Craft beer maker BrewDog intends to invest £10m in its Scottish brewery.

The Aberdeenshire firm said the expansion will help it meet demand for its beer across Europe.

It aims to raise the money from backers through its shareholder scheme, Equity for Punks.

If BrewDog is able to raise £50m, it will spend another £2m building a new warehouse in Ellon.

Co-founder James Watt said: "It is impossible to deny the significance of this early success of Equity for Punks and what it could mean for our dream to take the craft beer revolution truly global.

"Raising over £1m in just two days shows the rife passion for a new business model founded in community and driven by purpose, not profit."

To mark the launch of the latest round of Equity for Punks, BrewDog brought a 17ft "Trojan dog" to London.

Mr Watt added: "Our Trojan dog stood overlooking London's financial district as a stark reminder of the undeniable significance of crowdfunding and our invasion of the status quo.

"It marked a new dawn and quenched people's thirst for change."

BrewDog, which is worth £1bn, has thrived on its punk aesthetic since it was founded in Fraserburgh in 2007.

Its value rose significantly earlier this year after a quarter of the business was bought by US investors TSG Consumer Partners.

Watt and co-founder Martin Dickie reportedly earned up to £100m from the £213m deal.
