The Vancouver Sun reports that the craft beer industry has become so big that you can now study it at some schools.

Universities tap into growth in craft beer industry by offering business classes

With an explosion in growth in the craft beer industry over the last decade, it’s not enough to simply have a passion for brewing and beer when it comes to starting a brewery or working for one as the industry gets more competitive.

Recognizing that, some universities are now offering programs on the business of craft beer.

In the last decade, the number of craft breweries has grown to more than 4,000 in the U.S. today, from more than 1,400 in 2005, according to the Brewers Association.

A lot of breweries started out five or 10 years ago with a focus on beer, said Gregory Dunkling, director of the University of Vermont’s new online business of craft beer certificate program, which starts in February. Back then, a home brewer may have been able to create some great recipes but didn’t have the business acumen so along the way hired staff to cover marketing, sales, the business operation, he said. It’s harder to pull that off today.

As the industry has grown and become more competitive, the bar has been raised for those starting a brewery or working for one, said Bart Watson, chief economist with the Brewers Association.

“Certainly the demand for people with a high level of brewing knowledge has gone up and on the business side as well. So I think we’re seeing a variety of different programs look for ways that they can capitalize on that,” he said.

Portland State University in Oregon started an online business of craft brewing program in 2013, with the first cohort filling up in the first week with around 40 people. It’s become one of the school’s most successful professional certificate programs, drawing people from around the world, said Scott Gallagher, the university’s director of communications.
