Jagermeister has 56 ingredients, which are a combination of
roots, herbs, flowers, fruits, barks and other forms. A proportion
of the ingredients can be viewed at the distillery, others can be
guessed at, but the recipe is a strongly guarded secret. In the
stores at Wolfenbutel there is a room containing the most secret
ingredients, the ordering, delivery and handling of which is
strictly limited to two or three people. I am aware of a number of
the important ingredients, but bear in mind some of these plants
may feature as flower or seed or root, or a combination thereof. I
am fairly sure of these:
Ginger, orris, galengal, lovage, chiretta, angelica, elecampane,
hyssop, pomerance, camomile, lavender, coriander, pepper, cloves,
star anis, allspice, nutmeg, cardamon, fennel, bitter orange, rose
hips, quinine, licorice, tumeric, mace, saffron.
These are possibles: marshmallow, yarrow, burdock, curcuma,
grains of paradise, cubeb, wintergreen, cassia, betony, purslane,
borage, sandalwood.
Deer blood is a myth. Caramel is used as a sweetener. Your real
problem is getting the proportions right.
