Here is what I could find for ya..I personally don't know but what I found this is the best explanation
Braunschweiger and Liverwurst are often used synonymously. In terms of their difference, following opinions (sometimes even conflicting) are what you could find:
- Braunschweiger is actually a more specific term for one (the most popular) type of Liverwurst, while Liverwurst is referred to as a general term for sausage with pork liver in it.
- Liverwurst is a spreadable sausage. Braunschweiger is sliceable rather than spreadable. Or the opposite.
- Liverwurst can be smoked or plain while Braunschweiger is nearly always smoked.
