This place was exactly what I was looking for and didn't even know it. I bartend at Taco Y Taco and am experimenting with making my own bitters. I was able to find everything I needed sans Cinchoa Bark, which is where Quinine is obtained from, but I was able to find that by the oz. on Amazon but for cheaper here: http://www.pennherb.com/6668?nomo=1
I went in expecting to buy at least an oz. of everything i needed but was pleasantly surprised when I able to by it by THE TEASPOON as the recipe I'm using calls for a 1/2 or 1/4 teaspoon of each. I spent less than $3!
