Roldós, the market bar credited with inventing it, still pours it well over a century later and also bottles its own medio y medio for sale.
Medio y medio is an equal blend of still white wine and sparkling wine, said to have originated at Roldós, a bar in Montevideo's Mercado del Puerto operating since 1886. It's typically drunk as an aperitif before a parrillada (grilled meat) meal, poured cold at the market's bars and grill counters.
