I've read most of this and am trying to get my efficiency up to a decent range. Beersmith has been reporting my efficiency in the low 60s for a couple years (per Beersmith. (I have my mill gap at minimum, Denny).
Today I tried using Braukaiser's efficiency worksheet and got some encouraging results, some confusing ones.
The spreadsheet reported my mash efficiency at 59% (first runnings only), but my efficiency into the kettle at 84%. I like the second number
. The difference was the sparge. I mashed in at 3.9G for 9.75 lbs of grain (ratio:1.5). Sparge was 3.5G.
BeerSmith v3 on the other hand reported 81% mash eff. and 58% measured BH eff.
A couple questions - why are the two BK numbers so far off? And of course, why are Braukaiser and BeerSmith so different?
