As one Twitter-goer pointed out, the 250-barrel brewhouse is bigger than most Chicago-area breweries combined, including Goose Island. Construction is expected to be completed by July 2013 and cost $15 million - $18 million, with an eventual 600,000-barrel capacity to exactly mirror the Petaluma facility. By the time Lagunitas Chicago is ready to mash in in late 2013, they plan to move about 140,000 barrels of production there.
