In the category of wacky ideas, here is the idea of the Danish brewerNorrebro Bryghus. The latter had the idea of creating the first beer made from urine ! But do not worry, they did not inject urine, strictly speaking, of course. No, on the other hand, they launched the collect the urine of festivalgoers in order to use it as fertilizer to grow maltcereal which as you know is used to make beer.
And the bet was successful because they collected not less than 50,000 liters of urine and were able to make 60,000 bottles of their new beer. The latter is called Pisner, in reference to the piss and the Pilsner, a type of blonde beer.
A rather unusual idea which, it must be admitted, does not give not necessarily envy at first. But hey, in truth, the picture "Amiss" that consumers can have from this beer is obviously hypocritical when you know where the majority of fertilizers used in agriculture.
In any case, the concept has been pushed to the end. The bottle packaging has a small diagram symbolizing recycling with a man drinking a beer with ... his clearly visible attribute.
