At Viña Don Melchor, we are committed to ensuring the authenticity of our wine. Starting with the 2022 vintage, we have introduced a security seal called Prooftag™ Bubble Seal® on the capsule of each bottle. This special seal is unique and cannot be duplicated. It is linked to a QR code and an alphanumeric code, which enables us to guarantee the quality of our products and prevent counterfeiting for the benefit of our customers. 

This seal features a Bubble Tag™ made of a translucent polymer, in which a random pattern of bubbles is self-generated by physical reaction. This unique constellation of bubbles corresponds to a specific identity, such as a fingerprint for each bottle. 

To verify your bottle’s authenticity, enter the alphanumeric code on the Bubble Tag™ on the seal.
