Chai Wine Vault

a project that verifies authenticity of wines and reduce wine counterfeiting, especially of wine purchased as an investment asset

This project is marked as inactive in our database. Information may be outdated.

Chai Wine Vault was launched in 2016 by Leanne Kemp’s London-based blockchain company Everledger, an alumnus of the TechStars Barclays accelerator, and counterfeit prevention firm Winefraud.com. In 2013, French paper Sud Ouest reported that 20% of international wine sales are counterfeit. One estimate puts the value of counterfeit wine in circulation at over US$1 billion. Chai verifies authenticity of wines and reduce wine counterfeiting, especially of wine purchased as an investment asset. Photographs, records of ownership, and more than 90 data points are collected to create a digital profile for each bottle of wine, and bottles are equipped with tamper-proof technology created by British firm Bowater. Records are then updated each time the wine changes ownership so that future investors know the provenance of the wine.
