The bitters crisis we heard about last week that threatened to wreak havoc and chaos throughout the cocktail world is doing just that. Anecdotal evidence—the best kind—suggests that NYC bartenders are hoarding bottles of Angostura bitters, one of the key ingredients to make a Manhattan, after a production shortfall hit late last year. One skeptical cocktail enthusiast and blogger went on a haphazard journey between Brooklyn and Manhattan grocery stores futilely searching for a bottle of the stuff. And wholesome barkeep Tracy Westmoreland, owner of the defunct Siberia Bar and The Manhattans in Brooklyn, told the Post how serious this shortage is: "I believe it is the end of civilization as we know it if we can't have bitters. It's like when the saber-tooth tiger went extinct. It's a terrible thing...There is no replacement. Trying to replace bitters is like trying to replace mother's milk."
