National Mate Festival in Parana
Argentina's only National Mate Festival, held in Paraná since the mid-1980s and granted its exclusive national title in 1995 based on Entre Ríos having the country's highest per-capita mate consumption, with roots as a modest neighborhood gathering that grew into a major outdoor concert event.
Argentine regulations bar two national festivals from sharing the same theme, and that rule is why Paraná's mate festival, first held at Club Echagüe in the mid-1980s, remains the only event in the country entitled to call itself the National Mate Festival.
