Chilean wine producer Viña Concha y Toro is set to reduce the average weight of its 750ml still wine bottles to 420g or below by the end of 2026.
The commitment follows on from the company signing up to the global platform Sustainable Wine Roundtable's (SWR) Bottle Weight Accord.
Set up in November 2023, the agreement aims to lower the carbon footprint associated with wine packaging.
Viña Concha y Toro, with a portfolio that includes brands such as Casillero del Diablo, Trivento and Bonterra, produces approximately 384 million bottles of wine annually.
It has more than 12,000ha of vineyards spread across Chile and Argentina in South America and California in the US.
Viña Concha y Toro sustainability director Valentina Lira said: “As part of our overall Sustainability Strategy, VCT is already involved in many key initiatives to reduce our carbon footprint, and the fact that key retailers from around the world are also signatories to the Bottle Weight Accord gives it extra impact and influence."
Lira said the company is “well on the way to the 420g average thanks to great efforts made by our product design, packaging, production, and sustainability teams to date".
She added: “This is just the first step for us as we look to continue reducing the weight of our bottles and incorporate new formats in the future."
According to the Casillero del Diablo producer's "impact report" for 2023, that year it reduced the carbon dioxide emissions in its packaging by 22,319 tons compared to a 2020 baseline.
For the first nine months of 2024, Viña Concha y Toro reported a 16.9% year-on-year increase in revenues, reaching 675.71bn pesos ($686.52m).
From January to September, strong performances in the UK, Japan, Brazil and Mexico boosted revenue. Inflation in Argentina, a slowdown in the US, ongoing issues in China, and a sluggish recovery in Chile's beer segment partially offset the gains, the company said.
Its brands such as Casillero del Diablo and Diablo, as well as Trivento from its Argentinean subsidiary contributed significantly to the boost in sales in the period.
The profit attributable to controlling shareholders reached 52.34bn pesos, marking a 99.7% increase compared to the same period last year.
In the third quarter, the company registered a 9% rise in sales, to 232.2bn pesos.
