Glencairn. Heat transfer isn’t an issue if you hold it by the base. Really worth it when you add a few drops of water and can really smell the whiskey open up.
I like them for bourbon, too, but I do have a shorter, a little more open version of the same glass from Kentucky Bourbon Trail, I think? Link below (they actually appear to be on quite the sale, I may grab some more). I prefer them for barrel proof stuff as it allows a little more of the nose to escape so I’m not runny-nosed trying to drink my bourbon.
