Finca Torremilanos's natural wine range, debuted at the 2026 Salon Gourmets and produced alongside the Demeter-certified biodynamic portfolio, is made with minimal or no added sulfites, consistent with its natural wine certification status. The estate's Demeter biodynamic certification restricts synthetic inputs throughout viticulture; the natural wine extension applies this logic to the cellar. The specific sulfite addition levels for the natural range are documented in the producer's Gourmets catalogue entry and the estate website.
Founded in 1903, Finca Torremilanos is Ribera del Duero's most prominent Demeter-certified biodynamic estate. The 200-hectare property has held full Demeter certification for biodynamic agriculture since 2014, making it one of the first and largest certified biodynamic vineyards in Castile. The estate produces Tinto Fino-based reds across its Cyclo and Montecastrillo ranges, and in 2026 debuted its first certified natural wines at the Salon Gourmets. Biodynamic practice here encompasses homeopathic preparations, lunar planting calendars, livestock integration, and herb-based compost.
Founded in 2010 by Jorge Monzon and Isabel Rodero, Dominio del Aguila farms 66 hectares of old-vine Tinto Fino under certified organic status, verified by the Consejo Ecologico de Castilla y Leon (the regional organic certification authority). Winemaking is low-intervention: natural yeast fermentations, whole-cluster co-fermentations, foot treading, and ageing in restored 15th-century cellars. The Picaro del Aguila and Reserva are the estate's signature bottlings. Organic certification confirmed on the producer's own site and importers' pages.
