Bierwurst is a sausage which tastes similar to Jagdwurst. However, it is much larger. It is often flavored with garlic. If it has bits of ham in each slice it is called Bierschinken (Schinken = ham).
Jagdwurst is a sausage made with sizeable pieces of pork fat and rosy pork meat, embedded in a pale, pink pate base. It is slightly porous.
