There are several threads here that discuss it, I would link em, but I'm on my phone. Grain bill is basically 94% 2row, 3% C120, and 3% Victory. There is a little disagreement on how to hop exactly, but I would think that the bittering is done by Columbus and flavor/aroma by the centennial and simcoe, not the other way around as some have suggested. If you search maharaja there will be a thread where a guy close to the bottom of the first page (or maybe the second) says that he got his recipe straight from Avery. It looks like what I would imagine, and was posted on several other sites. Good luck! It is a great brew.
