So I was wrong. Indeed: "Akvavit, like vodka, is distilled from either grain or potatoes. It is flavoured with herbs such as caraway seeds, anise, dill, fennel, coriander, or “grains of paradise.” The Danish distillery Aalborg makes an akvavit distilled with amber."
It is not just the jubilee. I read all the akvavitter have a more or less light golden color.
