Sant Sadurní d'Anoia, October 6, 2025
A collective project growing with the land
With the addition of Mas Bertran and AT Roca, CORPINNAT now brings together 19 member wineries, reinforcing its commitment to an open and inclusive model. The brand’s regulations—considered among the most demanding in the world—ensure sparkling wines of exceptional quality: 100% organic grapes, hand harvesting, full vinification on the estate, and long ageing periods.
Since its creation on April 10th, 2018, CORPINNAT has welcomed 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 now, Mas Bertran and AT Roca.
Mas Bertran: passion and respect for the land
Located in the heart of Penedès, Mas Bertran stays true to its philosophy of respecting the land, preserving native varieties, and crafting wines and sparkling wines with genuine character. Founded in 2005 by cousins Eva Ventura and Roser Carbó, the winery has evolved from a small garage to its current facilities in Sant Martí Sarroca, growing organically and remaining faithful to artisanal craftsmanship.
Its vineyards, aged between 20 and 70 years, are cultivated with respectful, low-intervention practices that place landscape and nature at the center of production.
Mas Bertran produces all its sparkling wines from 100% hand-harvested, organically certified grapes, with a minimum ageing of 24 months, focusing on limited, high-quality production that brings the authentic taste of its land to both local and international markets.
AT Roca: identity and deep roots in the territory
Founded in 2013 by Agustí Torelló Sibill and his family, AT Roca is based in the historic lands of the Monastery of Sant Sebastià dels Gorgs, a site that embodies the bond between heritage and viticulture. From the outset, the family has embraced organic, dry-farmed, and regenerative viticulture, hand harvesting, and minimal-intervention winemaking, crafting long-aged, 100% Brut Nature sparkling wines.
The project is built on two key pillars: the vineyard and traditional grape varieties.
AT Roca represents the dedication of two generations to expressing the essence of their environment and the uniqueness of their land, offering sparkling wines that reflect the biodiversity, sustainability, and authenticity of Penedès.
One step further for CORPINNAT
With Mas Bertran and AT Roca, CORPINNAT reinforces its open and inclusive vision, strengthening a sector that not only works for itself but also protects the landscape, supports local growers, and celebrates the identity of Penedès sparkling wines. The collective brand continues to grow as a benchmark of quality, sustainability, and authenticity in the heart of Catalonia’s wine country.
