Cling labels are a great option for reusable beer labels. They are made from a special vinyl material that adheres to glass without adhesive. This means that they can be easily removed and reused, and they won't leave any sticky residue behind.
Cling labels are also very effective at staying adhered to glass, even when the bottle is chilled or has condensation. The static cling properties of the vinyl material create a strong bond with the glass, even in cold or wet conditions.
I have used custom stickers for my own beer brewing, and I have found them to be very effective. They stay adhered to the bottles even after being chilled in the fridge, and they are easy to remove and reuse.
