New Grist by Lakefront Brewery.

A deliciously bitter hoppy piece of joy for those of us who have celiac disease and are barred from our beloved reds...

"BEER: now cheaper than gas! Drink, don't drive."

(Other people besides me have begged the makers of Fat Tire to do a gluten-free beer, but they say that it's just impossible for them to avoid cross contamination in their plant. Very sad, because I'd really like to support New Belgium for all their bike advocacy.)
