Why, you might ask, does Oskar Blues Home Made Liquids & Solids, a bustling Longmont restaurant owned by one of Colorado's most well-known craft breweries, offer Coors Light amid a draft lineup that not only includes its own stellar beers, but dozens of other craft-beer treats? Simple. It's an intervention. If you order a Coors, the bartender will bring you a taster of Mama's Little Yella Pils so that you can compare the two. The goal, of course, is to convince you to switch. It's the first step to better beer drinking.
