A fruity and sweet fortified wine cocktail ∙ Shake ∙ 3 min ∙ 15.3% ABV ∙
The Porto Flip – IBA is a flip of tawny port, brandy and egg yolk, shaken, strained into a cocktail glass and dusted with grated nutmeg.
Porto Flip is the name the International Bartenders Association uses on its official cocktail list for the classic Port Flip, listing it among the "Unforgettables" with a fixed specification of brandy, tawny port, and egg yolk. Like the Alexander and Rusty Nail, other after-dinner classics on the same list, it was an existing recipe that the listing standardized rather than a new creation.
The drink traces to Jerry Thomas's 1887 Bar-Tender's Guide, which prints a brandy-and-port flip under the name Coffee Cocktail. The IBA's Porto Flip keeps that brandy-and-port build, differing from most early published versions mainly in using only the egg yolk rather than a whole egg.
