Two Brothers is one of the oldest craft breweries in Illinois; opening up in Warrenville - a far western suburb of Chicago (and a neighboring city to where I live) - back in 1996. Over the past twenty years, they have grown and grown at a huge rate. In fact, they are responsible for my first steps into craft beer. I loved their Sidekick, Outlaw, and Wobble so much that I began to try a ton of other IPAs from all over the country.
They now have a 40,000 square foot brewery/taphouse and three different locations; including a second brewery in Scottsdale, Arizona, and two high-end restaurant/bars in Aurora (Roundhouse) and Naperville (The Craftsman), Illinois.
