"Double distilled" refers to a process in which a liquid, typically a type of alcohol like whiskey or vodka, is distilled twice. The first distillation separates the alcohol from the mash or wash, while the second distillation further purifies the alcohol, removing impurities and enhancing flavor. This method often results in a smoother and more refined product. The double distillation process is commonly used in the production of high-quality spirits. By increasing the alcohol concentration and improving the overall taste, double distilled beverages are often preferred by connoisseurs and are associated with premium brands in the spirits industry.
