Five years ago, Minnesota’s craft beer industry had hit a wall.

But the Surly bill, signed into law in May 2011, changed that by allowing breweries to serve their own beer onsite, creating taprooms that spawned dozens of new ones. The phenomenon also impacted Minnesota’s commercial real estate landscape, a new report by CBRE Research found.

Before the bill, there were only two breweries with taprooms in the Twin Cities. Today, the region boasts 45 breweries with taprooms, filling nearly 500,000 square feet of real estate.

“With this data, we can better understand this growing industry that involves nearly every commercial real estate product type,” said senior associate Sandy Barin, who specializes in industrial properties at CBRE, in a release about the report, called “Craft Brewing’s Impact in Minnesota.”

The wave of craft breweries primarily affected retail and industrial sites, but it also created new construction and office space. According to the Brewer’s Association, the industry has had a $1.3 billion impact on Minnesota’s economy, the 14th-biggest effect among all states, the report found.

CBRE expects at least another 70,000 square feet will be filled in 2016 by 14 microbreweries and taprooms.
