I have a 20 gallon pot. I have a roll of duct insulation that I cut to length and I wrap it around the pot and hold snug with a bungee cord. I also brew in West Central Florida so not many of my brew days are cold.
Brew Bag. Absolutely love it. I can brew a 5 gallon batch and from mash in to clean-up be done in about 3-4 hours. My guild keeps trying to get me to go true all grain, but I love the ease of BIAB.
