Why did Cuppaidge choose to raise money via crowdfunding - when large numbers of small-time investors help finance a project, typically via the Internet - rather than by more traditional means?
"I guess the main thing for us with the 'crowd' was that it was a crowd… to become a well-known, well appreciated brewery we needed people to know about us," he told CNBC in a phone interview.
The initial target for the Camden Town Brewery was to raise £1.5 million ($2.4 million) through crowdfunding platform CrowdCube.com. The campaign proved so popular, however, that the amount raised exceeded that figure.
In addition to the crowdfunding campaign, which ended in April this year, an outside investor also invested £10 million, meaning that just over £13 million was raised, Cuppaidge said.

Cuppaidge explained that the interaction with those who donated money was another key factor behind opting for crowdfunding.
"We engaged with them because they asked interesting questions rather than financial questions, they were interested in where we wanted to go… also, we've got now 3,000 ambassadors who ultimately want us to succeed because in our success they'll reap the benefits," he said.
Those who invested in the project were not only offered equity in the brewery, but also beer-related rewards. A £100 donation would result in a five percent discount on Camden Town beers at the brewery's bars and an invite to the Camden Town Brewery Annual General Meeting. At the other end of the scale, a £250,000 investment came with the benefit of a three-day tour of German breweries, among other incentives.
