After 3½ years of extensive research, Abbott's Bitters is just about ready to be revived. This is not a reverse engineered project, this is based on an old recipe I found that had an Abbott's name on it.
For the full history of my Abbott's research, check out this slidecast. I am taking pre-orders for bottles of Abbott's which should ship sometime in May or very early June. Pre-orders can be placed here for the Abbott's Kit (Abbott's, Acid Phosphate and Lactart plus a free ebook copy of Fix the Pumps) or you can just order a bottle of Abbott's.
