Astrales produces wines from Ribera del Duero, the renowned red wine region of Castilla y León in Spain. The winery works primarily with Tempranillo and Tinto Fino, the indigenous varieties that define the region's character—structured, age-worthy reds with dark fruit and mineral tension. Luma, their flagship Tempranillo, has drawn attention from major critics including Wine Spectator, Wine Enthusiast, and Wine Advocate. Christina Ribera del Duero and the estate's core Ribera del Duero bottling round out the portfolio, each built on the region's volcanic soils and continental climate. The wines reflect Ribera del Duero's reputation for depth and complexity, where altitude and diurnal temperature swings concentrate flavor and acidity.
