I don’t know where I read it but a great tip for helping you get a better nose of a scotch is to put your hand over the opening as you swirl it around. The act of swirling will lift up the flavors and by putting your hand over it, you trap those flavors within the confines of the glass. Then, when you’re ready, lift up your hand and stick your nose in.
When trying to get a good nose, get one nostril as close to the scotch as possible. At first I felt silly, does the extra few millimeters make a difference? It really dos. Give it a try and you’ll definitely get a stronger scent than if you were to stick both nostrils in evenly.
So, get one nostril in closer and put your hand over the glass to give you a stronger nose.
