BrewDog’s “CEO of beer” — former Red Bull UK MD Andy Shaw — has left the Aberdeenshire craft brewing firm just five months after joining the company, according to a report in trade publication The Grocer.

BrewDog hired Shaw in February to lead its global sales and marketing operations and the reasons for his departure are unclear, the report said.

Confirming Shaw’s departure to the trade publication, BrewDog CEO James Watt said: “We would like to thank Andy for all the hard work during his time with us and wish him all the best for the future.”

Shaw did not comment.

BrewDog has promoted David McDowall, formerly its retail CEO, to a new role as group COO, in which he would have “full P&L control over both BrewDog Retail and HQ Beer: two of the main engines of our business,” said Watt.

“I have worked very closely with David over the last five years on our global retail business, and we work really well together and are very aligned in terms of how we want to do things.”

Last month, BrewDog was named the most valuable craft beer brand in the world and the 19th most valuable global beer brand in the Brand Finance report on the most valuable and strongest beer brands.

The report said: “Innovative Scottish craft beer brand, BrewDog, is the highest new entrant in the ranking in 19th position, with a brand value of $1.5 billion.”
