In our last discussion Behind Champagne Part 3 : Reveal The Art of Sugaring, we explored how to precisely calculate the amount of carbon dioxide produced during secondary fermentation, highlighting the key role of the sugar solution known as ‘Liqueur de tirage.’ This addition not only fuels the effervescence but also plays a crucial part in developing the rich flavor profile of Champagne.
Have you ever wondered what gives this traditional French sparkling wine its distinctive toasty, nuttyđ„, creamy or more specifically baking bread or briocheđaroma? What sets it apart from other sparkling ones, such as Prosecco? Let’s dive deeper into the enchanting process behind the creation of its unique brioche aroma. This topic, while rich with complex scientific terms, offers fascinating insights into the chemical reactions that produce such delightful aromas. Understanding these reactions will not only deepen your appreciation of this sparkling wine but also enhance the joy of each sip. Are you ready to uncover the secrets of its irresistible scent?

1. Pre-DĂ©gorgement: Priming the Brioche Aromas of Champagne
The aging of champagne is categorized into two stages: pre-disgorgement and post-disgorgement. During the pre-disgorgement phase, the yeast undergoes autolysis, actively breaking down inside the bottle. This phase begins with the yeast absorbing oxygen while the crown cap ensures no additional oxygen enters, creating a highly reductive environment.
As a result, the yeast starts to break down its own cell walls. The low pH and cool storage temperature of the wine mean that this autolysis process advances very slowly, typically beginning 2 to 4 months after secondary fermentation is completed. Post-disgorgement starts once the dead yeast cells are removed, and the champagne receives its final touches.
Throughout this phase, the yeast breaks down its components, releasing substances such as amino acids and proteins into the wine. Key elements of the cell walls, like glucans and mannoproteins, start to disintegrate.
Mannoproteins contribute to a richer mouthfeel, while glucans help stabilize the bubbles in champagne. While it’s a common belief that the yeasty flavors of champagne develop during this stage, the signature ‘brioche aroma’ isn’t quite formed yet. Instead, the wine is stored in such a reductive environment that it maintains an exceptional freshness, reminiscent of a top actress who seems untouched by time.
While the Maillard reaction initiates the development of complex flavors soon after disgorgement, the full depth and richness of its iconic aroma profile continue to evolve during prolonged aging on the lees.
2. Post DĂ©gorgement: Mastering Complex Brioche Aroma
2-1.The Maillard Reaction – Building Complex Flavors
This sparkling wine can spend anywhere from one year to over a decade in contact with lees before it undergoes disgorgement. This process involves expelling the dead yeast and then adding a dosage to replace the lost wine, followed by sealing the bottle with a cork and wire.
This transition marks the beginning of the post-disgorgement period. It’s during this phase that the Maillard reaction takes place. Commonly mentioned in cooking such as meat steakes, this reaction involves amino acids from the yeast remains and sugars from the dosage combining, which accelerates the formation of complex flavors and aromas in the champagne.
The Maillard reaction, which occurs during the post-disgorgement period after the champagne has been corked and allowed to age further, is pivotal in developing rich flavors such as toast, whisky, smoke, baking bread, brioche, nuts, and caramel. These complex flavors contribute to the characteristic âbaking bread, brioche aromaâ that justifies the premium price of it. For this reason, many champagne houses opt to release their wines only after this additional aging phase.
The Maillard reaction requires sugars, so the wines that have little or no added sugar, like Brut Nature or Extra Brut, tend to exhibit fewer of these toasty characteristics. On the other hand, this bubbly that have undergone oak fermentation and retained some sugars from the oak are more likely to enhance the effects of the Maillard reaction. Additionally, the longer the wine remains in contact with the lees, the more pronounced the baking bread aroma becomes, due to the increased production of amino acids from the yeast’s autolytic process.
2-2: Prolonged Aging – Enhancing Aroma and Bouquet
In Champagne, regulations stipulate that non-vintage champagnes must age on the lees for at least 12 months, while vintage champagnes require a minimum of 36 months. However, many producers exceed these minimums, seeking to enhance flavor complexity.
Studies show that these traditional sparkling wines generally need around 18 months on the lees for bread and biscuit aromas to become clearly noticeable. This explains why basic-level Cava from Spain and entry-level American sparkling wines, which employ traditional champagne methods, may only exhibit subtle bread-like aromas.
Wines with prolonged lees contact and late disgorgement tend to age more rapidly once released. Accustomed to a reductive environment, they oxidize and mature more swiftly when exposed to oxygen after disgorgement. While some producers and experts recommend that RD (Recently Disgorged) champagnes not be stored for extended periods, opinions on this matter vary.
By considering the inherent quality of the champagne, the duration of lees contact, and the timing of dégorgement, you can anticipate how the champagne will evolve. As you choose between its vibrancy and its rich, bready aromas, remember that each bottle is a testament to the meticulous care and expert craftsmanship that define the region. This choice not only reflects personal taste but also the profound legacy of its traditiongal winemaking.
Maybe next time you uncork a bottle, think about these elementsâeach sip represents a chapter in the storied tradition. Whether you lean towards the lively zest of a young vintage or the complex notes of a well-aged cuvĂ©e, discovering your favorite style is part of the joy of this amazing iconic effervescent.
