Fusel oils are natural compounds that form during the alcohol-making process. Think of them as side products that appear when making spirits like whiskey or rum. For distillers, understanding fusel oils is important because these compounds can affect how the final drink tastes and smells. Some distillers work to reduce fusel oils (when making vodka, for example), while others maintain certain levels to create specific flavors (like in whiskeys). It's similar to how a chef needs to understand different cooking techniques to create the perfect dish.
