Wine country tours: New bottle cap thwarts wine counterfeiters" onclick="window.open(this.href);return false;

To combat this problem, Johnston and his colleagues in Argonne’s Vulnerability Assessment Team (VAT) have created a cap that winemakers can fit over the bottle’s cork. The cap contains a small circuit that completes when it is removed, triggering an electric pulse that creates electronic evidence someone has tampered with the bottle. “There’s no alarm that screams at you if the wine’s been opened,” Johnston said, “but there’s no way of getting rid of the evidence of tampering because basically, when tampering occurs, information is erased—a kind of anti-alarm.”
