Oak chip infusions (or boisés) are used to provide complementary tannins to products which are aged in casks or barrels. They are made solely from French oak from the renowned Limousin and Allier regions. In accordance with current legislation, they are perfectly natural and contain no artificial preservatives.
The infusions are made by macerating oak chips in water which is brought to boiling point.
Evaporation is carefully controlled to obtain the desired concentration. The oak which is used is carefully matched to the oak selected to make the barrels in which cognac is aged.
| The Pecner company produces two types of boisé : | |
 |
The oak chip concentrate which is produced without alcohol, for using directly after distillation with eaux-de-vie which will take on little tannin. |
| |
The oak chip water complement, with no alcohol, for using with aged cognac to bring down its level of alcohol - just as water is used - but with the advantage of providing oaky qualities. It is incorporated immediately. |

The Pecner company, keen to further its export potential, has developed an atomised version of its oak chip complements, especially for lengthy transportation : it is compact, completely stable, easy to use and with no risk to its keeping qualities.
