My father and I are just adventuring into all-grain using the BIAB method.
I have an old 30L (8gal) ice cooler that I was planning to repurpose as a mash tun. I’ve been experimenting with just water to see how well it holds the heat, but it drops 4.9 degrees Celsius (~8.8 F) over 1 hour with 22L of water @ 65°C/149°F. Ambient temperature was 22°C/72°F.
That sounds like a weak performance, but I am not sure. How much should I expect the temperature to drop in a cheap ice cooler?
Right now we are working on insulating the cooler with styrofoam sheets, but it I think it kind of defeats the purpose of using an ice cooler in the first place.
