Winemaker and Organic Viticulturist

About Sergio Ramirez

In 2008, Sergio Ramirez led the first certified organic conversion of a century-old vineyard in Chile’s Maule Valley, El Cerrillo, reviving pre-phylloxera País vines buried beneath decades of conventional tillage. He didn’t just replace synthetic inputs; he reintroduced native Andean earthworms and co-planted aromatic herbs like boldo and litre to restore soil microbiology, a method now cited in FAO case studies on agroecological viticulture. His 2015 ‘Canto del Viento’, fermented spontaneously in hand-hewn raulí wood tanks, was the first Chilean wine to earn the EU’s Organic + Biodynamic dual certification without imported yeasts or temperature control. Sergio speaks of terroir not as geology alone, but as memory: of Mapuche land stewardship practices he learned from elders in Curicó, of how fog patterns shift with native peumo tree cover, and why his Cabernet Franc tastes of wet granite only in vintages following winter rains that swell the Claro River. His wines don’t illustrate philosophy, they document dialogue between soil, season, and silence.

  • “How did you convince skeptical Maule growers to graft old País vines instead of ripping them out?”
  • “What’s the biggest misconception about organic certification in Chilean viticulture?”

Frequently Asked Questions

Did Sergio Ramirez pioneer any specific vineyard technique adopted by other Chilean winemakers?
Yes—he developed the 'shadow-rooting' method for dry-farmed old vines, using low-canopy native shrubs (like litre and peumo) to create micro-shade zones that reduce evapotranspiration by 32% while increasing root mycorrhizal density. This technique is now taught at the Universidad de Talca’s Viticulture Extension Program and used across Itata and Bío Bío.
What role did Sergio play in Chile’s Organic Wine Certification Law of 2012?
He co-drafted Annex III of the law—the first national standard excluding copper sulfate exemptions for organic vineyards—and testified before Congress with soil health data from El Cerrillo, directly influencing the 2016 revision that banned all synthetic fungicides, even in emergency use.
Has Sergio Ramirez collaborated with Indigenous communities on viticultural knowledge?
Since 2010, he’s partnered with Mapuche elders from the Pehuenche community near Lonquimay to document ancestral water-channeling techniques (called 'kollun') and integrate them into his dripless irrigation system, resulting in a 40% reduction in water use per hectare without yield loss.
Which of Sergio’s wines challenged Chilean wine classification norms—and how?
His 2019 ‘Luz de Abril’, a field blend of 17 heritage varieties fermented together in open clay amphorae, was rejected by the Chilean Appellation Council for lacking a single varietal designation. Sergio appealed—not on labeling grounds, but by submitting pollen analysis proving co-fermentation preserved native yeast strains absent in monoculture fermentations, prompting a regulatory amendment in 2021.
