The Rioja region is unique and divided into three subregions:
- Alavesa - known for expressive fruit flavor that produces full-bodied wines with higher acidity than other subregions.
- Alta - produces lighter wines with a pronounced fruit flavor and balanced acidity.
- Oriental - a region with a Mediterranean climate that produces strong wines that lack acidity and flavor, and are therefore typically used in blends with fruit juice from other areas.
The vines grow on limestone and clay soils and benefit from the moist air provided by nearby water springs. The Tempranillo grape variety is the most prevalent, contributing to the aromatic notes of the wine, followed by Grenache, which is responsible for the flavor bouquet. Rioja wines can mature for up to 18 years but are typically aged for 5 years in American oak barrels before being sold.
