Did you sparge?
What kind of wheat did you use?
I had an Old Rasputen with my brother after brewing Monday... and it was amazing!
I did indeed sparge (double batch sparge), as you should with any all grain beer. This one is tricky, as it has a lot of grain, and thus you will not have a lot of water to sparge with after you do the mash.
With this much grain efficiency tends to go down. I collect more wort than normal and do a long boil, adding in wort as it boils down and start my hops addition once all the wort is in the pot.
Mash with about 4 gallons of water, make sure your strike water is around 170F with this mash thickness. Hopefully this will then get you to the temp you need, if you are cold by a couple degrees (152F instead of 154F) it still will be fine.
Boil up about 5 gallons for sparging. Add as much as you need to get the grain bed temp up to 170F, stir like mad, and then drain. The rest of the water should have cooled off a lot by then, and just pour it all in for the second batch sparge. Stir like mad again. Drain. Proceed as normal.
For the wheat I just used American white wheat as far as I can recall (I don't have my brew book in front of me). If I am wrong I will let you know, will check after work today.
Old Rasputen is a amazing brew. This one has a lot of similarities to it, but does not have the anise note. I actually prefer it without.
Make sure you do the starter! If you don't have a stir plate then make a bigger one, the yeast has a LOT of work to do! let me know how the brew goes!
