Analysis of thujones in the alcohol analysis laboratory

Thujone is an active substance found in wormwood. It has two natural stereoisomeric forms, α- and β-thujone. It is this molecule that made absinthe famous, because it is said to have caused the side effects that led to the temporary ban on the beverage in the 20th century. In Europe, the total concentration of the two isomers in spirit drinks such as absinthe is regulated. It is limited to 35 mg/l.

WESSLING supports producers of absinthe and other spirit drinks by providing analysis of alpha and beta thujones in its alcohol laboratory near Paris.

Our laboratory is authorised by the INAO (the National Institute of Origin and Quality) to carry out such analysis, which is prescribed by the specifications as part of official testing and certification in terms of quality and origin.
