Region — specificity = quality
Bigger to smaller = lower to higher. A wine labeled “Argentina” is bulk-blend territory. Mendoza narrows it. Uco Valley narrows it further. Gualtallary — a sub-region of the Uco Valley — narrows it again.
The more specific, the more legal restrictions were followed, the more the producer cared.
Argentine hierarchy: Province (Mendoza, Salta, La Rioja, etc.); Region/DOC (Luján de Cuyo and San Rafael are the only two DOC regions, plus Uco Valley); Sub-region/IG (Gualtallary, Paraje Altamira, Cafayate, Vista Flores).
