Revolution Brewing is going macro.

The Chicago brewery, known for its now-ubiquitous Anti-Hero IPA, is more than tripling capacity, adding a 120-barrel brewhouse, several 800-barrel fermenters and other equipment to its Northwest Side production plant.

Revolution said the expansion will eventually boost capacity to 300,000 barrels annually, up from about 75,000 barrels today. Established in 2010, fast-growing Revolution made just more than 50,000 barrels in 2014. (One barrel is equivalent to 31 gallons, or about 331 12-ounce cans.)

The added capacity will be built out in the same building of its existing production brewery and taproom at 3340 N. Kedzie Ave. in the Avondale neighborhood, bringing the space to 90,000 square feet, up from 60,000 now.

The expansion will add more kegging, bottling and canning lines, enabling Revolution to introduce more beers to its retail lineup. That includes Fist City, a year-round pale ale initially introduced in collaboration with restaurant Big Star that's slated to hit shelves in 12-ounce cans in April.

Additional space also will make way for more cold storage to keep beer fresh for distribution.

“Chicagoans are enjoying a lot of Revolution brews, and this expansion project gives us the ability to keep that beer flowing for many years,” Josh Deth, Revolution's founder and managing partner, said in a statement.

To put its new size in perspective, Illinois' 83 craft brewers combined produced 137,000 barrels of beer in 2013, the latest full year for which data are available, according to the Brewers Association, a trade group. That, of course, came before Petaluma, Calif.-based Lagunitas Brewing opened its giant brewery at 1843 S. Washtenaw Ave. last year. With its 300,000-square-foot production house with capacity to eventually produce up to 600,000 barrels a year, Lagunitas instantly became the state's largest brewer.

Revolution doesn't appear to be too far behind. The nascent brewery quickly grew out of its original production facility and brewpub at 2323 N. Milwaukee Ave. in Logan Square as brands like its robust, hoppy Anti-Hero, the chocolatey Eugene Porter and its Belgian-style Bottom Up Wit struck a chord with Chicagoans. Revolution launched a 40,000-square-foot Avondale brewery in 2012 and a year later expanded it to double capacity. It also began distribution in Ohio.

The brewer plans to add 15 full-time employees within the next two years, bringing its workforce to about 180.

It is financing the expansion with loans from First Midwest Bank and SomerCor 504, the group that helped finance its original brewpub.
