Hey All. I am somewhat new to homebrewing. I have done 2 brews using ingredient kits and they both turned out quite well. Now, I want to brew from scratch and get a little creative. I found an amber ale recipe online and it seems pretty basic; just grain, malt, and hops. I bought some apple flavoring drops at my LHBS and I was told to grab an ounce of beer before bottling and slowly add drops until I like the taste, then scale up to 12oz from there. I was planning on bottling a few beers using these and then I thought I would try other things like cinnamon, vanilla, and combinations of all of those. So, my question is, how much cinnamon or vanilla do you use in a 12oz beer? Or should I use the same idea of adding bit by bit until taste?
