1lb enriched white rice (rinsed until the water was clear to remove the vitamins)
I did a 30 minute protein rest (for the rice) and a 60 minute mash with two 1.75 gallon sparges and a 75 minute boil and ended up with 6.33 gallons of 1.047 gravity wort.
I just bottled my 6 gallon version last night. It tasted pretty damn good for being warm and flat.
The gravity at bottling ended up being 1.010 with White Labs California Ale Yeast (78% attenuation). I expected a little bit better attenuation since there is 3 pounds of adjunct grains, but the ABV is slightly higher than the original Co3C recipe.
It was still very cloudy after 18 days in primary. I'm guessing that will clear up pretty well in the bottles.
