The co-founder of Brewdog has made a bid to buy back the beer brand after it was sold to a US cannabis firm earlier this year.

James Watt, who stepped down as chief executive of Brewdog in 2024, said he had formally submitted an offer to buy the brand back from Tilray.

Brewdog, which was once estimated to be worth £2billion, was sold to the Nasdaq-listed firm for just £33million in March after putting itself up for sale.

The deal included Brewdog's intellectual property, UK assets and some of its US sites, including its Las Vegas bar, as it seeks to branch out into energy drinks.

Watt had reportedly pursued an offer for parts of the beer brand, alongside the private equity firm Modella Capital, but lost out to Tilray.
