Online stores such as BirchBox.com and Vat19.com also sell sets of whiskey stones. The BirchBox.com stones are made by Teroforma. The site includes user reviews of the whiskey stones. Birchbox.com offers free returns within 90 days of purchase and free samples in the shipment. UncommonGood.com and Amazon.com also sell Teroforma Whisky Stones?. Both websites have user reviews. Amazon.com advertises free shipping if a minimum order amount is met, though the stones alone do not meet this minimum.
Whiskey stones are milled from a select grade of soapstone mined only in Vermont. Using soapstone cubes to chill whiskey prevents water from diluting the spirit. Soapstone is also dense enough that it doesn't absorb the whiskey. The stones have to be chilled for four hours in the freezer before putting into a drink.
