This is an old one. It was first published in The Bartender’s Guide by Jerry Thomas in 1862 but the concept of the sour was known and loved for over a century prior to that. During the 18th Century sea travel, especially from Europe to America, was an ordeal with malnutrition and scurvy taking its toll on the sailors. Thanks to Vice-Admiral Edward Vernon, The British Royal Navy started to mix lemon or lime with rum and water to stave off scurvy and so the sour was born, one of the oldest types of cocktails. From there it was only a matter of time before someone started to make a sour with American whiskey and made it what it is today.

The Whiskey Sour is traditionally made with whiskey, lemon juice, sugar and egg white, an ingredient that will smooth out the tartness of the lemon juice. Today the egg white is optional and you often find bars serving the Whiskey Sour without it.

On a side note, calling a spirit diluted with water a grog is also because of Vice-Admiral Vernon. He was known for wearing grogram coats giving him the nickname ”Old Grog”.

The glass called Dondolino was designed by Setsu & Shinobu Ito in 2016 and is painted using a technique with Japanese lacquer called Urushi, generally applied on wood.
