You guys just rocked my world. For 17 years I have been using 1.25 ratio and have been getting a mash efficiency between 94-98%. Then 5.5 gl of sparge water for a 5 gallon batch. Ferment in a 6 gallon carboy. Perhaps I'll bump up the mash water and lose some of the sparge water.
94-95% mash efficiency is insanely high. Conversion? Sure. Mash? Unlikely. Perhaps a difference of terminology is at play here?
can you elaborate?
Yeah, basically what they said. a 94%+ mash efficiency is EXTREMELY rare in my experience, I've only seen it one other time using a very fine crush, a recirculating mash and a very effective fly sparge system. How are you calculating this I wonder?
For definitions and such you can check out my blog post here http://pricelessbrewing.github.io/methods/Efficiency/
. Typical values are conversion: 88-94%, lauter 85-94% depending on sparge method and run off ratios, mash is usually 70-85%, and brewhouse is usually 70-85% for zero apparent kettle losses.
I go by Braukaisers definitions, so it may just be a difference of terminology. Some older texts for example use mash efficiency interchangably with conversion, and uses kettle efficiency to refer to mash efficiency etc etc.
