Viña Tondonia Reserva Blanco is a white Rioja wine, renowned for its long aging potential and complexity. It's typically made from Viura (Macabeo) grapes, blended with a small amount of Malvasía. The wine undergoes a lengthy aging process in oak barrels (6 years for the Reserva, according to R. López de Heredia's website) and further aging in bottle, resulting in a smooth, round taste with notes of dried fruits, citrus, and nuts.
