Celebrated on 08/25/2026
The Whiskey Sour is one of the oldest documented cocktails, first appearing in print in 1862 in Jerry Thomas's 'The Bartender's Guide.' National Whiskey Sour Day is celebrated annually on August 25th, a perfect time to enjoy this classic refreshment.
The Whiskey Sour has roots dating back to the 19th century, but National Whiskey Sour Day was established much later. The exact origin is unclear, but it is believed to have been created by cocktail enthusiasts or a spirits brand to celebrate the timeless drink. The date August 25th was chosen to coincide with the peak of summer, when a refreshing sour cocktail is most welcome.
Over time, the Whiskey Sour has evolved from its original recipe of whiskey, lemon juice, sugar, and water to include variations like the addition of egg white for a silky texture (Boston Sour) or a splash of red wine (New York Sour). Today, National Whiskey Sour Day is celebrated by bartenders and home mixologists alike, with many bars offering specials or hosting cocktail-making events. Social media buzzes with photos and recipes, and enthusiasts often experiment with different whiskey styles, such as bourbon or rye.
