How can I prevent wine cork crumbles from falling into my wine glass when opening a bottle?

To prevent wine cork crumbles from falling into your wine glass when opening a bottle, use a corkscrew with a sharp, clean screw and insert it carefully into the cork. Twist the corkscrew slowly and steadily, keeping it straight to avoid breaking the cork. Once the cork is partially out, gently pull it out with your hand to prevent any crumbles from falling into the wine.
