CORPINNAT welcomes Mas Bertran and AT Roca and reaches 19 wineries
Sant Sadurní d'Anoia, 6 October 2025
A collective project that grows with the territory
With the addition of the Mas Bertran and AT Roca wineries, CORPINNAT reaches 19 members, consolidating its commitment to an open and inclusive model. The brand’s regulations, considered among the most demanding in the world, guarantee sparkling wines of great quality: 100% organic grapes, hand harvesting, full vinification on the estate and long ageing.
Since its creation on 10 April 2018, CORPINNAT has brought in the following wineries: Gramona, Llopart, Nadal, Recaredo, Sabaté i Coca, Torelló, Huguet de Can Feixes, Júlia Bernet, Mas Candí, Can Descregut, Pardas, Bufadors, Cisteller, Viader, Mas de la Basserola, Celler Kripta, DEMOST and, as of today, Mas Bertran and AT Roca.
Located in the heart of the Penedès, Mas Bertran maintains its philosophy of respecting the land, preserving native varieties and making wines and sparkling wines with their own personality. Founded in 2005 by cousins Eva Ventura and Roser Carbó, the winery has gone from a small garage to its current facilities in Sant Martí Sarroca, growing organically and remaining true to artisanal work.
The vineyards, between 20 and 70 years old, are farmed with respectful, minimal-intervention practices, placing the landscape and nature at the centre of production. Mas Bertran makes all its sparkling wines with 100% hand harvesting, organic certification and a minimum ageing of 24 months, committing to limited, quality production that reaches local and international markets with the authentic taste of its land.

Founded in 2013 by Agustí Torelló Sibill and his family, AT Roca has its estate on the former domains of the Monacat de Sant Sebastià dels Gorgs, a historic site that symbolises the connection between heritage and viticulture. From the outset, the family has committed to organic and regenerative dry-farmed viticulture, hand harvesting and minimal-intervention winemaking, producing long-aged, 100% Brut Nature sparkling wines.
The project is built on two essential pillars: the vineyard and traditional varieties. AT Roca embodies the will of two generations to convey the essence of their surroundings and the uniqueness of the place, with sparkling wines that reflect biodiversity and sustainability, offering wines with their own personality that are true to their origin.

With Mas Bertran and AT Roca, CORPINNAT reaffirms its open and inclusive approach, giving structure to a sector that not only fights for itself but also defends the landscape, supports farmers and showcases the identity of Penedès sparkling wines. The collective brand continues to grow as a benchmark for quality, sustainability and authenticity in the heart of the Catalan wine region.
