I finally have this carbed in the keg and the taste reminds me of magnificent. When I first tasted it in the primary I thought it was a little bland (brewed exactly as written). It was still a great beer, but it needed some more flavor. Then I did the following additions to the recipe:
I brought about 2 cups of water to a boil, then threw in two cut madagascar vanilla beans, the original amount of spices (in addition to what was added to the boil kettle), a little extra cinnamon on top of that, and 8 oz maltodextrin. I let that mixture boil for 1 minute, cooled then dumped into the fermenter.
Then I let it sit for two more weeks, and crash cooled with gelatin. I don't normally do the gelatin thing, but the wy1450 just refused to flocculate and had a yeast bite that wouldn't go away.
I also racked a gallon of this into a jug and added some Jolly Pumpkin dregs. I will be drinking the funky batch at the same time I'm drinking the re-brew of this recipe next year...stay tuned for that episode! Thanks KingBrian!
