Since walmart has these for under 40 bucks I was going to get one and do a MLT conversion. I do mainly 5 gallon batchs would there be too much headspace using a 70 qt cooler causing me to lose temp quicker?
I have one and unless its super cold outside I dont lose any temp. Make sure you preheat the MLT well before mashing and if it is really cold wrap a warm blanket around it while mashing
I just got an Igloo 120 qt from Wal-Mart on Wednesday (to upgrade from my Rubbermaid 48 qt) because I needed the room for a 10-gallon Bock (30 lb +/- grain bill!)
Nice I am brewing outside in the north east, so I am just going to use some foam insulation board and a blinket, hopefully that holds it. Now to get the parts.
