-Energy City:
Hop Nawi New England-Style IPA.
-D & G Brewing: 
Kolsch - 4.5% ABV - Light in color, but big on taste. This beer is brewed primarily with Pilsner malt and a top-fermenting yeast. A light hop touch complements a clean finish. 

Roasted Chocolate Oatmeal Stout - 5.1% ABV - Dark and robust. This beer is brewed with no adjuncts (no chocolate, no coffee), the flavor and power of this beer come strictly from the liberal use of flavorful malts.

-Riverlands:
Murky Waters: Citrasaic - New England Style IPA - 7%abv. A Citra and Mosaic hopped juicy, hazy IPA with a soft, smooth body. Expect flavors and aroma of citrus, tropical fruit, and a bit of piney resin.
First Catch of the Day - Imperial Stout - 12%abv. A thick, chewy Imperial Stout aged with Vanilla, Maple, and Coffee from a local roaster, Casas Coffee. In addition to the added flavors, the stout base provides a full body with flavors of dark chocolate, dark fruits, and caramelized sugar.

-The Forge: Forge Fest Bier (Oktoberfest) and a new Brut IPA
