Since 1874, each generation of cellar master has selected the oldest and best eaux-de-vie for Louis XIII from the House’s cellars. As the cellar master may never taste the final blend for which some of these eaux-de-vie are intended, each cellar master must also carefully train a successor. The House's current cellar master, Baptiste Loiseau, joined as an apprentice to the previous cellar master, and then assumed the position of cellar master in 2014 at the age of 34.
