These keg filler stickers are designed to help you quickly check the fill volume, especially when filling cold beverages like cold-crashed beer. When the liquid inside is cold, the color changes from yellow to green. For 5-gallon kegs, you will need to apply 2 stickers if you want the gauge to run the full length of your keg.
