BISMARCK, N.D. (AP) — The Bismarck area is becoming a hot spot for North Dakota microbreweries.

Bismarck, Mandan and the surrounding area could be home to six of the state's nearly 20 microbreweries by next year, the Bismarck Tribune reported .

"It's definitely an exciting time to be a brewer," said Dylan Hilfer-Schafer, co-founder of Dialectic Brewing Co. in Mandan.

The craft beer industry is also increasing demand for locally grown ingredients.

Bismarck-based Two Track Malting Company started making craft malt barley in June 2016. It now has a waitlist and recently doubled its production from 5 tons (4.5 metric tons) of malt each week to 10 tons (9 metric tons).

Co-owner Jared Stober said the company sells its Two Track malted barley to brewers in 23 states.

"We've got that much interest," Stober said.

Ted Hoffman founded the North Dakota Brewers Guild, which first started with four brewers and has since grown to a dozen.

He said bars are now asking for 5-gallon (19-liter) kegs rather than 16-gallon (61-liter) kegs because they want to put more beers on tap from the growing number of local craft breweries.

"That's been a big change for us," said Hoffman.

For Hoffman, there will be more opportunities for customers to try quality locally-made beer. "The best is yet to come," he said.
