a 5 gallon beverage cooler will handle approximately 10-11 pounds of grain, a 10 gallon will handle roughly 20lbs and this is with a standard single infusion mash and batch sparge or fly sparge.
Summing It All UpStrike the grain between 165-170°f to mash at 150-155°f. Do this for an hour. Empty the mash tun and rinse the grains with the mash water once. Strike with sparge water at 180°f. Add enough sparge water so that the total volume of first runnings and sparge will be between 6-6.5 gallons.May 30, 2019
