I am actually working to refine the process and be able to make more. I am going through and making labels according to the BJCP guidelines and color coding them base on style (pale, light an dark categories)
I just wanted to jump in here and say I bought a set of these (magnetic) for my kegerator (once I get it finished)! They are AWESOME. I now have a label for each BJCP style! I like the simplicity of it. Keep them all stored on the side of the kegerator and just pick-and-place the one for the beer you are serving.
I would recommend them if you appreciate simplicity and want to identify the style being served. It's a much cleaner solution than chalk board or dry erase board...
