I've never had good luck "reusing" the grogtag labels. That being said, I keep a few around that I use to label gift bottles. Other than that, I go with the "marker on the cap" technique. This year, I ordered some different colored caps from Northern Brewer. That way, I can color code them and be done with hit. Hopefully, I will have my keezer done for next year and I can quit this bottling nonsense!
