Luigi Bosca

Leoncio Arizu, the first generation of the family in Argentina, arrived in Mendoza in 1890 and settled in Luján de Cuyo, where he founded Bodega Luigi Bosca in 1901. The family's heritage is in Unzué, a small town in the Spanish Basque Country, where it had made wine since the 18th century. In 1926 the family acquired Finca El Paraíso in Maipú. The second generation joined the winery in 1933, bringing professionalism and technical know-how, and in 1934 a historic flood struck Mendoza while the harvest continued on horseback. The third generation stepped in in 1963, starting a phase of genetic material selection and vineyard expansion into new zones. In 1989 Luigi Bosca became a founding member of Argentina's first D.O.C. (Denomination of Origin), in Luján de Cuyo, with Ing. Alberto Arizu a key voice on its council, and in 1991 the family launched the first Malbec under the D.O.C. Luján de Cuyo. The fourth generation entered in 1992. In 2010 the harvest produced 6.5 million bottles, split between the high-end Luigi Bosca label and the value-priced Finca Los Lindes wines. As of 2015 the winery remained in the hands of the founding family and was led by the third and fourth generations.

It presents the De Sangre Malbec Valle de Uco as 'a tense, fresh and highly concentrated wine' and Filos as a Chardonnay with 'a clear fruit profile, marked minerality, and sharp acidity.'
