Hello All,
I am a new BIAB brewer. I have a hard time maintaining mash temp. I wrap with two layers of Reflectix and sometimes throw a sleeping bag over that and still have seen temps drop up to 5-6 degrees. My long term plan is to go E-BIAB so won’t be much of a problem then. Until then I have heard of people doing their BIAB mash in an igloo cooler. I may try this but want to know what you think about proper size. I mainly do 2.5 batches so I can brew more. I do a 5 gallon every now and then just to have a good go to on hand. Was thinking 10 gallon igloo but was not sure if that would be to big with to much headspace for the smaller mashes? I have also heard of people putting aluminum foil over the top of mash to help keep heat from evaporating if there is a lot of head space. Thoughts?
