Imperial is one of the best known brands in Spain. A true Rioja classic,  it was first produced in the 1920s with the aim of producing only top quality Reserva and Gran Reserva wines. Its name came after a special bottling for the English market, in a measure called 'Pinta Imperial' or 'Imperial Pint' (an Imperial pint is approximately half a litre). These wines are only produced in exceptional vintages.
