Authentic Findings: Chai Vault Certification

Authentic bottles in proper condition will be inputted into the Chai Vault. The Chai Vault is a groundbreaking, blockchain-supported system of tracking authenticity and provenance for the life of the bottle. The Certificate of Authenticity is visible online, in advance of purchase, ensuring top sales prices, retained value, and only authentic and sound purchases.

The Chai Vault anti-fraud solution for wine and spirits enables potential buyers to know a bottle is authentic and sound by viewing provable provenance online, before purchase, without being in physical proximity to the bottle. Sellers can expect top dollar for certified bottles. Consumers can focus on buying wines that are authentic rather than avoiding those that are not. Chai Vault proves bottle-level authenticity by layering multiple identifications on top of blockchain security.

The Chai Vault solution solves for authentication and registration of bottles at the time of production or in the secondary market when authenticated by a certified TCM Authenticator, or a licensed vendor with provable direct provenence.

Vendors then list certified bottles online with individual bottles’ hyperlinks so potential buyers and view the online certificate of Authenticity and Provenence which lists current conditions and an image of the actual bottle. Owner information can be encrypted for confidentiality, but the chain of selling vendors remains visible.

Example  – 1988 Domaine Leroy, Richebourg

Chai Vault certification is the only proof a bottle was authenticated by Chai Consulting or the team of affiliated, global TCM Certified Authenticators.

“Keen, experienced, and methodic is how I describe Maureen’s approach to wine authentication. Maureen Downey’s knowledge and experience have served as an invaluable tool in identifying questionable, highly collectible, often older, wine bottles I purchased.

Based on her findings, I was able to return bottles I had purchased or intended to purchase. I highly recommend her service as a wine professional!”.
