update: Everything went pretty well on brew day. I added 3.5 lbs of roasted yams with the mash in grain bags. I added the spiced and vanilla bean with 2 minutes left in the boil. And 2 oz of golding at 30 minutes.
I came up with an oddly low og reading, twice. I blame it on topping off with water and not getting it mixed up well enough. I got two different, low reading before i said to hell with it, it is what it is and threw on the airlock. I need to figure that one out. It's currently bubbling away. I'll put it into secondary next weekend with a cup of maple syrup. Hopefully all is well.
I assume with a big beer like this it will take a little longer to condition in the bottle and carbonate properly? I was hoping to have a few for thanksgiving, but they may be better saved for christmas perhaps? Thanks for all the advice, i'll keep you updated on how it comes out.
