Cans of Irn-Bru have been an unexpected talking point at the COP26 summit with many delegates trying the beverage for the first time.

US congresswoman Alexandria Ocasio-Cortez revealed she was a big fan of the drink after sampling some while in Glasgow.

In an Instagram video, she said: “Oh my God, love it, love it. This tastes just like the Latino soda Kola Champagne.”

“I was so shocked at having something in Glasgow that tasted like home,” she added in a caption. “However Irn-Bru is also very unique on its own. It’s got pizazz. Will bring some cans home to NY for sure!”

Scottish first minister Nicola Sturgeon tweeted a photo of herself handing a can to Ocasio-Cortez on Wednesday.

“Amidst all the serious business at Cop26 today, I’m pleased to also report that AOC now has a supply of Irn-Bru,” she wrote.

Ocasion-Cortez responded: “Talk about Scottish hospitality! Thank you for the (very special) delivery, Madam first minister.”

A spokesperson for Irn-Bru said: “It’s phenomenal that Scotland’s ginger nectar has made such a splash with delegates from across the globe.”

The beverage has been available throughout the SEC convention centre due to a deal between the building’s owner and drinks manufacturer AG Barr.
