Viura is a synonym for Macabeo and is the most widely planted white grape variety in Rioja. It is a fairly straightforward grape to cultivate, although it is susceptible to disease and in particular to downy mildew and grey rot. It is a generous-yielding grape and in Rioja it tends to be blended with approximately 5% Malvasia to produce classic white Riojas. In Rioja Alvesa it is often blended with Tempranillo to produce high quality Red Riojas.
In the wrong hands, Viura can produce rather neutral tasting wines. However skilled winemakers manage to preserve the grape`s natural aromatic freshness and produce wines that are enhanced by oak maturation rather than overwhelmed. Marqués de Cáceres and Herencia Remondo are widely recognised as two of the finest exponents of Viura in Rioja.
