Bringing this one back to life. I've done three straight brews now with just a 30 minute mash, no mashout. Brew in a bag method.
My efficiencies have been 65, 70, 70. The 65 was with wheat. These were all between .045-.065 beers.
My best efficiency with a 60 minute mash was 78. While brewing is an enjoyable process for me, it doesn't need to be any longer than it has to. I'll trade a couple bucks of grain for an extra half hour!
