From the distiller's website:
In 1988, a directive from the European Council lay down the content to be respected regarding the differents products which are used in the making of food products. The thuyone content to be respected is 10 mg/kg for alcoholic beverages titrating more than 25 % proof in volume and 35 mg/kg for specific alcoholic beverages. Moreover, the 1915 decree prohibiting absinthe is still in force, that’s why none of the current producer of “absinthe” use the word absinthe.
The sale denomination of this beverage will have to obey the imposed rules. The use of the term “absinthe” is likely to create a confusion on the nature of the marketed product with the prohibited beverage resulting from the big wormwood (absinthe), so, it is advisable not to refer to the word “absinthe” but only to the extracts or bases of the wormwood plant.
The products manufactured this way are wormwood plants-based spirits. Moreover, the word absinthe must be written in the same font than “ .. –based spirits” to avoid any fraud towards the consumer.
