Gammel Ålbo Camping near the Little Belt in Denmark has sunk 400 bottles of spirits to the seabed in collaboration with Trolden Destilleri as part of its 75th-anniversary project. According to campsite owner and manager Martin Pedersen, buyers receive ownership of a bottle that will mature on the seabed until June next year. They can retrieve it on 26 June 2027 by diving, snorkelling, or with assistance from divers. Sales began in early August, and about half of the 400 bottles have been sold so far.
