Apaltagua produces wines from Chile's Curicó Valley, a region in the Central Valley known for its moderate climate and ability to ripen both Bordeaux and indigenous varietals. The winery's portfolio centers on Cabernet Sauvignon and Carménère—the latter a signature Chilean grape that thrives in the valley's conditions. The Signature Cabernet Sauvignon and Envero Carmenère represent the core of the range, with a Gran Reserva Cabernet Sauvignon offering a more structured expression. These wines have been assessed by Wine Spectator, Wine Enthusiast, Wine Advocate, Decanter, and Falstaff. The Curicó Valley's continental influence and well-drained soils create conditions suited to producing wines with ripe fruit character and aging potential, qualities evident in Apaltagua's offerings.
