Stratum Wines is a project by Bodega Cerrón in Jumilla, led by the fourth generation of the Cerdán family – siblings Carlos, Juanjo, and Lucía. The family cultivates about 30 hectares of high-altitude, ungrafted vines, mostly Monastrell, on calcareous soils and practices biodynamic farming. Their cultivation method has been organically certified since 1989 and was biodynamically certified by Demeter in 2021.

They focus on extensive cover cropping in the vineyards, work intensively with animals, and promote biodiversity. In the winery, they follow a minimal intervention approach, use spontaneous fermentations with native yeasts, and largely avoid the use of oak. Sulfur is used sparingly and only at bottling. This careful work results in balanced wines that show lively minerality and a pronounced sense of origin, highlighting the pure fruit.
