I'm interested in starting to make my own bitters for my home bar. Other than using various bitters in my drinks I don't know the first thing about how to create the base flavors to combine into a finished bitter or even what base alcohol to use. Extra points for photos documenting some of the steps to create my first set of bitters!
EDIT: I'm looking for a good entry point for making bitters at home, maybe $100 investment, flavors that are different than the common brands. I tend to like to make pisco sours and classic old fashioned or el presidente drinks but I explore quite a bit. I'm curious if citrus is a good place to start or should I start around some herbal flavors?
