I've got a system set up with a 10 gallon rectangular cooler for 6 gallon batch mashing. My brew kettle is a converted 1/2 keg. I want to move up from 6 gal. to 10 gal. batches, and I think the brew kettle will be fine, but I need a bigger mash tun. It's a RIMS system, no need for direct heat, so I'd like to stick with a cooler for a mash tun.
Any suggestions for a good cooler to buy? Thanks,
