Viña von Siebenthal

The winery

Viña von Siebenthal is the project of Mauro von Siebenthal, a Swiss lawyer who left his profession at forty to make wine in Chile. In 1998 he founded the winery in Panquehue, in the Aconcagua Valley, about 120 km north of Santiago, and that same year planted his first 10 hectares. In 2000 he built the cellar, a red-walled building modeled on a country manor house, and in 2002 brought in his first harvest; in March 2026 he celebrated vintage number 25. His vineyards border those of Errázuriz, in the area where Maximiano Errázuriz began planting vines in 1857.

Today the estate has 30 hectares in production, half on alluvial soils of clay and silt and half on colluvial soils of granite and clay, at the foot of Cerro Orocoipo and about 450 m above sea level. Carménère, Cabernet Sauvignon, Cabernet Franc and Petit Verdot dominate, with smaller plots of Merlot, Syrah and Viognier; almost everything was planted between 1998 and 2000, the Viognier in 2010. Harvest is by hand, between March and May; the vineyard is farmed without pesticides or synthetic chemicals (only sulfur), fertilized with alpaca manure, and a solar plant of its own powers the winery. The house produces about 160,000 bottles a year and exports 45% to more than 20 markets. Its icon wine is Tatay de Cristóbal, a Carménère with 10% Petit Verdot aged 30 months in new barrels; alongside it come Toknar, a pure Petit Verdot, the Montelig blend (Cabernet Sauvignon, Carménère and Petit Verdot), Parcela #7, the Carabantes Syrah, the San Valentino and Orocoipo Carménères, and Riomistico, a Viognier.

Visits run Monday to Saturday between 9:30 and 15:30, always with a booking; for Sundays, ask ahead. The three tours go through the cellar and the barrel room and end with a tasting served with cheeses and cold cuts from the valley: Tierra, with three wines and from two people; Río, with four wines, including the Riomistico Viognier, and Fuego, with the house's three top wines, both from four people. According to the winery, every visit is hosted by a member of the von Siebenthal family. Book by phone at +56 9 9459 6173. There is no restaurant or accommodation; the estate has a cellar door but no online shop.
