I have a mash tun which is a cooler box with a stripped toilet line, which seems quite a popular approach (like in
I am not sure why, but it drains e.x.t.r.e.m.e.l.y slowly which I guess adds close to an extra hour to my brew process. It is also an hour of extra work as I have to move the grains around to get the pre-wort to drain out.
So, I am thinking of a variation on the BIAB approach: Instead of making a bag to go in boil pot (as per normal BIAB), why not make a bag that fits snugly into my cooler?
I will mash normally - put the strike water in the cooler, mix with the grains etc, but the cooler will have this new lining. When it comes to draining the wort I can just lift the bag up and open the drain of the cooler and let the wort flow out - no need for special valves.
The bag is effectively an over sized false bottom. Would this work? I see no reason why not.
I spent some time looking for this on the web, but can't find any examples. Perhaps I am using the wrong search terms?
