Concreto is a declaration of intent: "This wine encourages me to accelerate the process we're already committed to," said Sebastián Zuccardi. Unaged, this Malbec from Paraje Altamira was fermented in whole bunches and has become appreciably more precise in recent years. Intense purple in color. The nose offers raspberry, blackberry, fresh plum and black olive with hints of violet. The tightly packed, restrained, chalky palate offers firm tannic bones and energy. Bloody and elemental; the concentration is somehow maintained even though the wine feels light and flavorful on the tongue.
