Bitterness is one of the most important taste components in the world of beverages, especially in liqueur making. In the food and beverage department of the hotel industry, understanding bitterness is essential because it plays a major role in flavor balance, cocktail creation, and guest satisfaction. In simple terms, bitterness refers to a sharp, slightly harsh taste that is often derived from natural plant compounds such as roots, bark, herbs, and spices.
The concept of bitterness has been used for centuries in drink preparation. Historically, many bitter substances were used for medicinal purposes. In fact, the word “bitters” comes from early herbal tonics that were designed to aid digestion and improve health. Over time, these medicinal preparations evolved into flavorful ingredients used in liqueurs and cocktails.
In liqueur making, bitterness is not meant to overpower but to balance sweetness. Most liqueurs are sweet by nature because they contain sugar, fruits, or syrups. Without bitterness, these drinks can taste too sugary and unpleasant. Bitterness adds depth, complexity, and structure to the drink, making it more enjoyable.
In French terminology, bitterness is referred to as “amertume”, and bitter liqueurs are often called “amer”. These terms are widely used in the global beverage industry, especially in fine dining and luxury hotel environments.
Today, bitters are used in a variety of applications, from classic cocktails to modern mixology. According to industry estimates, over 70% of classic cocktails include bitters as a key ingredient, showing their importance in beverage preparation.
Definition and Origin of Bitters (Les Amers)
Bitters, or “les amers” in French, are concentrated alcoholic extracts made from botanical ingredients such as herbs, spices, roots, fruits, and bark. These ingredients are infused into alcohol to extract their flavors, especially the bitter compounds.
The origin of bitters dates back to ancient civilizations like Egypt and China, where herbal infusions were used for medicinal purposes. However, modern bitters became popular in Europe during the 18th and 19th centuries. Apothecaries (early pharmacists) created these mixtures to treat digestive problems, fever, and other illnesses.
One of the earliest commercial bitters was developed in the early 1800s, and it quickly became a staple in both medicine and hospitality. Over time, people began to enjoy the taste of bitters, and they were incorporated into alcoholic drinks.
Bitters typically contain a base spirit (like ethanol), a bittering agent (such as gentian root), and flavoring ingredients (like citrus peel or spices). The alcohol content usually ranges from 35% to 45% ABV, making bitters quite strong, but they are used in very small quantities.
In the hotel industry, bitters are considered essential tools for bartenders. They are often described as the “salt and pepper” of cocktails because they enhance and balance flavors.
Role of Bitterness in Liqueur Making
Bitterness plays multiple roles in liqueur production, making it a key component in beverage formulation. The main function of bitterness is to balance sweetness. Since most liqueurs contain a high level of sugar (sometimes up to 250 grams per liter), adding bitter elements prevents the drink from becoming overly sweet.
Another important role of bitterness is to add complexity. A good liqueur should have multiple layers of flavor. Bitterness interacts with sweetness, acidity, and aroma to create a well-rounded taste experience.
Bitterness also stimulates the appetite and aids digestion. This is why many bitter liqueurs are served as aperitifs (before meals) or digestifs (after meals). In French, these are called “apéritif” and “digestif”, respectively.
From a sensory perspective, bitterness activates specific taste receptors on the tongue. These receptors are highly sensitive, which means even a small amount of bitterness can have a strong impact.
In modern mixology, bitterness is used to create contrast and balance. For example, in cocktails like Negroni or Old Fashioned, bitters play a crucial role in defining the drink’s character.
Types of Bitters Used in Liqueur Making
Bitters can be classified into several categories based on their flavor profile, ingredients, and usage. Each type has a unique role in liqueur making and cocktail preparation.
Aromatic Bitters (Amers Aromatiques)
Aromatic bitters are the most commonly used type in the beverage industry. They are made from a blend of herbs, spices, and roots, resulting in a complex and spicy flavor profile.
These bitters are often used in classic cocktails. They typically include ingredients like clove, cinnamon, cardamom, and gentian root. Aromatic bitters are essential in drinks like the Old Fashioned.
They are known for their warm and intense flavor, which enhances the depth of the drink. In hotels, bartenders rely heavily on aromatic bitters for traditional cocktail recipes.
Citrus Bitters (Amers aux Agrumes)
Citrus bitters are made using the peels of fruits like oranges, lemons, and grapefruits. They have a fresh, zesty, and slightly bitter taste.
These bitters are ideal for light and refreshing cocktails. They add brightness and enhance the aroma of the drink.

The production of bitters involves several steps. First, the botanicals are selected and prepared. These ingredients are then soaked in alcohol in a process called maceration.
After maceration, the mixture is filtered to remove solid particles. The liquid is then aged to develop flavor.
In some cases, sugar or caramel is added to balance the bitterness. The final product is bottled and ready for use.
This process can take anywhere from a few weeks to several months, depending on the desired flavor.
