An obscure South Dakota law is putting a damper on local beer fests.

Under this law, breweries and distributers cannot serve their own product at beer festivals or charitable events.

Organizations like Main Street Square have to hire or find volunteers to pour and serve beer and buy machinery, such as mobile taps, to distribute the product. This route isn’t financially viable for some businesses.

“I hope this law can be revisited so that we can continue some of these fundraising events and keep them at capacity so that we're still encouraging local breweries and wineries to participate,” said Megan Whitman, executive director of Main Street Square.

“It definitely doesn't help small business at all, we know our product best,” said Jesse Scheitler, Lost Cabin Beer Co. co-founder. “For us to be able to be at the events pouring and talking to people, it’s pretty crucial to what we do.”

As of now, the sixth annual Black Hills Beerfest is tentatively canceled. Organizers are hoping that the law will change this upcoming legislative session.
