Tupungato IG

Tupungato is the largest of the valley's three departments, with 10,810 hectares of vines in 2025. It also has the most wineries: 46 were registered in 2021, and 43 of them made wine. The INV had 46% of the vines in Malbec that year and 83% in red varieties overall.

The name you'll see most on a Tupungato label is Gualtallary, and it isn't a registered IG. The INV lists it as a "mención precaria", a provisional permission to use the name. One Argentine report says the name was registered as a private trademark, which blocks a future IG under it. So I read Gualtallary as a district name on the label, with no legal appellation behind it. It is high, with vineyards from 1,080 to 1,600 metres and about 2,250 hectares planted. Zuccardi describes soils that are stony and rich in calcium carbonate, with caliche in places, shaped by the Las Tunas River and the Jaboncillo and El Peral hills. Catena Zapata, Zorzal, Rutini, Andeluna, Doña Paula and Domaine Bousquet are among the wineries with Gualtallary fruit.

El Peral is the one registered IG inside the department, and it has its own page here. When I open a Tupungato bottle I'm looking for the mountain freshness, and I'll check the label for Gualtallary or El Peral before I judge it against the rest of the valley.
