London, England
Using his experience as Head Pastry Chef in multiple Michelin starred restaurants in London, Bob Petrie has created a suite of single ingredient tinctures.
However, the holy grail of his efforts is the famed Abbotts Bitters. Bob resurrected this long-lost bitters recipe using a sample extraction that dates back at least 75 years, possibly even longer. Fair warning — if you try in a Manhattan even once, you will be forever beholden.
