Applejack is a type of spirit that is made by freeze-distilling hard apple cider. This process concentrates the alcohol content, resulting in a stronger and more flavorful spirit. It has roots in American history and is commonly used in cocktails or enjoyed on its own as a sipping spirit. The alcohol content of applejack can vary widely depending on the brand and how it's made. Some applejacks are relatively mild, with an ABV (alcohol by volume) of around 30%, while others can be quite potent, with an ABV of over 50%. Be sure to check the label before you indulge. Applejack has a long history in the United States, dating back to colonial times. In fact, it was a popular drink among early American settlers, who often used it as a form of currency.
