The Give a Craft beer trail starts on May 28.

KALAMAZOO, MI -- Craft beer lovers in Kalamazoo soon will be able to visit all 11 of Kalamazoo County's breweries and complete a "passport" to receive free swag.

The Give a Craft beer trail will launch May 28.

The trail was designed by Discover Kalamazoo to promote the county's breweries. People who participate in the trail will use a "passport," which will include information about each brewery, such as tour information, hours of operation and seasonal favorites. Participants will visit each brewery and have the passport stamped.

After acquiring stamps from all participating breweries, participants can turn their completed passport in to Discover Kalamazoo for a stainless steel beer bottle opener. For extra swag, participants can stop at Bell's Brewery Inc.'s Comstock brewery to earn a pair of Bell's sunglasses.

There is no purchase necessary to collect passport stamps at any brewery.

Give a Craft passports can be picked up at any of the participating breweries, at Discover Kalamazoo or at the information desk at the Kalamazoo/Battle Creek International Airport.

Renee Newman, Discover Kalamazoo vice president of marketing and communications, said the beer trail was designed after other beer trails throughout the country, especially the Bend Ale Trail in Bend, Oregon.

"This for us is a way to promote the (nearly) 12 breweries that we have here in Kalamazoo and get people moving around in our community," Newman said.

Newman called it a "self-guided exploration of our county breweries."

There is no time limit for the trail to be completed, though Newman noted the swag is limited in quantity.

Newman said an idea for the beer trail has been brewing for about a year at Discover Kalamazoo.
