Esters
Esters are natural compounds that create the fruity, floral flavors in alcoholic beverages. In the distillery and brewing world, they're like nature's flavor makers. When you taste banana notes in whiskey or fruity hints in beer, that's often from esters. Understanding esters is important for anyone making alcohol because they can control how the final product tastes. It's similar to how a chef understands spices - distillers and brewers need to understand esters to make their products taste right.
