The Danish Agriculture and Food Council came up with the idea to gather the urine from the festival in 2015 to use as a fertilizer on malt barley fields in the Danish town of Køge.
And it's this barley that has now been made into beer. 54,000 litres of urine, released from the bladders of festival goers, has found its way into 60,000 bottles of beer.
Although the creators have no more plans to brew Pisner, we would not be surprised if this beercycling concept takes off.
Sustainable, organic and apparently no "pi**y" taste, is this the ultimate in exclusive hipster brews?
The Pisner will be available in selected supermarkets and cafes in Denmark in June. Unfortunately - or perhaps, fortunately - with such limited supply New Zelanders are unlikely to get a taste.
