The French 75 was born in Paris between 1915–1925 at Harry’s New York Bar—gin, lemon, real Champagne—and named for a WWI cannon that fired 30 rounds/min. Today’s blueprint: 1 oz gin, 0.5 oz lemon + simple, hard-shake 12–15 sec, strain cold, top with 2 oz Champagne and a lemon twist; New Orleans’ Arnaud’s swaps in cognac. Dormant for decades, Dale DeGroff revived it in the ’90s; now it’s the celebratory classic (~15% ABV)—and yes, use Champagne, not Prosecco.
