Clever.



But at £16 they are expensive and fairly pointless. A lot of drinks actually want a little bit of the ice to melt in order for the physical nature of the drink to change. For instance the Khymos blog suggests that adding ice alters the state of the whisky so that a new set of aromas emerge...

This is from the Mocha gifting website:

"Nordic Rock is mined from ancient Swedish pollution-free base rock. It is the purest way of cooling your drink - literally 'on the rocks'. Stone does not melt, which means no unclean water in your glass. They are also reusable making them very eco-friendly.

To use, simply place the stone ice cubes in the freezer for approximately one hour before use. For a normal glass, two or three Nordic Rocks will be fine. They give off their cold gradually and equally."
