Don’t warm the glass with your hands like you’re trying to hatch an egg. You’ll evaporate the good stuff. Just hold it by the stem or base. Your palm is not a furnace. Also, don’t sniff it for ten minutes straight—your nose will go numb and you’ll miss the party.
And please, avoid the “cognac and cigar” cliché unless you actually have a cigar. Pretending you’re a 1930s mobster with a lollipop stick is cute for exactly three seconds. After that, you’re just a person holding a stick.
