The reserva wines of Marqués de Riscal are made basically from grapes coming from vines over 15 years old, of the Tempranillo variety. This is a variety that ages well in wood, producing wines with a good tannic structure, color and acidity during the ageing process. The reserva wines of Riscal spend approximately two years in American oak barrels, forming a wine which adheres to the principles of classic Rioja wines.
