Telmont completes testing of lightest Champagne bottle in the world
Champagne Telmont and French glassmaker Verallia have successfully completed testing of the lightest Champagne bottle ever made, weighing 35g less than today’s standard sparkling wine bottles.
Telmont, the Champagne house with Hollywood actor Leonardo DiCaprio among its investors, has successfully completed testing of the lightest Champagne bottle ever made, following the announcement of the experiment last spring.
The eco-friendly bottle has a record weight of just 800 grams, making it 35 grams lighter than today’s standard Champagne bottles while retaining the glass’s resistance to gas pressure.
Champagne Telmont carried out its test phase on 3,000 bottles over the past year, and is now expanding production for a first batch of 30,000 of these 800-gram bottles.
Certified organic cuvée ‘Réserve de la Terre’, aged for a minimum of 3 years, will be the first wine housed in the lightweight bottle, and will be made available to customers as of 2026.
Telmont’s aim in developing the lightweight bottle was to drastically reduce carbon emissions in Champagne production. Glass bottles are a primary source of carbon emissions for the Champagne house, representing approximately 24% of Telmont’s total emissions.
Lighter 800-gram bottles will generate around 4% less CO2 per bottle produced. They will also require less fuel for transportation, ensuring additional energy savings.
New bottles are the latest innovation as part of the brand’s ‘In the Name of Mother Nature’ project, with an aim to become Climate Positive by 2030, and Net Positive by 2050. The initiative is supported by the brand’s investor Leonardo DiCaprio, who is a keen environmental advocate.
Telmont has undertaken numerous initiatives as part of the framework established in June 2021, with a focus on rethinking packaging. Telmont has eliminated all gift boxes and bespoke bottles, which are often heavier with a larger carbon footprint. All transparent bottles — made from 0% recycled glass — have been replaced with green Champagne bottles made with up to 87% recycled glass.
Verallia first initiated a reduction in Champagne bottle weight ten years ago, reducing it from 900 to 835 grams. The glass used must withstand a significant amount of gas pressure — twice that of a car tire — in order to safely house and age the sparkling wine, without risk of breaking.
Investor Leonardo DiCaprio said of the news: “With an ambitious goal of becoming the first climate positive Champagne house by 2030, and net positive by 2050, this step demonstrates Telmont’s commitment to reducing the carbon footprint of winemaking and changing the ways they cultivate, produce and transport their Champagne.”
