ROCKFORD — MittenBrew.com, the leading source for Michigan craft libation news, reviews and event coverage, has announced it has teamed up with Rockford Brewing Company to release its second collaborative beer.

The beer, named Grandma’s Cookies, will be released at a Feb. 24 release party at Rockford Brewing Company beginning at 5 p.m. The party will be open to the public at no charge.

In addition to Rockford Brewing Company, the beer will be made available at the Michigan Brewers Guild Winter Beer Festival, held Feb. 27 and 28 in Comstock Park. Grandma’s Cookies will also be available on tap at several beer bars throughout Michigan beginning March 2.

Additional release parties are also being planned the first week of March. Details for these parties will be finalized in the coming weeks.

“I was thinking about making an oatmeal raisin cookie beer for a long time,” said Jeff Sheehan, co-owner of Rockford Brewing Company. “We discussed it, and the suggestion came up that we make a beer that tastes like cookies without actually using cookies. That was a good direction to go.”

The oatmeal raisin cookie beer is classified as a dark amber ale, and will clock in between 6 and 7% ABV.

Members of the MittenBrew.com team joined Rockford Brewing in late January for the brew day, led by lead brewer Brian Roeters.

“We decided to use grains that contribute that dried fruit or raisiny type character to the beer so it will have that taste without actually raisins. There are oats in the beer as well, and a touch of cinnamon,” said Sheehan.

“We couldn’t be more excited to be working with RBC on this collaboration,” said Bryan Esler, partner at MittenBrew.com. “As we’ve grown over the past few years, we’ve always wanted to think outside the box on how we approach our collaborations.”

The beer follows in the footsteps of Nutter Berry Wheat, a 2013 collaboration between MittenBrew.com and Saugatuck Brewing Company.

MittenBrew.com plans to release a different branded beer twice a year, and plans are already underway for a fall release.
