The alcohol content of Underberg is 44% ABV (Alcohol by Volume), making it significantly stronger than most wines, beers, and many traditional liqueurs. This high alcohol percentage ensures that the herbal extracts used in its formulation remain potent and effective. The 44% ABV classifies Underberg as a high-proof herbal spirit, yet it differs from whiskey, vodka, or rum because it is intended to be consumed in small portions rather than large servings.
Each single-serving bottle of Underberg contains 20 mL (0.67 fl. oz.) of liquid, meaning that despite its high alcohol percentage, the total alcohol intake per serving is relatively low. Unlike standard spirits, which are often poured in 1.5 oz (44 mL) shots, Underberg is specifically designed to be consumed as a digestif in controlled portions. This makes it less intoxicating than other strong spirits when consumed in moderation.
Compared to other well-known digestifs and herbal liqueurs, Underberg is notably stronger. For example, Jägermeister contains 35% ABV, and most Amaro varieties range between 20-30% ABV. Unlike these sweeter digestifs, Underberg has no added sugar, making it bitter and medicinal in taste rather than smooth and syrupy. This intense flavor and high alcohol content set it apart from other after-dinner drinks, making it a favorite among those who appreciate strong herbal flavors and potent spirits.
Underberg’s 44% ABV serves a functional purpose beyond just making it a strong beverage. The high alcohol content helps to extract, preserve, and carry the essential oils, bitter compounds, and active ingredients from the 43 different herbs and botanicals used in its recipe. These ingredients are sourced from different parts of the world, ensuring a rich, complex herbal profile that is both medicinal and aromatic. The alcohol acts as a solvent, helping to release and maintain the potent properties of the herbs, which contribute to the drink’s digestive benefits.
The high alcohol percentage also plays a role in Underberg’s effectiveness as a digestif. Herbal bitters have long been used to stimulate the digestive system, promote enzyme production, and ease bloating or discomfort after heavy meals. The combination of alcohol and herbal extracts in Underberg allows it to be absorbed quickly, making it a fast-acting digestive aid. Unlike traditional liqueurs, which contain added sugars that may slow digestion, Underberg’s pure herbal formula and high alcohol content make it particularly effective.
Despite its strength, Underberg is not typically consumed for intoxication. Because it is packaged in small single-serving bottles, it is meant to be enjoyed in moderation rather than in large quantities. Its primary purpose is to aid digestion, and its intense bitter and herbal flavors make it less likely to be overconsumed compared to sweeter, lower-alcohol liqueurs.
Unlike many other spirits and bitters, Underberg is not meant for casual sipping or cocktail mixing. Instead, it is designed to be consumed in a single sip straight from the bottle, allowing the drinker to experience its intense herbal flavors and digestive benefits. Since each bottle contains a measured 20 mL serving, there is no need for additional measuring or pouring. Simply twist off the cap and drink it in one go.
While Underberg can be chilled or enjoyed at room temperature, the traditional method is to drink it at room temperature to fully appreciate its complex herbal aromas and warming effect. Some people prefer it cold, as chilling the liquid can slightly mute the bitterness and create a smoother experience. However, the digestive benefits remain the same regardless of temperature.
The best time to consume Underberg is immediately after a meal, especially if the meal is heavy, fatty, or rich in protein. The bitterness and high alcohol content help stimulate digestion, which is why it has been traditionally used as a post-dinner drink in many cultures. Some people also enjoy Underberg as part of a bitters tasting experience, comparing it with other digestifs like Amaro, Fernet, or Chartreuse. However, due to its distinctively bitter profile, it is an acquired taste best suited for those who appreciate intensely herbal and potent spirits.
Unlike other bitters, Underberg is rarely used in cocktails because of its strong and concentrated flavor. While some bartenders have experimented with adding it to craft cocktails, it is generally best enjoyed on its own as a pure herbal digestif.
Underberg contains 44% ABV (Alcohol by Volume), making it stronger than most liqueurs and bitters. However, because it is consumed in small 20 mL servings, the actual alcohol intake per bottle is moderate.
