As the “merrains” have a high moisture level, a drying or “seasoning” stage is indispensable to achieve water content of about 15%.
As the woods dries, it shrinks and its volume decreases. Drying is therefore necessary before making the casks, in order to obtain boards that will not shrink once assembly is complete.
If the “merrains” are not dry enough, they continue to dry after the cask is completed, resulting in leaks.
However, the seasoning stage is generally longer, as the “merrains” mature.
This maturation has a positive effect on quality: it yields eaux-de-vie with a more supple mouthfeel and more distinct aromas.
