Observatorio Tagua Tagua
Observatory in San Vicente de Tagua Tagua with its own wine: its stargazing nights begin with a glass of Cabernet aged with meteorites or of Atrapacielo, a blue late harvest.
Family winery in San Vicente de Tagua Tagua, running since 1902 with 500 hectares of its own. Its Tagua Tagua and Vinos C wines are sold online, at Jumbo and in its wine shop; no tours advertised.


Viña BTT is the name under which Bodegas Tagua Tagua now presents itself, the family business of the Correa Lisoni siblings, the fifth generation of a family in wine since José Gregorio Correa Albano, one of the founders of Viña San Pedro. The house dates its origin to 1902, with its first winery in San Vicente de Tagua Tagua. The following generations added estates in Cachapoal, Colchagua and Maule, planted vines on the hills of Los Maitenes, irrigated by concrete channels, and for decades sold their output in bulk to large Chilean wineries. Direct exports began in 2005 and bottled-wine exports in 2015; according to the company, it now reaches more than 50 markets, with Brazil the largest.
The winery declares 500 hectares of its own between the Rapel Valley and the Maule: Los Maitenes (150), La Muralla (100), Pencahue (100), Almahue (50), San Fernando (50) and Cauquenes (50). Its winemaking cellar at Los Maitenes and its bottling plant at La Muralla total some 10 million liters. The Tagua Tagua brand, named after the tagua, a coot found in the area's wetlands, runs from Reserva to Gran Reserva, Family Reserve and Limited Edition, with Cabernet Sauvignon and Carménère as its backbone, plus Carignan, Pinot Noir, Chardonnay and blends. Vinos C is its most exploratory line: a Carignan from 70-year-old vines and a blend from the dry-farmed lands of Cauquenes, a Chardonnay from Mulchén and a Carménère from Colchagua. The website also announces the El Bueno brand, and the company sells bulk wine and makes private labels for importers.
The winery publishes no regular tours or tastings on its property: the Visítanos menu on its website does not yet lead anywhere. It does have a wine shop in San Vicente de Tagua Tagua, found on GPS as Viña Tagua Tagua, where in late August 2026 it held a special sale of export overstock, open Monday to Friday 8:00 to 18:00 and Saturday 8:00 to 15:00. Regular hours are not published, so call or write to +56 9 9269 2342 before going. The company's registered address and its winemaking cellar are at Fundo Los Maitenes, whose hamlet lies about 3.5 km east of the shop. The wines are bought at tienda.vinabtt.cl, in packs of 2 or 6 bottles with shipping throughout Chile (from CLP 6,590 a bottle in a pack of 6), and at Jumbo, La Cav and specialist shops. It should not be confused with the Observatorio Tagua Tagua, a separate stargazing project about 11 km to the northeast.
