I generally don’t cool whiskey. Sometimes a splash of water but that is about it. But since the Nesh Whiskey Chiller can take a liquid from room temperature to 36 degrees in 15 seconds, It just might solve the issue of recently purchased beer that has warmed up on the way home from purchasing.
The science is that “the area around the coils is frozen solid – exposing your whiskey to 3 feet of ice as it pours through while remaining isolated in a stainless steel tube. This significantly reduces the temperature of the spirit without directly exposing it to ice or water.”
Might be interesting to experiment with.
