O'Fallon Brewery: Fitz's Hard Key Lime

Official description from the brewery:
This fine craft ale is brewed with the same distinctive flavors of tart key limes and pure cane sugar found in Fitz’s Key Lime craft soda. Not too sweet, not too strong, just a tasty balance of fresh brewed ale along with the tangy flavors of key limes all in one bottle. Serve ice cold with a fresh lime wedge. Enjoy!
