Cune (an acronym for Compañía Vinícola del Norte de España) was founded by brothers Eusebio and Raimundo Real de Asúa in 1879. Now one of Rioja's most important wineries, Cune was among the 19th century producers that helped define classic Rioja, growing several grape varieties (predominantly Tempranillo), fermenting and blending the wines in large wooden or concrete vats, and then maturing them in barrel for many years before release.
Cune was one of the first bodegas to bottle and export its wines, and one of its earliest labels, which gained renown in the 1920s, was called Imperial. It was intended for the English market, and bottled as an "Imperial pint," about 500ml. (There are actually two Imperial bottlings-Reserva and Gran Reserva. In general, Gran Reserva is made with fruit from older vines and spends extra time in barrel.)
