In an effort to not miss anything delicious at a food festival, you might find yourself, say, devouring every course at a seated dinner after already having eaten all day long. Underberg bitters, which are made from aromatic herbs in Germany, are the perfect antidote for those occasions. "I'm a big fan of Underberg when I'm on an eating marathon," says legendary barbecue master John Lewis of the eponymous Lewis Barbecue in Charleston. "It's a digestif bitter that you can shoot after a big meal or in between events. Not only does it help calm your stomach, but the alcohol in it also gives you a little boost." Lewis adds that while the taste might take some getting used to, the beneficial effect is nearly immediate.
