Notes

Steam/ boil rice in grain basket with 24qt water for 15/20mins until done. Add remaining 10 qt strike water and brewing salts and bring up to strike temp. Once salts have dissolved, pull off 6 qt of water to reserve for sparge.

Very vigorous boil to yield good head retention.

Or lager yeast at 70F under 5-10 psi for 1-2 weeks.

Transfer to secondary with finings and cold crash and lager around 33 - 36 F for at least 2 weeks.
