Glassware Rim Height from Liquid

If you have a tulip glass, pour 1/2 oz. whiskey and sniff. Not much besides ethanol on your nose if the distance to the liquid is greater than 3”. Add in small increments and sniff each time. As the spirit level approaches your nose, you pick up enough aromas to detect more character. Why? Different aromas = different molecular masses, gravity keeps larger mass aromas closer to the liquid surface. Ethanol is the lightest compound and moves quicker away from the surface due to vapor pressure. Tulip glasses including the Glencairn nosing glass and Norlan glass are too tall. The best spirits glass gets your nose close. Many aromas may never reach the top for detection. Short is good for character aromas, tall for strong ethanol aroma.
