In 1901, the Pernod factory - the largest absinthe distillery in the town - fell victim to a fire. With the alcohol reserves representing a risk of explosion, an employee decided to empty the reservoirs into the Doubs. Legend would have it that the merry inhabitants would drink the water straight from the river. However, these events led to a hydrological discovery: the first colouration in history. We discovered that the Loue was a resurgence of the Doubs, as it waters had taken on the same murky colour and aniseed smell.
