I have a story in the new Fall 2013 issue of Whisky Advocate magazine that's not online. In it I compared a range of devices meant to chill down whisky.
- Teroforma Whisky Stones [buy]
- Teroforma Whisky Stones MAX [buy]
- Balls of Steel [buy]
- Skybar's Wine Chill Drops [buy]
- Tilt Spheres [buy]
- Steel Ice [buy]
- A glass put in the refrigerator
- A glass put in the freezer
If the story goes online, I'll share the link here.
