It’s confirmed through this Twitter feed from Tony Magee, Lagunitas Brewing owner (born in Chicago).

Beerpulse and New School Beer report that it will be a 250-barrel system by ROLEC.  The first mas is expected to take place at the end of 2013.

We’ll update this post with whatever new information we get, and later on today we’ll see what we can’t glean from the online property records for this facility down near Douglas Park where the brewery is said to be sited – right down near the studio where they film Boss.
