Tempranillo is a red wine grape variety primarily grown in Spain, although it has gained popularity in other wine-producing regions such as Portugal, Argentina, and the United States. Known for its versatility and ability to express terroir, Tempranillo wines often exhibit flavors of red fruit, plum, cherry, and spice, with varying levels of tannins and acidity depending on factors like region and winemaking style. It is the principal grape used in several renowned Spanish wine regions, including Rioja and Ribera del Duero, where it produces complex and age-worthy wines. Tempranillo is celebrated for its ability to be enjoyed young, with vibrant fruit flavors, or aged, developing more nuanced characteristics like leather, tobacco, and earthiness over time.
