British Airways and Scottish craft brewery, BrewDog, have teamed up to create a transatlantic IPA to celebrate the airline’s centenary, and in a world first brewed beer at 40,000ft.

With the help of British Airways cabin crew, BrewDog founders Martin Dickie and James Watt, started the brewing process on board one of the airline’s Boeing 787 Dreamliners, while cruising 500mph over the north of Scotland.

The expert brewers mixed water, hops and barley in the onboard beverage makers to start the mashing part of the brewing process.

Cans of the bespoke IPA, named Speedbird 100 after the airline’s call sign, will be exclusively available to British Airways customers on board all long-haul and short-haul flights and in selected lounges from May 1st.

The recipe has been specifically brewed to work perfectly in the air and adapt to the reduction in taste and smell sensitivity at high altitudes.

Hamish McVey, British Airways head of brand and marketing, said: “We are hugely excited to have partnered with BrewDog, another British brand that is committed to bringing the best of Britain to the world.”
