GRAND RAPIDS -- Ben Fleckenstein, co-owner of the one-year-old Paw Paw Brewing Co., said he had no idea what he was in for when he signed up to take part in the seventh annual Michigan Winter Beer Festival.

Along with brewer and co-owner Ryan Sylvester, the duo build their own portable booth, which could be broken up into six pieces, to promote their beer to the more than 6,000 people who attend the event at the Fifth Third Ballpark in Comstock Park, near Grand Rapids. A lot of people at the chilly celebration of craft beer, had no idea Paw Paw existed.

"We get a lot of people asking and they don't believe, 'Wait, Paw Paw is a city?'" Fleckenstein said.

Paw Paw Brewery made a nice visual splash with its stickers, which were placed on glasses, hats, mittens and jackets of those who visited the booth, located near the entrance. One of the brewery's regulars surprised them with 10 rolls of stickers and told them to hand them out at the festival, which featured more than 450 beer from more than 60 breweries, including those in the Kalamazoo area, such as Bell's Brewery Inc., Olde Peninsula Brewpub, Arcadia Brewing Co., Dark Horse Brewing Co. and more.

"We feel like the reception has been overwhelming, especially amongst so many fantastic beers. It's just exciting to be here," Fleckenstein said.
