http://www.vat19.com/dvds/whiskey-stones.cfm?adid=youtube Whiskey Stones are cubes of solid soapstone that will chill your liquor without diluting it. Unlike ice, Whiskey Stones are non-porous and are thus odorless and tasteless. So, adding Whiskey Stones to your favorite bourbon will chill the spirit without affecting its taste. Because soapstone retains its temperature longer than ice, Whiskey Stones provide for a more sustained chill. Softer than granite, soapstone won't inadvertently scratch your glass. Hand-crafted in Vermont in America's oldest soapstone workshop, Whiskey Stones are the perfect gift for the refined connoisseur of spirits.
