Caves Cálem
Av. de Diogo Leite 344, 4400-111 Vila Nova de Gaia
Riverside port wine cellars where oak barrels age for years beneath nineteenth-century vaulted ceilings.
This guide to Caves Calem in Porto follows a young Portuguese merchant, Antonio Alves Calem, who broke from the two centuries of tradition that sent all port wine north to London and instead sent his own ships south and west to Brazil starting in 1859. It traces the unusual trade that gamble built, port sailing out, rare timber sailing back, and how a small caravel ended up painted on every bottle the firm makes. Stand in the cellars themselves, steps from the river those ships once left from, while you listen.
