CHICAGO (WLS) --One of Chicago's biggest breweries has announced a recall of beer.
Revolution said it is recalling batches of beer produced with their house ale yeast that "do not meet our brand specifications for taste and flavor."
Affected brands include Anti Hero IPA, Fist City Pale Ale, Cross of Gold Ale, Mosaic Hero IPA, Eugene Porter, and Unsessionable Imperial IPA. Revolution said there are no health or safety risks involved with the consumption of the beer.
"This is strictly a quality issue," a brewery news release said.
The brewing company says the beers have the taste of Belgian ales, when they should only taste like American ales.
"We believe these off-flavors were produced by a wild yeast that has gotten worse over time and was not identified in time by our quality control methods," the release said, adding the problem has been resolved.
With fresh beer being packaged starting this week, Revolution said, their distribution network will begin working to replace beer immediately.
The affected batches have the following package dates (found on the bottom of cans, on the labels of bottles, and printed on kegs):
Anti Hero IPA 8-5-16 to 10-11-16
Fist City Pale Ale 8-11-16 to 9-26-16
Cross of Gold Ale 8-23-16
Mosaic Hero IPA 8-16-16 to 9-8-16
Eugene Porter 8-3-16 to 10-6-16
Unsessionable Imperial IPA 9-27-16 to 10-7-16
The product removal does not affect Oktoberfest, Rev Pils, Citra Hero, Rosa Hibiscus Ale, and Bottom Up Wit beers.
Consumers who are in possession of the affected batches of Revolution Beer can exchange it for fresh beer only at the Revolution Tap Room at 3340 N. Kedzie in Chicago.
"We sincerely apologize for the inconvenience this has caused for Revolution beer drinkers. Thank you to all the Revolution fans who have helped us identify this issue with our beers, and thanks to everyone for your support," the release said.
