Geography and climate define Argentine wine zones, and the valleys of Neuquén and Río Negro sit in the southern Patagonia region that’s influenced by the Atlantic, which together form the Patagonia & Atlantic Wine Zone. That label specifically captures both the Patagonia landscape and the maritime influence on the eastern edge, where these valleys are located, giving a cooler, longer-growing-season style of wines.

This is why it’s the best answer: those valleys aren’t in the Central Valley, Cuyo, or Northwest—those regions are in different parts of the country with distinct climates and grape profiles. The Central Valley centers around Mendoza’s inland area, Cuyo includes Mendoza, San Juan, and La Rioja, and Northwest covers northern provinces like Salta and Tucumán. Neuquén and Río Negro are located much farther south, in Patagonia, aligning with the Patagonia & Atlantic Wine Zone.
