From the label:Founded by John G. Boker in 1828, Boker’s gained popularity in New York and around the World as the finest bitters of the Golden Age of mixed drinks. Boker’s Bitters were famously the preferred brand of Professor Jerry Thomas and featured throughout his book, ‘How to Mix Drinks or The Bon Vivant’s Companion,’ now recognized as the World’s first bartenders guide.Despite being unequalled when used in the refined drinks of the bar, the devastating effect of The Volstead Act, commonly referred to as Prohibition, closed the Boker’s company in the 1920’s. Referencing recipes dating back to 1853, these recreated bitters are compounded using the finest natural botanicals and are once again being used globally by bartenders in classics including the Japanese Cocktail, Martinez, Crusta and Improved Cocktail and original libations such as the B.F.G., one of Adam Elmegirab’s winning drinks created for the Drambuie UK Cocktail Competition 2010;40 ml Drambuie25 ml Noilly Prat Rouge10 ml Laphroaig 10 year old2 dashes Dr. Adam Elmegirab’s Boker’s BittersStir until ice cold and strain into a chilled cocktail glass.
