If it's worth doing, it's worth overdoing
I'd like to make a 10% ABV stout. At the efficiency I get with my cooler MLT, I'll need 20.5 lbs of grain. Mashing at 1 qt/lb, first runnings would be 3 gallons. Batch sparging with .75 qt/lb twice will give me another 7.68 gallons. This will give me 10.7 gallons in the kettle for a 6 gallon batch! Is it normal to need to boil for almost 5 hours for a high ABV beer?
