Maple Whiskey Sour

Bourbon, lemon, and maple — the 1862 Whiskey Sour given maple, Canada producing 70–75% of world supply from an Indigenous technique predating European contact.

The Maple Whiskey Sour applies the Whiskey Sour's three-part sour structure to a sweetener with genuine regional character, reflecting the craft cocktail movement's sustained push to replace neutral sweeteners with more flavorful alternatives wherever the substitution strengthens rather than obscures the base spirit. The Whiskey Sour was first published by Jerry Thomas in his 1862 Bar-Tenders Guide, and the formula — spirit, lemon juice, sweetener — has remained structurally unchanged for over 160 years while accommodating an enormous range of spirit and sweetener variations. Canada produces approximately 70-75% of the world's maple syrup supply, with Quebec alone accounting for roughly 90% of Canadian output. Vermont, New York, Maine, and other northeastern American states produce the remainder of North American supply. The maple industry is North America's oldest sugar industry, predating European contact: Indigenous peoples including the Anishinaabe and Haudenosaunee peoples had developed maple sap harvesting and syrup production techniques centuries before Europeans arrived, and the knowledge was shared with colonists who incorporated it into their own food and drink traditions. In a Whiskey Sour, maple's complexity — its caramel, vanilla-adjacent wood-sugar aromatics, and the sotolon lactone that defines its distinctive character — interacts with bourbon's own barrel-derived sweetness in a mutually reinforcing way, producing a sour whose sweetness is layered and interesting rather than simply present.
