A sour and fruity cocktail ∙ Dry shake ∙ 5 min ∙ 14.9% ABV ∙
The Sour Grapes is an egg-white sour blending bourbon and Pineau des Charentes with lemon juice and sugar syrup, double-shaken and served up.
The Sour Grapes is a modern whiskey sour built with an equal measure of Pineau des Charentes, the French grape-and-Cognac aperitif that gives the drink its "grape" name and its fruity backbone alongside the bourbon. It is credited to bartender Robb Jones, created in a straight-up bourbon-based version at Bellecour, a French-inspired restaurant and bar in Wayzata, Minnesota. The widely circulated recipe is an adaptation of that original, served as an egg-white sour.
45 ml bourbon, 45 ml Pineau des Charentes blanc, 25 ml fresh lemon juice, 10 ml sugar syrup and half a pasteurized egg white, with optional Angostura bitters.
Shaken, and shaken twice. It is first shaken with ice to chill and dilute, then strained back into the shaker and dry-shaken without ice to whip the egg white into a stable foam before fine-straining into the glass.
