A dry and balanced whiskey cocktail ∙ Build ∙ 2 min ∙ 33.4% ABV ∙
The Old Fashioned is a stirred whiskey cocktail of bourbon, sugar, and Angostura bitters served over ice in its namesake glass. Dense and syrupy on the tongue, with a warming oak-driven finish and a bright citrus snap from the twist cutting through the sweetness.
The Old Fashioned – IBA is the International Bartenders Association's codified specification of the classic Old Fashioned, included among the "Unforgettables" on the IBA's official cocktail list, first compiled in 1961 and updated periodically since. As an official spec rather than a distinct invention, it fixes an agreed build for competition and bartending reference rather than introducing a new drink.
A widely repeated club legend ties its direct parent, the Old Fashioned, to the Pendennis Club in Louisville, Kentucky, around 1881, with bourbon distiller Colonel James E. Pepper said to have carried the recipe to New York's Waldorf-Astoria Hotel — though historians note that old-fashioned whiskey cocktails were already circulating decades earlier. The IBA specification follows this same basic structure of muddled sugar, bitters, and whiskey, differing from many pre-Prohibition and modern craft versions mainly in fixing standard proportions and garnish as a single reference recipe for bartenders worldwide.
Fully dissolving the sugar cube before adding ice is the key step most people rush — leftover grit or an unbalanced, overly boozy sip is the usual result. Stir gently and just long enough to chill and lightly dilute the bourbon; over-stirring waters it down, while under-stirring leaves it too strong and sharp.
The most common mistake is not fully muddling the sugar cube, leaving undissolved grains and uneven sweetness at the bottom of the glass. Others include skipping the chilled water dashes that help the sugar dissolve, stirring too briefly, or adding the bourbon before the sugar and bitters are properly mixed.
