Zwack disappeared from the American market for some time, but now its making a comeback. Unfortunately, not a lot of people are familiar with the product right now, and the most common comparison I hear being made to Zwack is Jagermeister. To me, I think that is a bit shortsighted, both liqueurs stem from a long European tradition of herbal liqueurs, and while there are some similarities in flavor, I find Zwack to have a very pleasant sweet cinnamon flavor that finishes with just a bit of citrus peel on the tongue before it disappears. All in all, a pleasant liqueur to sip neat (although I have been hearing rumors that Zwack and Red Bull is replacing Jager and Red Bull as the drink of choice amongst a certain set of people), and it mixes well. Don't believe me? Try this cocktail at home to see the versatility of Zwack in cocktails.
