What is the best way to insulate a mash tun? I have just fitted a tap to a cool box i was given, put around 18 litres of water in (60 degrees c ) then checked the temp after 90 mins, i had lost 8 degrees. Ive insulated the lid with two layers of foam camping mat and tin foil. I re tested and am losing approx 4 degrees over 90 mins. Is it a fair test with just water?
