In 1851, at the age of twenty-two, Augusto de Muller y Ruinart de Brimont (1829-1893) arrived in Tarragona from Reims. Belonging to a prominent winemaking family from Alsace, De Muller sought an area in Spain untouched by the phylloxera plague, where he focused his activities on the production and export of wines. The volume of his international sales, with branches in Bordeaux and London, made him the leading businessman in Tarragona during his time, a city where, for much of the first third of the 20th century, the wine trade was the main economic driver, overshadowed by other, far less significant, activities. The port of Tarragona became De Muller's export hub.
