Mash Tun Switch

After doing a couple of dozen batches on my new sculpture and fighting with drifting mash temperatures most of the time I finally decided to swap back over to an insulated Gott cooler for my mash tun.

What a difference. I no longer had to pay attention to the mash temp, mess with pumps for my HERMS, run the stir motor on the hot liquor tank, or worry about grainbed compaction. Despite cool evening air temps the mash held within a degree over the course of the hour.

I really haven’t found a downside of this approach other than it means I have a surplus Blichmann Boilermaker mash tun for now. I’m going to run this way for a while and see if I can notice a difference in consistency on my beers and simplification on my brew day.

    Hey Dave – I have done 3 batches on my replica of your stand so far – all with 2 of the 10 gallon gott coolers + pump as trial batches. The coolers work great as you know- but now that I am installing a single burner on the middle tier, I am concerned that the heat from the burner will melt or compromise the HLT (bottom) and MT on the top – are you seeing any issues with heat affecting the mash tun on the top tier yet with this setup?
    Thanks again for the plans/info – it works and looks great! (Locking casters are next on the agenda…)

    I haven’t had any issues but then I use shields on the burners that help direct the heat upwards. Check them out at ( There should be enough space between the coolers and the heat source but it’s probably best to keep an eye on things just in case.
