No way. I have been enjoying a dram or three even on some of the hottest days. My preference has been the 9yr old Springbank from Murray McDavid reviewed months ago. I also have found that a rare 1979 HP has been able to really hit the spot.
I have heard that there is a Whisky made to be frozen. Looking for some if anyone is passing thru a UK airport. It is the Famouse Grouse's Snow Grouse. Reviews are not great, but sounds interesting.
