My missus brewed beer for years, will have an ask and see what you need
Pretty sure she used heated mats and I made a contraption to cool the brew down. Consisted of coiled copper pipe and hose pipe that connected to the cold water tap and was dunked in the mash
Also got some big cylindrical airtight containers that can be pressurised for keeping the brew in, loads of other stuff too
Think some or all could be for sale because due to medical reasons I can no longer drink the produce (probably drunk too much of it i'm ashamed to say)
Still got one of the good beer kits left, Brupaks I think, definitely one of the malt type and none of that sugar homebrew taste crap
There was at one time an annual homebrew show, been to a few, but think it might not be running anymore. Was a magazine too and we have loads of books on the subject as well
