What are the aging potential and styles of Tempranillo wines?

Different styles of the Tempranillo wines include joven (which is a young and fruity wine crianza, reserva, and gran reserva, which denote the amount of aging in oak barrels and then bottles. Joven wines are to be drunk young, while reserva and gran reserva wines age for long periods and consequently, are very complex and have a high age potential. Tempranillo wines of good quality can age elegantly for many decades, changing in flavor and texture and thus acquiring subtle notes of dried fruit, spice, and leather.
