Wow, that is a hard question. We know ethanol molecules numb the sense of smell, and they are by far the most abundant molecules in a sniff of spirit, well over 90%. In the lab we have measured significant differences in aroma detection after four good sniffs, and in competitions, nearly all judges experience difficulty by the third flight with tulip glasses (5 samples). In more than 100 competitions with the NEAT spirits glass, there has never been a reported instance of ethanol anesthesia, but it’s prevalent with tulip glasses. What spirits tasting glasses do you use? If you appreciate fine spirits, don’t be fooled by tulip glassware that hides aromas. NEAT, the ultimate spirits glass, should be your glass of choice.
