I am working on a recipe for a Cinnamon Hazelnut stout but I haven't done a lot with spices or extracts yet. I had a holiday beer last year that I used a touch too much all-spice and it was way overpowering so I am being a little more cautious this time. Anyone have an idea about how much ground cinnamon would be good for a 5 gal all-grain batch? Also I will get Hazelnut extract so looking for a rough estimate on how many drops would be good for the same batch. I assume the best way would be to add this to taste right before bottling? Thanks!
