I've been to a lot of beer tasting events over the last few years. At many of these events, your entry fee includes a 4oz taster glass, often with the logo of the group presenting the tasting. The problem is, everyone else at the event has the EXACT SAME GLASS. So, how to keep track of which glass is yours? You could never put it down, but there are notes to take, and food to eat, so you need both your hands. That's where these come in.
