Maureen Downey & Everledger Join Forces to Combat Counterfeit Wine with the Introduction of the Chai Wine Vault

LONDON, November 18, 2016 - Set to transform provenance tracking in the wine industry, authenticator Maureen Downey and emerging technology company Everledger are today introducing the Chai Wine Vault.

A first of its kind solution in industry, the Chai Wine Vault ensures the value and protection of fine wine investments. The vault secures fine wine’s provenance and authenticity in an immutable digital ledger, powered by blockchain technology. A demonstration and further explanation of this complete solution to protect the provenance of fine and rare wine will take place on November 25th, at 67 Pall Mall, London.

“We’re starting to see the industry waking up to the impact of counterfeits in market but to date there hasn’t been a solution that could adequately verify a wine’s provenance,” says Maureen Downey, owner and founder of Chai Consulting LLC and world renowned authenticator of fine wine. “Wine certified on the Chai Wine Vault has a guarantee of authenticity, ensures buyer confidence, and protects the future value of wine assets for centuries to come.”

To authenticate a bottle, The Chai Method (TCM) collects 90+ data points, high-resolution photography and records of a bottle’s ownership and storage. Everledger uses this data to produce a unique, digital thumbprint of the bottle that is written permanently into the blockchain.

This digital proof now travels with the wine as it moves between the different stakeholders in the wine supply chain, with ownership and storage records updated as the bottle changes hands. Licensed retailers, warehouses, auction houses and other sale platforms can link to the bottle’s digital identity to verify provenance resulting in an increase of the asset’s value for years to come.

Building on blockchain’s core characteristics -  immutability, security, speed and scalability - Everledger has spent the last year creating a digital, global ledger for the diamonds industry. The company’s core function is the underlying technology powering the Chai Wine Vault, with the aim of preserving the provenance of fine wine.

“Blockchain gives us the ability to preserve the origin and identity of an asset in ways we were never able to before,” says Leanne Kemp, CEO and Founder of Everledger. “Similar to the diamond supply chain, the wine industry has been fraught with the movement of counterfeits and the threat of fraudulent bottles being traded through trusted sources. We have the potential to apply this technology to solve these problems and ultimately add a layer of transparency and trust to the goods we trade and sell globally.”

Accounting for an estimated 20% of international wine sales, counterfeit bottles have increasingly become a problem in the fine wine industry affecting the chain of provenance connected to the wine’s journey from grape to glass. The recent arrest of wine fraudster Rudy Kurniawan, who sold over $150 billion in counterfeit bottles, is only further proof of the unknown number of counterfeit bottles still circulating in market.

Until today only the formal reporting of an authenticator could prove a bottle of wine was counterfeit. Certifying a bottle as authentic was impossible given the risk of document tampering and the inability for the certificate to stay connected with the wine as it changes ownership and location.

Providing a single version of the truth and transparency for industry at every stage of a bottle’s lifetime journey, The Chai Wine Vault is the solution to secure the investment and value of wine for years to come.
