The story you've probably heard

The shallow, wide-bowled coupe glass — the one under a Gimlet, an Aviation, a Daiquiri — comes with a favorite bit of bar trivia: that its shape was modeled on Marie Antoinette's breast, supposedly cast from a mold made for her. It's a great line. It also can't be true.

The math that breaks the story

The coupe shape traces to English glassware from around 1665–1670 — a wide, shallow drinking form made in a Greenwich glasshouse backed by the Duke of Buckingham, overlapping with George Ravenscroft's lead-crystal innovations of the 1670s. Marie Antoinette wasn't born until 1755. The glass predates her by roughly ninety years — not a small gap, a full human lifetime before she existed to model anything.

Where the myth probably came from

There's a real historical detail that likely got mixed up into the legend: in 1787, Louis XVI gave Marie Antoinette a set of jattes-téton — breast-shaped porcelain milk bowls — for her retreat at Versailles. Those were real, and they were shaped the way the legend describes. They were also porcelain milk bowls, made a full century after the coupe glass already existed, and they have nothing to do with champagne or cocktails. Somewhere along the way, two unrelated objects got flattened into one good story.

Why it still works for cocktails

Whatever its real origin, the shape does something specific: wide and shallow means more surface area, which means a shaken, chilled cocktail warms up faster than it would in a narrower glass — the tradeoff bartenders accept for the silhouette. It's the glass behind a long list of shaken sours: Gimlet, Aviation, Last Word, White Lady, Bee's Knees, Southside, Daiquiri, Margarita.
