OC Wines

The winery

OC Wines is a family project that has been making sparkling wines since 2012. It started with a narrow idea: to make only traditional-method sparkling wine, in small volumes and by hand, from harvest to labeling. Today it produces about 7,000 bottles a year and the family handles everything, from picking and winemaking to sales. The company behind the brand is Viñedos Pastene y Concha, and at its first presentation the wines were the responsibility of winemaker Ornella Pastene. The grapes for its sparkling wines come from the Casablanca Valley; the first Inicio was made with Chardonnay from Fundo La Rotunda, a gently sloping granite hillside.

Production follows the champenoise method. The must ferments in stainless steel, the base wine rests between nine months and a year in French oak barrels and steel, and each blend incorporates reserve wines from five or six earlier seasons to sustain the house style. After the second fermentation in bottle, the sparkling wines spend one to five years on their lees before disgorgement. The Inicio line comprises a Chardonnay Extra Brut and two Pinot Noir Extra Bruts, a Rosé and a Blanc de Noir; Inquieto is the Brut of Chardonnay and Pinot Noir, joined in October 2026 by the sweeter Inquieto Sec. Ciclo 1, a Brut Nature combining the 2013, 2016 and 2018 harvests and spending 43 months on lees, took first place among sparkling wines in La Cav's Guía Mesa de Cata 2025 and was chosen Sparkling Wine of the Year in Tim Atkin's 2026 Chile report; in 2024 he had already singled out the Inicio Rosé as the best-value sparkling wine. The house also makes two still wines: Fortuita Fortuna, a white of Chardonnay and Viognier from Casablanca, and El Patinto Feo, a 2023 Carménère from the Maipo Valley.

OC Wines publishes no visits, has no cellar door open to the public, and does not disclose the address of its winery; in its photos of the 2026 harvest the grapes arrive in bins from Odfjell Vineyards, whose cellar is in Padre Hurtado, in the Maipo Valley, which is why this profile places it in that municipality. Order the wines directly from the family by WhatsApp (+56 9 9332 7670), by email (inicioespumante@gmail.com) or by Instagram message, with shipping throughout Chile; the Inicio Rosé is also sold in the Club de Amantes del Vino shop. The producer is a member of MOVI, the Movimiento de Viñateros Independientes (independent winegrowers' movement), and usually brings its sparkling wines to fairs such as Movi Night, a good chance to taste them and chat with the people who make them.
