Rioja wine region launches experimental program for lower alcohol red wines

The Rioja wine region in Spain has started a new phase in its winemaking approach by approving a program to experiment with red grapes that have lower alcohol potential than currently allowed. This decision was made by the Regulatory Council of the Rioja Qualified Designation of Origin (DOCa Rioja) on Tuesday, August 19. The move follows a recent change to the region’s official regulations, approved on June 13, which now allows for the production of wines with lower alcohol content.

This experimental program responds to growing market demand for wines with less or no alcohol, often referred to as “No-Lo” wines. Over the past year, this category has seen significant growth worldwide, as consumers look for lighter options that fit changing lifestyles and health trends. Rioja, known for its traditional red wines, is now positioning itself to compete in this expanding segment.

The council’s plan involves testing new winemaking techniques that could produce red wines with a minimum alcohol content of 10% by volume. Currently, Rioja’s rules require red wines to have at least 11% alcohol by volume. For specific categories such as Crianza, Reserva, Gran Reserva, and Viñedo Singular, the minimums are even higher—11.5% and 12% respectively. While the recent regulatory change allowed white grapes to be harvested at lower sugar levels (reducing the minimum from 10.5% to 9%), the standard for red grapes remained unchanged until now.

The main concern behind maintaining higher minimums for red grapes has been the risk of harvesting fruit before it reaches full phenolic maturity, which can affect wine quality. However, the newly approved program will allow controlled experimentation during the 2025 harvest season. Wineries must obtain prior authorization to participate, and any wine produced under this program cannot be sold commercially at this stage.

Depending on the results of these trials, DOCa Rioja may consider updating its official regulations in future years to allow broader production of lower-alcohol red wines. The goal is to diversify Rioja’s product range and boost sales while maintaining a strong commitment to quality standards.

This initiative marks a significant step for one of Spain’s most prestigious wine regions as it adapts to evolving consumer preferences and explores new possibilities in winemaking. The outcome of these experiments will be closely watched by producers and industry observers both in Spain and abroad.
