Notes

Forbidden Black Rice (Lotus Foods - Item #10270S) - Rice used unmilled. Clean with cool (room temp) water. Bring 36 gallons of water to boil and transfer to Mash Tun with Black Rice and let sit sealed for 60 mins. Begin adding remaining Strike water at appropriate temp to reduce mash temp to less than 149 degrees (Amylo 300 max active temp) and a pH range of 5.4 (min) to 5.6 (max). 145 - 147 degrees recommended. Begin incorporating remaining grain bill once strike temp is within range. (Added Amylo 300 for full 60 min Mash rest).

Note 1: Our Mash temp finished at 148.6 degrees and reduced to 146 degrees over the hour Mash sach rest. PH was tested and range was 5.46 pH.

Note 2: Strike water for rice infused water reduced to approx 188 degrees over 60 mins. Added 30 galls of 130 degree water and 30 gals of 150 degree water to reach 148 degree water for final mash temp.

Note 3: Amylo 300 added at 300 ml rate at start of Mash, and reached 10.4 degrees Plato (post boil test was 11 and Ferm check was 10.4). Unknown if higher Amylo 300 pitch rate would secure higher ABV, but dryness may be a factor (brut style beer?)

Note 4: Rice Conversion - 88 lbs of rice; manufacturer calls for 1.75 cups of water per 1 cup of rice or 23 gallons of water for (88 lbs) of rice. Allowing for additional apporox 27 gallons to lower viscosity and fill mash tun void (approx 10 gals in our brew vessel)
