Not long ago, Buenos Aires residents stuck to the basics: Beer, wine, and fernet, an Italian digestif extremely popular at parties and bars throughout the city. But the local palate is changing. A cocktail movement is in the works, with bartenders perfecting classic cocktails and crafting creative libations from fresh fruits and botanicals. Look for drinks made with vermouth, a nod to the city’s Spanish and Italian immigrant past, at Buenos Aires’ best cocktail bars, such as 878 in Villa Crespo and Doppelganger in San Telmo. If you want the real Argentine experience, and you can stomach it, do as the locals do and ask for a fernet and cola.
