Briefings

The Regional Wine Commission of Alentejo (CRVA) announced a new lightweight wine bottle project in October 2026, targeting a 390-gram weight to reduce costs and emissions. Developed with Verallia, the initiative aims to meet the 420-gram target set by the Sustainable Wine Board, though market resistance to lighter bottles remains a challenge. Production and quality testing for the first quarter of 2027 are underway, with potential annual savings of 1.5 tons of glass and 1.2 tons of carbon emissions if 50 million bottles are sold.

Key points

• The CRVA launched the 'Garrafa Leve do Alentejo' initiative in October 2026, targeting a 390-gram weight for wine bottles.
• The project aims to reduce annual glass consumption by 1.5 tons and carbon emissions by 1.2 tons if 50 million bottles are sold.

Context

The CRVA, representing Alentejo's wine sector, developed this initiative in partnership with Verallia and local producers. It aligns with the Sustainable Wine Board's 420-gram target and supports the broader 'Programa de Sustentabilidade dos Vinhos do Alentejo' which has reduced water and energy use by up to 30% and 20% over five years.

Limitations

Testing for bottle durability in long-distance logistics begins in Q1 2027. Market resistance to lighter bottles remains a challenge, and the 50 million bottle sales target is a future projection rather than a confirmed outcome.
