Valbuena 5º is the purest expression of red wine at Vega Sicilia. Its aging in oak and bottle lasts for five years, giving the wine its name and endowing it with great depth and aromatic richness. It represents the winery's most modern line, with a style distinct from Unico, the other flagship wine. "This is one of Valbuena's best recent vintages and, in some ways, reminded me of the 2010, with its elegance and precision," noted Luis Gutiérrez in his review for The Wine Advocate.
