Jägermeister 9556 Nights of Exploration One barrel in Jägermeister’s barrel warehouse is very special because it was sealed over 25 years ago. The essence has been stored in it longer than in any other barrel before. Jägermeister has opened it now and produced a very limited edition from the exclusive liquid. Like the original, the herbal liqueur “9556 Nights of Exploration” is based on a secret recipe made from 56 natural ingredients such as herbs, flowers, roots and fruits. The maturing process of the base material over the past 25 years has been a journey of the senses: the smell, taste and appearance have changed several times until they were finally perfectly balanced with newly created flavours. The limited edition is available worldwide in an edition of only 2,500 hand-numbered copies.
