Bodega Submarina Del Mediterráneo is based in Castilla y León, Spain, and produces still wines and sparkling wine. The bodega works across multiple Spanish wine regions, drawing grapes from Castilla y León, Cataluña, and Galicia to create a range spanning red, white, and sparkling categories.

The bodega's defining characteristic is its use of underwater maturation—a process in which wines are aged submerged in the Mediterranean Sea rather than in traditional cellars. This unconventional method exposes wines to constant pressure, stable cool temperatures, and unique environmental conditions that differ fundamentally from conventional aging. The approach reflects an experimental philosophy toward winemaking rather than adherence to a single regional style.

The current range draws from established Spanish appellations and grape varieties. Their Cava Brut Reserva uses Xarel Lo and Macabeo—the primary varieties of the Penedès region. A Ribera del Duero wine showcases Tempranillo, the signature grape of that prestigious appellation known for structured reds. A Rías Baixas Albariño represents Galicia's acclaimed white wine tradition. This geographic diversity suggests the bodega sources quality fruit from recognized regions while applying its distinctive underwater maturation technique across different wine styles.
