It is made with the same plants as the Chartreuse Verte, but in different proportions, it offers scents of flowers, honey and spices. Only two Chartreux Brothers know the names of the plants and know how to mix and distill them. They are also the only ones who know which plants to use to give natural green and yellow colors. It is they who control the slow aging of the liquor and decide when the liquor is ready to be bottled.
