So by increasing my ability to brew 15 gallon batches I now have a stainless steel 15.5 gallon keg as a mash tun as opposed to my 10 gallon cooler. My three tier system is setup with a burner on all three tiers. What is the benefit to doing step mashes as opposed to single infusion mashes. Will I really notice any change in quality of beer? Typically brewing IPA'S, stouts and porters. Basically will it be more of a pain in the ass to add heat and try to hit temps vs drinking a beer while it sits there for an hour. What do I gain in the end??
