This is the flagship go the estate. In the good vintages, the Unico represents one third of its total production.
The prestigious cuvée has always been made the same way; the ageing process has never changed: the wien cannot be sold before it is 10 years old.
The grapes of Unico come from older vines (average: 35 years) and the cuvée is only made in the best vintages.
After fermentation, the wine stays for some time in large wooden vats. This is where and when its future is determined: Unico or Valbuena.
The superior qualities (Unico) will be aged for 12 months in new French oak barrels, then in American oak barrels for a duration which varies according to the vintage. Then the wine is put back into the larger vats. Unico is bottled after 6 years of ageing, on average. Then it is left to ripen in the bottle for at least 4 years.
In the greater vintages, Unico can stay longer in the oak - up to 9 years.
