Quality control in Rioja became even stronger in 1985, when the Rioja Regulatory Council implemented a rigorous classification system to further ensure consistent quality across all Rioja wines.

- Declaration and control of production.

- Use of guarantee seals on bottles.
Physical Control
- Traceability.
- Wine-volume assessment.
