high-altitude blueprint of modern Argentine viticulture crafted by the visionary Michelini brothers. Sourced from the prestigious Tupungato Winelands at a staggering 4,264 to 4,800 feet above sea level, this single-vineyard 100% Malbec reflects an extreme, desert-like alpine environment. The vines dig deep into complex, alluvial soils dominated by sand, stones, and a remarkably high concentration of calcium carbonate (chalky granitic limestone). Head winemaker Juan Pablo Michelini deliberately capitalizes on these high-toned terroirs by harvesting notably earlier than regional standards. This preserves an electric, linear core of natural acidity and completely sidesteps the jammy, overblown ripeness historically associated with Mendoza.

On the technical vinification front, the 2024 vintage showcases a highly structured, low-intervention approach. The grapes are entirely hand-harvested in small boxes and undergo a spontaneous fermentation with native yeasts inside a combination of cement and stainless steel vats. For structural extraction, Michelini utilizes an extended 42-day skin maceration, yielding profound phenolic depth and architectural density. The wine completes malolactic fermentation and is aged for 12 months in seasoned French oak barrels. For technical geeks, the calcareous footprint manifests instantly on the palate: it delivers an explosive aromatic profile of fresh plum, blueberry, and violet, pinned down by savory undertones of graphite and wild oregano. The true hallmark of this Gualtallary terroir is its distinct structural tension, driving a long, saline, and intensely chalky, fine-grained tannin finish
