B&B By Benedictine is one of the oldest premixed cocktails. In the 1930s, during Prohibition in the United States, a barman at Club 21 in Manhattan came up with the idea of mixing brandy with Bndictine.

In 1937, Le Palais Bndictine decided to produce this by blending 60% Bndictine with 40% fine French Brandy, allowing the flavours to rest and harmonise in small, vintage French oak barrels that have previously been used to age only the finest cognacs.
