Andrew Hellman is a fan of single malt scotch, he is also a co-founder of Teroforma. Andrew was looking for a way to cool his drink without diluting it with ice.
After much research he came up with Whisky Stones, made from Vermont Soapstone. Due to soapstones natural softness (it won’t scratch the glass) and its unique ability to retain temperature for extended periods of time, it was the perfect answer.
Store them in the freezer and when you need ice for any drink (spirit or soda) they will be ready to go.
I own a set & love them! They are $20.00 for a set of nine. You can find them here.
