I use promash, and it has been telling me my eff is 57%...OK. Las 4 batches have been coming in arount that number.
So I asked promash to scale up the ingredients for the Ed Wort's HPA recipe, assuming 57% mash eff. (I called it HPA 57)..Pro Mash predicted 1052..My gravity was 1054 - it was like magic.
I can live with 57% eff, as long as my results are as consistent with what Pro Mash reports. Glad I am not trying to do this scaling manually.
I wish there were updates to Promash..
