Bitters are an aromatic flavoring agent made from infusing roots, barks, fruit peels, seeds, spices, herbs, flowers and other botanicals in a high proof alcohol. Bitter herbs, barks and botanical tinctures have been made for centuries dating back to the 1600’s and have been reputed for possessing medicinal properties. Before bitters were added in dashes to cocktails they were being drunk in larger amounts as a patent medicine. Bitters were used as a cure for many different ailments from headaches to stomach cramps. Bitters can still be used as an herbal medicine! When I have a stomach ache I will add four to six hefty dashes of bitters to soda water and it certainly has restorative powers.
