At the time I ventured into making the first batch of my own coffee liquor in the spring of 2011, there was a crack in one of the pipes leading drinking water to the northern part of Copenhagen where I live. The water was contaminated and everybody was freaking out buying up mineral water in the grocery stores, even though you could sterilize the water by boiling it. This lead to the scull logo on the label and a warning about it being tapped in Nørrebro.
