Curt Mast felt that a high-quality stable bottle was important for his fine herbal liqueur. The model he ended up choosing would become the distinctive green Jägermeister bottle.
He first put a number of different possible bottle models through a breakage test. At home in his kitchen, Curt Mast dropped one bottle after the other onto the wooden floor from a height. A rectangular model, whose glass colour was initially transparent, proved to be especially robust. In order to strengthen the reference to hunting, the bottle was produced in hunter green. A positive side effect: the dark green glass is opaque to most UV rays and thus protects the precious herbal liqueur.
The production of the angular, green bottle is an expensive undertaking even today, because it is more difficult to shape than an ordinary round bottle. It is manufactured at over 1,500 degrees Celsius and is subjected to a another visual inspection prior to bottling.
