I'm brewing an Eggnog Stout in a few days, I have never brewed with spices before. I have cinnamon sticks, ground nutmeg, and vanilla beans. I was planning on adding them towards,the end of the boil (maybe 20 min). I've been told that it is good to add them at the whirlpool, but am unsure where I'm not using all ground spices. I know I can also add them or add more in the secondary. What are your thoughts and when do you or would you add them?
