Authenticate My Wine

Authenticate My Wine

Whether you have concerns about a single bottle of wine, or an entire cellar, if you have made purchases recently or decades ago, we will help to determine the authenticity of your investment. Fine and rare wine markets are flooded with counterfeits and more bottles are being made and released, and even returned and continuously resold to new buyers by unscrupulous, uneducated or careless vendors.

Please allow us to help you protect your investment, defend purchases in advance of capital outlay, and insure only authentic bottles are enjoyed. and our parent company, Chai Consulting, have an amazing success rate of achieving remuneration for clients that have been sold counterfeit wines, without having to take the situations to court. The cost of inspection and reporting is on average only 2.9% of the value of the wine in question, which is far less than a drawn out legal battle, and without the publicity and stress.  

Statistics from 9 recent TCM Inspection Reports® covering 217 bottles:

  • Replacement value of the counterfeit bottles was US$8.7million.
  • Average bottle value in a report was US$40,074.
  • Lowest bottle value was US$1,800.
  • Average Per Bottle Report Cost = US$1,390.09.
  • Cost of Report per US$1k Bottle Value = $28.83.
  • Average Cost of reporting is 2.9% of the value of the counterfeit bottles.
  • The cost of a report is always less than lengthy litigation or the expense and public attention of a court case.

Do You Have Dozens, Hundreds or Thousands of Bottles Needing Inspection? Do You Have Old and Rare Bottles You Do Not Want to Ship?

With TCM Certified® Authenticators, and trainees, located all over the globe we are likely not far from your home cellar, hotel or restaurant wine cellar or professional wine storage facility. As we do with most of our clients who have had large numbers of bottles or whole collections to inspect, we are happy to travel to you and your wine.

For jobs with more than a few cases of wine, including whole collection inspections, we charge by the hour, or even by the day, which ends up being much more cost effective than a per bottle rate. Just as with the Cellar Management Services at Chai Consulting, Maureen Downey takes the details of each job into consideration and crafts job specific proposals for each large and unique authentication job, so that they are appropriate to the wines and the scope of work required.

For more information, please contact us.

“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!”

Inspection & Verbal Report

A TCM Verbal Opinion Report® is the clarity that every wine collector needs to ensure the wine they purchased, or are looking to purchase, is authentic.

A full TCM Authentication Inspection® is completed for each bottle. Over 90+ different points of information and characteristics are inspected using various types of magnification and lighting, and other proprietary methods to determine authenticity opinions. Bottles may be photographed for analysis and research purposes. Following inspection mental and physical notes and photographs are analyzed to determine opinions of authenticity of individual bottles. Once determined, findings are delivered, by individual bottle, to the Client in a TCM Verbal Opinion Report®. No written or paper report is delivered.

TCM Verbal Opinion Report® finds are confidential and are for personal edification only. Findings may not be used for marketing or sales purposes or to attain remuneration.

Inspection & Formal Report

Formal Reporting: Findings Delivered in One Of Two Ways


Chai Vault

Bottles deemed authentic, or consistent with known production standards following inspection and analysis, will be tagged and inputted into our groundbreaking, blockchain based Chai Vault by Everledger thereby certifying their authenticity as well as tracking and reporting provenance for their lifespan. The inspection data exists in the blockchain including notes and photographs, the bottles unique ID, or “thumbprint,” and an inspection certificate. The details of the authentication can remain private or made public by the owner to be used for marketing and sales purposes as long as the bottle matches the matrix stored as its unique ID in the blockchain and the RFID chip reads viable (unadulterated).

As the bottle changes hands, provenance information can be updated. Brokers, retailer and auction houses can link to the blockchain information in online catalogues and offerings to show the authentication information to potential buyers, for the life of the bottle, verifying the provenance and thus raising the value of the bottle.


TCM Inspection Reports®

Bottles deemed inauthentic or inconsistent with known production standards following inspection and analysis will be reported through detailed, draft, or court ready, written reports. Our extensive reports include photographs and descriptions of why the bottle is found counterfeit, or inconsistent with authentic production standards, and can include current market replacement valuation to compel vendors to settle quick and significant claims for bad purchases, without having to incur the costs of going to court.
