Since 2013 an authentication seal is affixed to all bottles leaving the winery of Masseto. This seal includes information pertaining to the specific bottle in question, which is registered in a database accessible to consumers.

Guaranteed origin and integrity
This seal, developed by Prooftag™, offers dual protection.
– A tamperproof seal on the capsule confirms the origin and integrity of the bottle, and clearly shows any attempt to alter it.
– The seal has a Bubble Tag™ consisting of a translucent polymer in which a random configuration of bubbles is self-generated by physical reaction. This unique constellation of bubbles corresponds to a unique identifier, just like a fingerprint, for each bottle. The Bubble Tag™ is associated with an alphanumeric code and a QR code.

Identify and authenticate your bottles
You can authenticate your bottle whenever you wish by comparing the Bubble Tag™ on the seal with that on the Masseto website.
Enter the bottle’s alphanumeric code or flash your bottle’s QR-Code with your smartphone using the I-Proof or Mobiltag application.
