Natural Wine Minimal Intervention Nomad Project Terra Alta Penedès

Celler els Mecanismes is the personal project of Òscar Soneira, a Barcelona-born communicator, sommelier and educator. It is a nomadic winery —with no physical premises of its own— that makes wines from grapes of selected estates in Terra Alta and the Penedès, always in collaboration with trusted artisans. The philosophy is clear: native yeasts, spontaneous fermentation, no fining or filtration, minimal or no sulphites, and ageing in unconventional vessels such as chestnut vats or stainless-steel tanks.

Terra Alta: calcareous and sandy soils near Villalba dels Arcs, Cariñena vineyards in collaboration with Óscar Navas (La Furtiva). Penedès: clay-limestone soils of Pacs del Penedès, Macabeo vineyards with the centenary Bodega La Xarmada. The diversity of places feeds the diversity of wines: from the lively red of Terra Alta to the mineral white of the Penedès.

Celler els Mecanismes fits fully into the Catalan natural wine scene. The two regions where it operates, Terra Alta and the Penedès, bring very different characters: Terra Alta is an inland territory with calcareous soils and wines of body and depth; the Penedès is the territory of Macabeo and cava, which here is expressed in a natural, mineral key. Òscar Soneira builds the project on years of wine communication and outreach —podcast Vino y Mantel, collaborations in Hule y Mantel y El País— with a coherence between the values he defends and the wines he makes.
