I can't figure out why my efficiency is so low so I'm looking for help.
Here's my setup.
10 gallon rubbermaid cooler
copper manifold with saw cuts every 1/4 inch.
Batch sparge
Usual mash thickness of 1.25qt/lb.
Usual mash weight of 13lb grain. (milled at Midwest, gap set at 030)
I do a mash, then add boil water for mash out. The mash out water equals what will be needed to collect half of the total wort. So, usually may mash out water is 5 qts.
I then sparge once more with the remaining water.
Example. Mash with 4 gallons of water for 60 minutes (verified conversion with iodine). Add 5 quarts boiling water. This brought the grain bed to 168f. Vorlauf then drain and collect 3.63 gallons. Add 3.63 gallons of 180 sparge water which brings the bed to 172. Vorlauf and drain to collect and additional 3.63 for a totol of 7.25.
Where am I going wrong?
