Yes, the festival has its own deposit cup system.
At the festival bars, you can purchase a deposit cup for €2, which will be your key to enjoying any drink within the festival grounds. If you already have a cup from previous years, feel free to bring it along, refill it, or exchange it for this year’s cup.
You will be able to exchange your deposit cup at the festival INFO tent and check-in points.
