Hang a bag, stainless hop ball, or oak strip from this tab that is welded onto the bottom of a keg lid. This is a product to use for aging your beer on oak cubes, dry hopping, adding cacao nibs – any post-keg addition of ingredients you can think of! To use, simply thread the string of your hop bag into the hole and tie off. When it is time to remove your adjunct/hops, pull the lid off of the keg and replace with a normal one. This really enables you to control the exact time your beer sits on the hops, oak, etc. and makes their removal a cinch!
