I have rather low efficiency (~55%) and it's been offered that a proper mash-out might help. Am I to raise the temp to 170 through infusion, decoction, or both?
For the Special Bitter I'm brewing tomorrow I'll have a mash of 16.63 qts @ 149F. To raise that to 168 I'd have to add 19 qts of boiling water! If I add only 1 gallon of boiling water to my 16.63 qt 149F mash all I've done is raise the mash temp to 154F and that hardly seems worthwhile. I'm confused....
