Many newbie bartenders and consumers get the words “liquor” and “liqueur” confusing, if not outright similar. In this blog, craft spirits connoisseur Adam Quirk of Cardinal Spirits explains the key differences between the two.
First off, liqueurs refer to beverages that have flavorings or are based on flavored or distilled spirits. Liqueurs are generally fragrant, come in vibrant colors, and have an alcohol content of between 25 and 55 degrees. While these concoctions are often mixed with fruits and herbs, some are made with cocoa, coffee, and other foods. Liqueurs are correctly consumed on small glasses at room temperature or while slightly cold.
Liquor or spirits, on the other hand, are a product of the chemical process known as distillation. The process entails heating a beverage comprised of water and alcohol to over 78.3 but below 100 degrees to prevent the mixed-in water from boiling. The alcohol then gets evaporated, separating from the original liquid and re-condensed to make for a stronger drink. Spirits usually have between 40 and 65 degrees of alcohol content.
Liquors are prepared from foods that contain natural sugars such as agave and sugar cane. Some of the most common ones are vodka, whisky, tequila, and rum. Again, liquors are created via distillation, following the process of fermentation similar to how beer or wine is made. The resulting distilled spirit—which will become a liqueur when added flavorings to—is then put into a still, with the alcohol extracted in often-high concentrations, aged, re-distilled, or watered down to the so-called “bottle strength.”
