At least I'm consistent. For the past five or so all grain batches I've been calculating my mash efficiency in the fifties. My last two were the best at 59%. I hear others obtaining. 80%. So I'm I calculating or measuring wrong? Or is my technique wrong?
Example from yesterdays brew:
Mashed 11.5lb grain in 32 quart cooler/mash tun with 4 gallon of strike water at 164°F, resting at 153°F for 60 min, stirring every 15 minutes with only a drop of 4 degrees by the end of the mash.
First running collected approx 3 gallons with SG 1.071 and pH 5.0. Sparked with 4.5 gallons water at 168°F stirred and rested for fifteen minutes. Drained and collected 6.5 gallons of wort total with SG 1.040.
I believe the correct calculation is:
Total wort collected X OG / total grain bill.
In my case 59%.
Can someone help me with this...feel like I'm missing something.
