Got this from a question and answer site I don't know where the ice-bound whiskey fits in.
"It will depend on what whiskey you're specifically referring to and is especially dependent on the alcohol content. Crown Royal (80 proof) freezes at approximately -13F. Something stronger like Wild Turkey, and God help you if that's your drink of choice-will freeze even lower than that, perhaps -30 or -40F."
Wild Turkey comes in 81 proof and 101. I assume you are talking about the 101. Turkey is very smooth.
