Synthetic cork, but one of stand-up performance, longevity e quality, with easy sliding pull. Bright blueberry initial whiff. Tastes so soft as to be nearly invisible with round shouldered mild mannered tannins. Small faint cranberry notes in medium body mouth feel, chalky mineral structure, slight herbaceous grassy edge, terminated to easy spice and 10 second clean finish. Just what thou would want in a case of wine meant not to impune anyone's tastes. Truly egalitarian reasonably priced well crafted everyday vino, yes? Solid 88 pts. (Grazie Espainoza!)
