I'm making BM Cream of Three Crops and I'm trying to figure my efficency. The wiki doesn't have maximum potentials for flaked maize, or minute rice. Does anyone know where I could find these numbers?
According to BeerSmith, flaked corn is 1.037 and flaked rice (not sure about minute rice) is 1.032. It's also in the HBT Wiki. The info there looks like it came from BeerSmith too.
Palmer gives similar, albeit slightly different figures, in a table in How to Brew. Look in the Max PPG column.
