Bitter liqueurs are quite famous, especially those from Italy, such as amaro, and France. These liqueurs are made in various regions throughout these countries and are made from secret recipes of herbs and spices - some local, many imported from other territories. The herbs and spices include things such as orange peel, rhubarb, pomegranate and tree bark. Quite often these are mixed with fruit juices for pre-dinner cocktails, while most examples of amaro are enjoyed straight, often as a digestif. Alcohol levels are usually around 20% to 25%.
