Only two Chartreuse monks know the identity of the 130 plants, how to blend them and how to distill them into this world famous liqueur. They are also the only ones who know which plants they have to macerate to produce the natural green and yellow colours. And they alone supervise the slow ageing in oak casks. To bring out all its flavour, it should be consumed very cold, even on the rocks. Traditionally considered an after dinner drink, Chartreuse is more and more being enjoyed as a long drink.
