One of the most annoying things when drinking an elegant glass of wine in the evening is that smear of red that just won’t come off. Chapstick does it too, fellas; even if it’s colorless, that smudge looks messy. Aside from wearing lip stain or long-last lipstick (which can come off in flakes on the glass, anyway, and then is just long-lasting on your wineglass), there is a simple and effective way to avoid The Smudge: lick the glass edge first. This works because oil and water don’t mix. You just need to find a discreet moment to lick it, and remember that once it dries, you need to do that again.
