The brand also has a 1998 vintage that has been aged for 10 years - but it has sold out in the US and Germany after getting a 90-point rating in the Wine Advocate .
Guy Anderson said: "We know there is a huge and fiercely loyal market for these mature, oak-aged wines. But
there is some confusion
regarding the precise meaning of 'reserva' or 'crianza' because the ageing rules vary between Spanish DOs. Anciano makes it simple for the consumer to understand what they are buying."
Anciano 2003, aged for five years, is in Tesco priced £5.99.
