The Eguren brothers made this Rioja Sierra Cantabria Sauvignon Blanc 2020, a Spanish white wine from Rioja. It is accompanied by a higher amount of white Tempranillo in this vintage. Viura, Malvasa, and Maturana are also used in the blend. The Sauvignon has also undergone partial fermentation in French oak barrels, resulting in a crisp, expressive white that wonderfully embodies the RiojanSonsierra.
