Diageo announced it is launching a new 70cl aluminium bottle for its Baileys brands.

The new packaging format promises to cut carbon emissions by 44% compared to glass bottles.

The aluminium bottles are five times lighter than the traditional glass Baileys bottles.

The new packaging will initially only be available at selected airports for a trial period, starting this month.

“As the largest global spirits brand to join the B Corp movement, we are proud to drive our progress in the community with our latest innovation to deliver positive impact,” said Sarah Blake, global brand director, Baileys.

“While this is an important milestone for Baileys, we know that there is more we can do. We are already looking forward to the delivery of more initiatives as we journey towards our 2030 commitments.”

An initial 30,000 bottles will be available through a partnership with German travel retailer Gebr Heinemann GmbH.

They will be available at Amsterdam Schiphol, Frankfurt, and Copenhagen international airports. Later in May, it will be available in domestic retailer stores across Germany for a limited time only.
