What are the four main red grape varieties used in Navarra DO?

The four main red grape varieties used in Navarra DO are indeed Tempranillo, Garnacha, Merlot, and Cabernet Sauvignon. Navarra, located in northern Spain, has a diverse climate that allows for the cultivation of various grape varieties. Tempranillo is the region's flagship red grape, known for producing wines with good acidity and ripe fruit flavors. Garnacha (Grenache) is also prominent in this area, contributing to the red blends with its berry fruit profile and softer tannins. The inclusion of Merlot and Cabernet Sauvignon reflects Navarra's ability to produce international varieties, which align well with its climate and terroir, allowing the region to create a wide range of well-structured and flavorful red wines.

Other options may include grapes that are less representative of Navarro’s primary production focus. While Malbec, Grenache, and Syrah are notable in other regions or wine styles, they do not stand out as the primary varieties of Navarro. Likewise, choices that involve Sangiovese and Zinfandel do not correspond to the characteristics of Navarra DO, which is more recognized for its Spanish indigenous varieties alongside international ones like Merlot and Cabernet Sauvignon.
