More Mash Tun Progress

I’ve managed to make some more progress on the mash tun. Over the past couple of nights I’ve grabbed half an hour when everyone else has gone to bed and started to insulate it.

My insulation of choice is aluminium-lined thermal wrap insulation, the sort of thing you can buy a big roll of from DIY shops to wrap up boilers and such. It’s not the worst job in the world, but it’s not the easiest either. Let’s just say if I were to give one as a present now, I’d definitely be tying a ribbon around it rather than wrapping it.

After a lot of frustration and furious cutting and sticking, I’ve now got it to the stage where I’d be happy to use it, although I think I’ll be adding one more layer just to make sure. The whole thing is taped up with overlapping pieces of duct tape which should mean it keeps a nice waterproof seal and stops yucky, sticky wort getting between the insulation and the bin.

Mast tun all wrapped up warm, one more layer to go on. the tap needs tidying-up too.

Once the last layer goes on I’m going to fit the tap and fill it with water to test for leaks again, and then I’ll half-fill it with hot water and do a test to see how well it holds temperature.

I’m getting there slowly.
