High-altitude Argentine wines tend to have elevated acidity because the climate features cooler nights and a wide day-to-night temperature swing. These conditions slow ripening and help preserve the grapes’ natural acidity, so even as sugars accumulate on warm days, the acids remain relatively abundant. When the juice is transformed into wine, this preservation translates into a brighter, crisper acid profile that gives freshness and balance to the wine. Winemaking steps like malolactic fermentation can soften acidity somewhat, but the higher starting acidity from the vineyard remains a defining characteristic. So, the typical acidity level seen in these wines is elevated.
