Notes

Below are the steps I used for cooking the rice and incorporating it into the mash:

RINSE RICE VERY WELL!
Bring 3 gallons of distilled water to a boil in the kettle. Using the steel mesh basket, add all the rice to the boil and reduce heat to a simmer. Cover and cook the rice for 30 minutes (or longer, if necessary). After rice is cooked, remove the basket and top off water to reach 6.58 gallons. Heat/cool as required to reach a mash temp of 147°F. Remember to factor the cooked rice temperature when calculating a strike temperature!
Check pH before adding lactic acid. The rice doesn't seem to factor into the water calculator and my last batch ended up not needing any lactic acid.
Rice hulls are highly recommended during the mash.
On my last batch the mash was really thick after blending the rice and grains. It may not be necessary, but I used 30 drops (approximately 1/4 teaspoon) of Glucabuster to aid with recirculation. It helped a ton.
Boil time for the batch is only 30 minutes, however that may have to be extended based on water volume. My pre-boil volume was much higher than anticipated last time.
Pressure ferment at 68°F @ 15psi.
