Cracking the Code: Understanding Champagne Bottle Markings
Those letters and numbers on your Champagne bottle aren’t just decorative. They serve a vital purpose in the Champagne region and the broader industry. These codes also help identify how different Champagne houses and growers produce their wines, highlighting the unique production processes and styles each producer brings to the region of Champagne.
These markings are important to the production and distribution of this sparkling wine. They help track bottles, manage inventory, and ensure quality control.
However, decoding these markings can be challenging for consumers unfamiliar with the system.
Producer Identification
The most prominent code is the producer code, which identifies the Champagne producer. For example, NM 74 designates Mumm, a large Champagne producer in the Champagne region. Another example is Veuve Clicquot, a renowned Champagne house, which is also identified by its own NM producer code.
There are seven different categories of Champagne producers:
NM - Négociant-Manipulant – A company or an individual that trades exclusively as a Champagne House. They depend on grape growers for the bulk of their Champagne production.
RM – Récoltant-Manipulant – Also known as Grower Champagne. These organisations make and market their own Champagne, which is made exclusively from the grapes that they grow; 5% of purchased grapes are permitted in the blend.
RC – Récoltant-Coopérateur – Individuals who market wine that has been produced through a Champagne cooperative but is sold under their label.
SR – Sociéte de Récoltants – A group of growers who work together but are not a cooperative. They are permitted to use cooperative facilities if needed.
CM – Coopérative de Manipulation – A co-op owned by a group of grape growers who make Champagne by combining their grape harvests together using either its own label or that of its members, about fifty percent market their own products.
MA – Marque Auxilaire, Marque d’Acheteur or Marque Autorisée – A third party (not a producer) who owns a Champagne brand not related to the actual producer, such as a restaurant or wine merchant. MA Champagne may be sourced from an NM, RM, or CM producer.
ND – Négociant-Distributeur – Company or individual who buys finished bottles of Champagne and labels them with their name at their premises, then sells them.
Disgorgement Date
One key piece of information is the disgorgement date. Disgorgement, part of the méthode champenoise, removes sediment after secondary fermentation.
Disgorgement dates can be difficult to find, as they are not always clearly marked on the bottle. Many producers hide this information within lot codes, bottle markings, or on neck tags, making it a challenge for consumers to find the disgorgement dates without expert knowledge or guidance.
While some labels and apps make this easy, sometimes you’ll need code-cracking. Thankfully, Champagne writer Tyson Stelzer created a guide to navigate bottle markings.
In addition to checking disgorgement dates, it's also important to note the ideal serving temperature for Champagne, which can be measured with a laser thermometer for the best tasting experience.
Other Markings
Additional codes refer to bottling line, date, or other producer tracking info. While NM identifies big Champagne houses, grower Champagne bottles carry specific vineyard or village designations instead of producer codes.
These serve as a nod to the place of origin and personality of each wine production site.
Do You Know the Secret Code on Champagne Bottles? A Closer Look
Let’s explore what each code piece reveals, making you a Champagne detective. Understanding these markings enhances your bubbly pursuit. Embarking on the process of decoding Champagne codes is a quest for deeper knowledge and appreciation of each bottle.
Deciphering the Disgorgement Date
The disgorgement date is informative, but often hidden. Consumers often need to read post codes or lot numbers on the bottle, neck, or cork to determine disgorgement dates, as this information is rarely clearly labeled. This is where your detective skills come in.
| Producer | Code System |
|---|---|
| Agrapart | Year of disgorgement (number) and month (letter - A for January, B for February, etc.) on the cork. |
| Bollinger | First two digits of the labeling code (neck): Next three digits: day of the Cork letter: month of disgorgement, number: year. |
| Krug | First three digits of the ID code above the barcode: Trimester (first digit) and year (second and third digits) of disgorgement. Krug ID provides further details via their app and website. |
These are just a few examples; refer to Stelzer’s guide for producer-specific practices. Understanding how to read these post codes and lot numbers can help you avoid buying bottles that have been sitting on shelves for too long.
Identifying Growers’ Champagnes
“RM” (récoltant-manipulant) signifies a grower’s Champagne. These producers, often smaller brands, grow their grand cru
A grower’s Champagne is produced by the same people who grow the grapes, emphasizing personal care from base vintage selection to the final winemaking process. The blend of grapes in grower Champagnes reflects the unique characteristics of the vineyard.
Look for these markings if you seek wines produced at a small winemaking facility that buys grapes or operates its vineyard.
Beyond the Codes: Other Quality Indicators
Champagne codes are important, but not the only quality clues. Other factors reveal care during production. The winemaking process also contributes significantly.
Look at distribution channels. These can offer information on storage and handling. Where your bottle has traveled is part of its story.
Buying from reputable sources like these Champagne experts reassures quality and authenticity. By understanding label codes, you can choose and buy Champagne more confidently, ensuring you select bottles with the qualities you want. Also, consider using premium glasses like Riedel Glassware. The right glassware lets the Champagne flavors flourish. Learn more with this detailed champagne guide.
Here is a list of tips to help you choose quality Champagne:
- Check for clear labeling of vintage, disgorgement, or bottling dates.

In wine terms, “age” refers to how long ... More.
- Buy from trusted retailers or directly from producers.
- Choose bottles stored properly and away from direct sunlight.
