In late July 2026, the regulatory council of the Denominación de Origen La Mancha met in Tomelloso and proposed amendments to its charter that would give wineries greater flexibility to produce partially and fully de‑alcoholized wines. The measures, including a guarantee scheme for 0.0 % alcohol wines, were presented as a response to a global decline in wine consumption and shifting consumer preferences. A week later, the Consejo Regulador of the DOP Bierzo approved a set of modifications to its pliego de condiciones. The changes introduce a new irrigation regime, lower the probable alcohol degree for the Godello grape, add specific aging requirements, recognize synonym grape varieties, and set limits on new plantings. These adjustments aim to improve production practices and adapt to market conditions. Together, the two updates illustrate a broader trend among Spanish wine authorities to modernize DOP regulations, addressing both consumer demand for novel wine styles and agricultural considerations across different regions. ## Timeline ### 2026-08-05: DOP Bierzo updates wine regulations with new irrigation and aging rules Spain's ITACyL approved an update to DOP Bierzo wine regulations, adding new irrigation rules, lower alcohol limits for Godello, aging requirements and production caps, effective immediately. 2 sources. https://clstr.news/cluster/dop-bierzo-updates-wine-regulations-with-new-irrigation-and-aging-rules ### 2026-07-29: Denominación de Origen La Mancha advances rules for de‑alcoholized wines La Mancha’s DO council in Tomelloso proposed rule changes to support partially and fully de‑alcoholized wines, adding a certification guarantee to help wineries face falling global demand and new consumer tides 2 sources. https://clstr.news/cluster/denominacin-de-origen-la-mancha-advances-rules-for-dealcoholized-wines --- Cite as: Spanish wine DOP regulation changes.
