, Fernet Branca is definitely an acquired taste. However, those that like it tend to become die-hard fans of the product. If you're still on the ropes, Fernet Branca is often regarded as a cure for hangovers when mixed with espresso. That doesn't mean you can stay out until 3 a.m., drink one and be chipper for your 8 a.m. meeting, but it's nice to know you have an ally that can help relieve the regret. Plus, its 39 percent ABV gives you a bit of a jolt.
