Chai Vault partnered with Zachys on their nearly $3M Black Tie Collection auction,
with Chai Vault authenticity and provenance available online for each individual bottle.


Chai Vault is the first anti-fraud solution for wines and spirits that allows potential buyers to know a bottle is authentic and view provable provenance, before purchase, without physical proximity to the bottle. 

Consumers can now focus on buying bottles that are authentic rather than trying to avoid those that are not.


The Chai Method® - TCM®

TCM Certified Authenticators around the globe inspect and certify authentic bottles in the blockchain, creating a permanent, digital record.

Securing Authenticity

Detailed notes and photographs, the bottles’ unique ID, or "thumbprint" are inputted at time of production or following inspection by a TCM Certified Authenticator in the secondary market.


A bottle’s online Ledger of Authenticity & Provenance exists in the blockchain and can be kept private or made visible to the public for a licensed vendor to use for online marketing purposes.

Ownership Transfer

As a bottle changes hands, provenance information can be updated to include new ownership and storage information.

How does Chai Vault work?

Chai Vault is built on multiple layers of physical and virtual anti-fraud protection:

  • Multiple unique identifiers for each bottle
  • Immutable blockchain entries for every individual bottle
  • Detailed condition reports including unique individual bottle information
  • Record of provenance across multiple owners/transactions
  • Physical components designed to perform over decades of cellar storage
  • Owner control over whether bottles are visible to others
