Sounds pretty yummy to me!
Want to know my Yule Ale secret? I don't use spices until I put the beer in the Crock-pot to "mull". I just make a nice, strong Brown Ale on the sweet side of balanced. Pour some into the Crock-pot to warm, along with the spices, about a half an hour before company shows up. Yum!
But the way it's written, your recipe is gonna rock!
