MicroBio Wines is an artisanal, family-run winery located in the small municipality of Nieva, within the province of Segovia, in the autonomous community of Castile and León.
The founder is Ismael Gozalo, who represents the fifth generation of a local family of winegrowers. He launched MicroBio Wines in 1998 as an independent, parallel project to experiment and produce wines in total freedom.
The winery operates according to the principles of organic farming and bio-synergies, minimizing intervention both in the vineyard and in the cellar. Here, production relies on indigenous yeast fermentations, with no fining or filtration, and minimal to no use of sulfites. The name itself highlights the importance of natural microbiological processes—such as fungi, bacteria, and yeasts—which give life and character to the wine.
Terroir and Vineyards
Gozalo's vineyards are located at a remarkable altitude, ranging between 800 and 1,000 meters above sea level. The soil is characterized by a high presence of siliceous sand of marine origin—a true fossil ocean—which gives the wines a distinctive and pronounced savory and mineral note. Thanks to this sandy composition of the soil, which protected the roots from pests, Ismael preserves centuries-old, ungrafted pre-phylloxera vines, some of which are over 200 years old.
The estate owns approximately 31 to 35 hectares of vineyards, producing around 35,000 bottles per year. The main white grape is Verdejo, the undisputed king variety of the area, which Ismael crafts into many unique versions. These range from vinification in stainless steel and terracotta amphorae or tinajas to aging in wooden barrels, as well as skin-contact orange wines and ancestral-method sparkling Pet'Nats. The estate also grows various red grape varieties, including Tempranillo, Syrah, Merlot, and Rufete.
