Our added value
Among the more commonly analysed contaminants responsable for organoleptic deviations in your wine are ; TCA (2,4,6-Trichloroanisole), TeCA (2,3,5,6-Tetrachloroanisole), PCA (Pentachloroanisole) and TBA (2,4,6-Tribromoanisole). These molecules known as haloanisoles can occasionally be found in dry wood. They are organo-halogenic compounds that can have an adverse effect on the contents of barrels.
To avoid any potential problem, we have decided to work in collaboration with the experts at the Excell laboratory (and its founder, Pascal Chatonnet), the only professionals able to interpret the results of analyses on sample water conserved after scalding the barrels, a new process they have patented.
This analysis is the only real answer to any contamination problems as “an analysis performed only on random samples of wood is not representative of the total surface of wood in contact with the wine.”
Thus the laboratory awards each finished product leaving the TONNELLERIE BERGER an individual certificate of non-contamination confirmed by the Excell Inspection label.
For our export orders, as well as the above analysis, we have chosen to analyse the air in the containers. The permanent increase in international transport brings a potential risk of toxicological or organoleptic contamination. It is not rare to find traces of TCA and TBA in some containers, as well as solvents and hydrocarbon. First we check the whole container thoroughly. Then we place a fibre optic probe in the centre for 15 minutes and send it to the Excell laboratory, who rapidly return the analysis report and certificate.
Because our conviction is to supply you with barrels of irreproachable quality, we have chosen total transparency for our working relationship.
