As I write this, I'm sipping three aged Scotches that have been fractionated into some nine glasses. It's mid-afternoon. Yes, I am at the Tales of the Cocktail convention in New Orleans again -- one part learning and one part drinking, served straight up. Some people prefer to vary the proportions slightly.
When you drink whisky, you're drinking the wood it was aged in. That's easy to understand in concept, but friend of PopSci Dave Arnold is here to spell it out for our taste buds: He has set up his laboratory evaporator and physically separated out the flavor components in a glass of Glenlivet so they can be sipped individually.
