How Is Sparkling Wine Made? Understanding The Traditional Method

Sparkling wine, with its delightful bubbles and celebratory flair, has captured the hearts of many around the world. Have you been wondering how this effervescent beverage is created? We’ll dive into the intricacies of sparkling wine production, focusing on the Traditional Method, also known as Methode Champenoise.

The Journey Begins: Primary Fermentation

The process of making sparkling wine starts much like that of still wine. It begins with the harvest of grapes, typically varieties such as chardonnay, pinot noir, and pinot blanc in the case of champagne. The grapes are pressed to extract the juice, which undergoes primary fermentation.

During primary fermentation, the natural sugars in the grape juice are converted into alcohol by yeast. The result is a still wine that forms the base for the sparkling wine. At this stage, winemakers often blend different base wines to achieve a desired flavour profile and complexity.

Creating The Sparkle: Secondary Fermentation

Once the base wine is ready, it’s time for the magic to happen: secondary fermentation. This is the process that gives sparkling wine its characteristic bubbles. Here’s how it works:

  • Tirage: The base wine is bottled with a mixture of sugar and yeast, known as the liqueur de tirage. This mixture is crucial as it initiates the second fermentation inside the bottle.
  • Bottling: The wine is then sealed with a crown cap (similar to a beer bottle cap) to trap the carbon dioxide produced during fermentation.
  • Secondary Fermentation: The bottles are stored horizontally in a cool, dark place. The yeast consumes the added sugar, resulting in a second fermentation. As a by-product, carbon dioxide is produced, which gets trapped in the sealed bottle, creating the sparkling bubbles we all love.
  • Aging On Lees: After secondary fermentation, the wine is left to age on its lees (the dead yeast cells) for several months to several years. This ageing process adds complexity and richness to the wine, contributing flavours such as toasty, nutty, and creamy notes. The duration of this ageing can significantly impact the wine’s character.

Riddling: Preparing For Disgorgement

After ageing, the wine is ready for the next critical step: riddling. This is the process of gradually tilting and rotating the bottles to encourage the sediment (lees) to settle near the neck of the bottle.

  • Riddling Method: Traditionally, this was done by hand in a process called pupitres, where bottles were placed in wooden racks at an angle and turned regularly. Today, many producers use gyropalettes - machines that automate this process, making it more efficient.

Disgorgement: Removing The Sediment

Once the sediment has settled, it’s time for disgorgement. This step involves removing the sediment from the bottle to ensure a clear sparkling wine.

  • Freezing The Neck: The neck of the bottle is immersed in a freezing solution, creating an ice plug that traps the sediment.
  • Opening the Bottle: The crown cap is removed, and the pressure inside the bottle forces the ice plug - and the sediment - out of the bottle.

Dosage: Sweetening The Deal

After disgorgement, the wine may be adjusted with a small amount of dosage, a mixture of sugar and wine, to achieve the desired sweetness level. This step is crucial, as it determines the final style of the sparkling wine. The levels of sweetness can range from:

  • Brut Nature: No added sugar
  • Extra Brut: Very little added sugar
  • Brut: The most common style with some sugar
  • Demi-Sec: Noticeably sweet

Corking And Labelling

After the dosage is added, the wine is corked with a traditional cork and secured with a wire cage (muselet) to hold it in place. Finally, the bottles are labelled and prepared for distribution.

Enjoying Sparkling Wine

Now that you know the meticulous process behind the production of sparkling wine using the Traditional Method, you can appreciate each sip even more. Whether you’re enjoying a classic champagne, a delightful cava, or a refreshing prosecco, you’re indulging in a product of craftsmanship and tradition.

Conclusion

The journey of sparkling wine from grape to glass is a fascinating process filled with skill and artistry. Understanding how sparkling wine is made, especially through the Traditional Method, enhances our appreciation for this effervescent drink.

Next time you pop open a bottle, remember the intricate journey it undertook to bring those delightful bubbles to your glass. Cheers!
