I liked it because it relieves you from indigestion in about half an hour after you drink it (one shot is enough), the only negative is that at first its taste is a bit bitter, but over time you get used to it. For me, since I always eat late at night because of work, it's a lifesaver.

The best drink, you add 3 ice cubes of 20% Fernet and complete it with Coca Cola or lemon soda. (Fernet with mint goes better with lemon soda). This is how you drink it in South America
