Guardian of the bottle and the precious bubbly inside, the cork serves an essential role in the preservation of Champagne. Immediately following disgorgement, this porous, mushroom-shaped stopper is squeezed into the glass neck of the bottle, blocking the pressure from escaping and the oxygen from flooding in. Over the years, it has evolved and adapted to this very special role. Learn more about the history, design and creative ways to reuse a Champagne cork!
Although the inventor of cork-based wine stoppers remains a mystery, the latter were born sometime in the mid-17th century. Before this time, winemakers would use a broquelet (basically a wooden toggle wrapped in hemp and then soaked in tallow) to plug their bottles. This technique was far from full-proof, however, and often led to leaking bottles.
Local legend in the Champagne region attributes their invention to the Benedictine monk Dom Pierre Perignon, after whom Dom Perignon Champagne was named and who is also said to have invented the traditional method of sparkling wine production, involving fermentation taking place in the bottle of sparkling wine. This legend has, nevertheless, been debunked.
By the 18th century, the use of corks had become well-documented, especially after King Louis XV issued an edict on the bottling of Champagne. Back then, winery workers would squeeze the corks into Champagne bottles by hand, tying them with twine to keep them in place. This led to frequent accidents, the pop of a Champagne cork potentially leading to the loss of an eye. By the 19th century, winery workers would wear masks made of wire and gauze to protect against the Champagne cork.
It was not until the 20th century that the process of inserting corks into sparkling wine bottles was mechanized. Today, corking Champagne is a perfectly safe step in its production process.
Champagne and sparkling wine corks typically have a diameter of 1.2 inches and are 2 inches long. Before pushing the cork into the bottle neck, the corks are compressed to around 60-70% of their original diameter. In fact, these corks are originally perfectly cylindrical. The compression of the bottom segment before insertion gives the Champagne cork its iconic mushroom shape.
Most sparkling wine and Champagne corks have 3 different sections, named agglomerated corks. The bottom of the stopper features two natural cork disks stacked against each other. The bottom disk, which stays in contact with the wine, is referred to as the mirroir (mirror). The top section is made of reconstituted granules of cork held together by glue. The microscopic pores in the cork allow a very small amount of oxygen to filter in, leading to micro-oxygenation, crucial in the aging process.
All natural Champagne corks must bear the name of the Champagne appellation, as well as the vintage for vintage style champagne.
When it comes to Champagne, the pressure created by secondary fermentation in the bottle of wine pushes out the cork once it is ready to be opened, contributing to the famous “cork pop” we know and love, especially at a celebration like a wedding or birthday party.

Immediately after a wine is disgorged to remove the dead yeast cells and dosed with a mixture of wine and sugar, it is sent for corking. The sparkling wine cork is first compressed into the mushroom shape and then squeezed into the neck of the wine bottle by a machine specially designed for this purpose. After insertion into the sparkling wine or Champagne bottle, the cork is held in place by a wire cage, also known as a muselet.
Following the corking process, the bottles with champagne cork already in them are vigorously shaken in a process known as poignettage. This allows the liqueur de dosage to marry with the wine. The bottles are then set aside for a few months or even years of aging in the cellars of the Champagne house before commercial release.

According to Bollinger Champagne House, there is a popular tradition in Champagne, which involves creating a talisman out of a Champagne cork. After opening a bottle of Champagne, the cork is slit with a knife and a coin is slotted into it, transforming it into a talisman that is meant to bring prosperity and lucky to the person in whose honor the bottle has been opened.
The tradition dates back centuries and was inspired by sailors, who would slip their gold louis into their nets in order to ensure a lucky catch. The act is still quite common in the UK, where the person serving the Champagne will traditionally offer this token to the person of honor. As the cork expands and tights over the coin with time, it eventually becomes impossible to remove. This is meant to symbolize the eternal nature of a special celebration, locked in a moment in time.
