These soapstone cubes from
Teroforma have been around for a bit, but I never understood the draw of making your whisky colder. Further I would say adding a splash of water is a good idea to get the nose going. It is a cool idea no doubt. HOHO! You almost missed that pun... Apparently this is a take on a Scandinavian drinking tradition. Anyhow, just thought of a use I can really get behind;
martini stones. Keep everything cold and no dilution. Just found this great video about The Vermont Soapstone Company in Perkins, VT that has benefited/survived due to this product. Have a look.
