I know what you're thinking: Why the heck do I need a decanter? The vessels are usually reserved for wine and whiskey aficionados – you know, those who can actually tell when they're drinking high-quality booze. By allowing oxygen to interact with the drink, it's basically letting it "breathe" so the aromas and flavors are released. Not exactly a priority if you drink pretty casually, but a good decanter can look really nice propped up on a bar cart. You don't even have to actually use them!
