Chalkin' it Up

Regardless of what type of party you're at, there is usually some sort of beverage tracking system in place. In college tracking typically appears in the form of sharpie'd names on keg cups or even a distinguishing beer cozy. Post college this may eventually morph - into the seemingly more mature - holiday charms on wine stems.

Until now.
