It’s easy to be tempted by whiskey stones. They’re all around us—lurking in the artfully curated checkout line of your local kitchen or design store, and front and center on Father’s Day gift guides. Whiskey stones—cubes of soapstone or metal that are stored in the freezer and used to chill drinks—can seem like the perfect add-on to go with the bottle of Scotch you got your dad; they're right there in the checkout line and they're so nice-looking with their sleek, geometric design. So innovative. So stylish. Your dad will love that he can chill his drink without diluting it with water.
