Champagne bottle codes

Information behind closed doors

Champagne is the most code-bodyguarded wine region on earth and one of its biggest secrets is beginning to get out.
The age of a bottle of non-vintage champagne has long been a mystery. It’s been impossible to distinguish from the label a fresh, young bottle from a stale one, to track a collection in the cellar, to identify one batch or bottling from another and, most significantly, to choose a blend based on a great vintage rather than one marked by a lesser season.

This information is getting out!

A new day is dawning in the convoluted world of champagne communication and many smaller producers and even some larger houses are now beginning to disclose the age of their non-vintage bottlings.
The two most useful time stamps for a non-vintage cuvée are the date of bottling (almost always the year following the base vintage) and the date of disgorgement, when the bottle leaves the cellar to receive its cork (usually between a few months and a year before it is shipped).
There are rumours that the CIVC, guardian of Champagne’s regulatory requirements, is contemplating mandating disgorgement dates on back labels. Until this happens, decoding this information is not always straightforward, since there is no standard for declaring dates.

How to read the code

Those houses that do kindly volunteer this information use all manner of systems, hidden in difficult to read bottling codes etched into the glass of the bottle, printed on the neck label or the back label, printed in plain English or French on back labels, coded on front labels or corks, or accessed via QR codes, ID codes, web sites or dedicated apps.

Your code breaker’s guide

In The Champagne Guide 2016-2017, I explain how to crack the code for every grower and house who have volunteered their system. The following list offers a complete summary so you can quickly decode the next bottle you buy.
More champagne houses and growers are adding this information to their bottles, so if you spot one not yet in my list, please email the details to and I’ll add it.
In the meantime, this code breaker’s guide will equip you with everything you need to find the freshest bottles on the shelves.

Disgorgement dates aren’t printed on back labels, but they’re easy to decode from the cork. The number is the year of disgorgement, and the letter is the month (A for January, B for February, and so on).

Disgorgement dates are not stamped on non-vintage bottles (they are on the vintage wines). Labelling occurs shortly after disgorgement, so the labelling date provides a good indication. The first two digits of the labelling code on the neck of Special Cuvée and Rosé are the year and the next three digits are the number of the day of that year, so L1405002 means the 50th day of 2014. The letter on the cork is the month of disgorgement and the number is the year, so 4A is January 2014.

For champagnes disgorged to order, back labels are impressively informative, disclosing disgorgement date, blend and dosage.

Using this code, and the Krug app reveal the season and year in which the bottle was shipped, the number of years over which it has aged, the blend and the vintage story for vintage wines, and the number of wines and each of the vintages in non-vintage blends. This code also reveals the disgorgement date on the spot, since the first three digits are the trimester (first digit) and year (second and third digits) of disgorgement.
