Kmart does one pretty cheap. Probably not the best insulation but a yoga mat will fix that...Could it also be worth picking up a cheap esky to use a HLT for sparge water (boil some water in the urn, then transfer to HLT before starting the mash process) ? Seen a few similar to this for $20/$30 on facebook - https://www.bunnings.com.au/esky-15l-blue-keg_p3240514
How have you been finding this system? I have half a foot in all grain and have been debating between saving for a Guten system, or just getting a boiler and modifying an old esky for a mash tun. Though the jacket, false bottom and BIAB look tempting to reduce the vessel numbers and work load.
Thanks for that information. Super useful. I have ordered a DigiBoil Urn, a false bottom and a grain bag so looking forward to getting going on a full BIAB system.I’ve been doing BIAB in a crown urn and it’s stoopid easy and I make beers People seem really happy with. With wrapping the urn in a camping mat and some blankets it’ll hold temperature for 90 mins without any problem.
With cold crash with some gelatin my beers are always clear so I don’t think you are going to get much benefit out of the recirc. If you are hung up on efficiency then buy an extra 250g of grain.
With BIAB there No stuck sparges and cleaning is a doddle and less room for infections.
The only advantage I see with the pumped systems is better temp control on stepped mashes, but It’s never looked like a worthwhile payback for me.
I think you get better results in concentrating on the fermenting and packaging side.
ive got a brew tech brew bucket and it’s fantastic. but if you don’t have a fridge and temp controller I think you would be better off doing that and not worrying too much about the stainless yet. If you have a fridge then the stainless makes sense.
I’d get a couple of flasks and a stir plate to get a healthy yeast pitch. I’ve got half a dozen mason jars in the back of the fridge with different yeasts so that quickly pays for itself.
Kegs really are the next best and I’d much rather do that then spend money on mashing equipment.
less exposure to oxygen, less risk of infection and a heap less time spent through the process.
