I use that converted keg that some of you must have seen already for my BIAB .... wrap that baby in a thick sleeping bag & she hardly drops.
I did a brew on Sunday ... wrapped her up and only dropped from 64.4 to 63.5 in a 90min mash... it dropped to 63.8ºC within the first 30min, but basically stayed there for the other 60min. I removed the sleeping bag on 80min to start heating it up for a mash-out @ 75.4ºC (10min)
I've tried blankets before, but the sleeping bag is a winner.![]()
Old sleeping bags really works wonders. I have a -2ºC/-4ºC sleeping bag that I used and also minimal temp change. Also use those itchy blankets (quilt) that you can buy at a pep or game.
