Abstract

Carignan is one of those minor cultivars that have had a major resurgence in the Chilean wine industry, and its production is sold at a price well above the national average. This variety, together with other autochthonous grapevine varieties, makes up a unique heritage in Chilean winemaking, which has given a new identity to the country on the world wine scene. Chilean viticulture is based on the production of the most recognized grapevine varieties such as Cabernet Sauvignon, Merlot, Chardonnay and Sauvignon blanc. However, this has caused a massive loss of minority and autochthonous grapevine varieties in certain wine growing regions. Thus, this review summarizes the effects of terroir of the Maule Valley on the typicity of Carignan. Carignan grapevines growing in the sites closer to the Pacific Ocean, such as Truquilemu and Cienaga de Name, present a high concentration of several amino acids and volatile compounds in grapes and wines, while Carignan grapevines growing in the sites further east, towards the Andes Mountains, provide grapes and wines with a high alcohol and phenolic concentration. Therefore, Maule Valley provides unique edaphoclimatic conditions that allow differences in the composition and style of the Carignan wines.
