Old Tom gin, maraschino liqueur, lemon juice, and orange bitters shaken together, the Casino is a gin sour built on a pre-Prohibition Martinez-style base. Juniper and cherry-almond sweetness open together, then fresh lemon cuts sharp through the middle before a faint bitters-spiced finish lingers.
The Casino is a gin, maraschino liqueur, lemon juice, and orange bitters cocktail long credited to Hugo Ensslin, who published a recipe for it in his 1916 book Recipes for Mixed Drinks while head bartender at New York's Hotel Wallick. Research has since traced an earlier printed version to 1909, in Jacob A. Didier's The Reminder, a pocket bartender's guide, making that the currently earliest documented appearance, though some accounts note copies of an even earlier edition of Didier's book may have circulated years before. Didier's original guide gave no background on the drink or its name, so why it was called Casino, and whether it refers to a specific gambling house or dance hall of the era, is not established. The recipe is essentially the same base as the Aviation cocktail with the crème de violette omitted and orange bitters and extra lemon juice added instead, and it was carried forward largely unchanged when Harry Craddock reprinted it in The Savoy Cocktail Book in 1930. A later variation, published by David Embury in 1948, replaced the orange bitters with orange juice.
An IBA cocktail is one listed in the International Bartenders Association's official cocktail list, a curated set of recipes recognized as world standards for bartending competitions and training. The list is organized into categories such as Unforgettables and Contemporary Classics, and the Casino appears among its recognized recipes.
Old Tom gin, maraschino liqueur, fresh lemon juice, and orange bitters, shaken and strained into a chilled glass. It is garnished with a lemon twist and a maraschino cherry.
It is gin-forward and bittersweet, leading with juniper and Old Tom's rounder sweetness, then cherry-almond notes from the maraschino before fresh lemon sharpens the finish. At roughly 27% ABV it drinks stronger and drier than a classic Martinez, with the orange bitters adding a light spiced edge rather than sweetness.
Shaken. The lemon juice needs the aeration and quick chill of a shake, which also softens the maraschino's sweetness into the mix rather than leaving it sitting on top.
An old-fashioned glass, garnished with a lemon twist and a maraschino cherry.
Luxardo is the most widely used and recommended maraschino liqueur among bartenders, prized for its dry, cherry-pit character rather than syrupy sweetness. It is the standard choice for balancing a gin sour like the Casino without overwhelming it with sugar.
