Wait, is it Argentinean, or Argentine?  Whatever.  Fernet is Argentina’s drink, and with a little patience  you’ll learn to love it too.  When you first try Fernet it’s hard to see why it’s so popular.  Fernet is almost black, and has a really strong bitter-herby taste.  The closest comparison would be to Jager, but it doesn’t really taste like that either.  The most popular way to drink it is mixed with cola, about 50/50, with no garnish in a rocks glass.  After a while I really acquired a taste for it (persistence is the key), and added much less cola.  There is also a mint flavored version that would be perfect if you’re the type of self-hating masochist that likes menthol cigarettes.
