Bodegas Salentein is an Argentinian wine producer based in Mendoza's Uco Valley. It makes a wide range of wines from classic Argentinian grape varieties, headed by the Gran VU Blend, a Malbec-Cabernet Sauvignon combination aged for 24 months in French oak.

The estate is comprised of about 800 hectares (1100 acres) of vineyards in the high-altitude Uco Valley. Most of this is planted to red grape varieties like Malbec, Cabernet Sauvignon, and Pinot Noir, although around a fifth of the vineyard is planted to white grapes, including Chardonnay and Sauvignon Blanc.

Along with the Gran VU, Salentein makes several ranges of wines. The Primus and Single Vineyard ranges are at the top end and consist of several varietal wines made from the estate's key grape varieties. There is also a Malbec-dominant Bordeaux blend called Numina Gran Corte, and several sparkling wines made from a blend of Pinot Noir and Chardonnay. Bodega Salentein also makes wines under the Killka and Portillo labels.
