When the doors to the Martini Expo swung open at noon, crowds flooded into the space, beelining toward the bar where they were offered a classic gin mini-tini, a wee pink Gibson, or a half-sized lychee martini. The Martini Expo was created by drinks writer Robert Simonson and Mary Kate Murray, cofounders of The Mix, a cocktail and spirits newsletter. In the bright Brooklyn sunshine, cocktail enthusiasts and industry vets were happy to nerd out about vermouth ratios, cocktail luminaries, and various spirit applications, among other things. Guests elated for their second martini at the Fords x Confidant “Three Martini Lunch Express” event. Attendees also enjoyed a Martini Mixer Cocktail Party, where a jazz trio suavely thumped away as bartenders at 30 vendor booths shook up every kind of martini you can imagine.
