright fridge is sold separately!

Good stuff.

I have gone for a waterbath setup for actual control. I have a larder which is about 10-16C during the autumn/winter, the idea on my next batch is the put the fermenter in the water bath with an aquarium heater and stick the whole lot in the larder.

For the water bath I just bought a 72L rubble bucket.

Works pretty awesome. Here are my temps in real time:


This is obviously the hi-tech approach

I do something like this, but well eventually upgrade to a thermowell. I use heat so brew primarly in the fall, winter and spring
