20. Drinking wine
There’s a very specific reason why glasses of wine are shaped as they are, and it’s not purely for aesthetic reasons. Not many people know this, but most of us are holding our wine glasses wrong. While these glasses are meant to be held by the long stem, between our index finger and thumb, most of us hold them by the cup.
This might seem like the intuitive way to hold any glass, but that is not the case. Holding glasses of wine by the cup, rather than the stem, makes our drink warmer, which changes the flavor of the drink. Next time you enjoy a glass of wine with a group of friends, share this tip with them.
