Is this a gimmick based on a cold brew fad? Probably. But who cares? What matters is if the final product is any good. To that point I followed the instructions in the back of the bottle and put the mini in the freezer and served it ice cold. The aromas are quite peculiar. You have the usual suspects standing out as you'd expect from regular Jager--anise, caramel, an assortment of spices--but there's some interesting things going on as well. It doesn't just smell like Jager plus Coffee. It has a more earthy, "grounded" scent. Whereas regular Jager is a bombardment of scents this feels like they all settled down and found their bearings. It's a bit of a silly description I'm aware but I have no other way to describe it. More interesting than the earthy undertones are a peculiar spicy note. I even looked up to see if any hot peppers had been added. It's quite a potent spicy layer that stands out against the harder to pin down herbal scents. Taste wise the anise leads the charge followed by the plethora of herbals that define a regular Jager shot but then cinnamon and allspice enter the fray along with this bizarre but pleasant flavor. It's the spice note I detected but it doesn't taste spicy. More like wood bark with a kick? I am as confused as you are dear reader. It's a good flavor though. The finish is dominated by cocoa and then the Arabica coffee with the herbal and root flavors of regular Jager complimenting the finish in rather playful ways. I'm legitimately shocked at how good this tastes. Regular Jagermeister is a hard liqueur to work with. You can make some interesting cocktails if you know what you're doing and as a cold shot it's a fun gimmick but you either hate it or love it. This though? It's what I always wanted a Jagershot to be like and I can see myself buying the full 750 mL bottle and keeping it chilled. It works way better than it has any business to. From here on out if I'm doing chilled Jager shots, it's going to be the cold brew version. Cheers!
