What kind of whiskey is served cold? I really like my alcoholic beverages cold. But I do know most whiskeys should be served in room temperature. 

Although adding ice is an option, I do not prefer this method because when ice melts, the whiskey is mixed with water.
Using whiskey stones is good for drinking at home, but I cannot carry my stones around (for instance in a bar).

So, what type of whiskey is served chilly so I can order that one when I go to a bar?
One whiskey that I know of is the Snow Grouse it is a blended grain whiskey that as by the name is supposed to be drank cold.
 Some would even say that this whiskey is better straight from the freezer
