An excellent mule as the lime goes well with the cachaca (although I used Husk cane spirit from tumbulgum in Queensland). I also squeezed half a shot of lime in to go with the cachaca.
If you are a big fan of both cachaca and ginger beer, you'll likely enjoy this - flavor is cachaca with loads of spicy ginger. But, I'm not a big cachaca fan, and think this is one and done for me.
