Discover the Fascinating World of Champagne Yeast: All You Need to Know About This Essential Ingredient in Sparkling Wine Making!

Champagne has always been synonymous with celebration, elegance, and luxury. It’s that bubbly drink that accompanies special events and adds a touch of sophistication to any gathering. Behind the glamour and glitter, lies a fascinating world of science and artistry that goes into the production of champagne. One of the essential ingredients that make champagne unique is the champagne yeast. In this article, we will explore everything you need to know about champagne yeast, from its role in champagne production to the different types of champagne yeast available.

What is Champagne Yeast?

First, let’s define what yeast is. Yeast is a single-celled fungus that feeds on sugars and produces alcohol and carbon dioxide as by-products. Yeast is an essential ingredient in wine making, as it transforms grape juice into wine by fermenting the sugars in the juice.

Champagne yeast is a specific type of yeast used to induce the secondary fermentation that creates the carbonation or bubbles in champagne. The Champagne yeast strain is a combination of the Saccharomyces cerevisiae and Saccharomyces bayanus species, which are carefully cultivated and selected for their unique traits that make them ideal for champagne making.

The Role of Champagne Yeast in Champagne Production

The first step in champagne production is to make the base wine. The grapes are harvested and pressed, and the juice is allowed to ferment with the help of regular wine yeast. The result is a still wine with a low alcohol content.

After the still wine is produced, it’s then bottled with sugar and champagne yeast added. The yeast consumes the added sugar and produces carbon dioxide as a by-product. Since the bottle is sealed, the carbon dioxide is trapped in the wine, creating the carbonation or bubbles that define champagne.

The yeast continues to interact with the wine for several months, during which it produces various compounds that contribute to the unique aroma and flavor profile of the wine. After the yeast has completed its work, it settles at the bottom of the bottle, and the wine is ready for bottling and aging.

Different Types of Champagne Yeast

There are several types of champagne yeast available, each with its unique characteristics and flavor profile. Here are some of the most common types:


EC-1118 is a popular champagne yeast strain used by many winemakers for its reliability and consistency. It’s known for its strong fermenting ability and high alcohol tolerance, making it a popular choice for making wines with a high alcohol content. EC-1118 is also known for its ability to preserve the wine’s varietal character while enhancing its fruity and floral flavors.

Prise de Mousse

Prise de Mousse is a yeast strain used primarily for its ability to produce a fine and persistent mousse or foam. It’s known for its ability to ferment at low temperatures, making it preferred for champagne production in colder regions. Prise de Mousse also produces a fruity and floral aroma profile, making it a popular choice for wines that require a delicate and elegant touch.


D47 is a yeast strain with a medium fermenting ability and alcohol tolerance. It’s popular for making wines with a balanced and complex flavor profile. D47 produces a spicy and fruity aroma profile, making it an ideal choice for wines that require a touch of warmth and richness.

How to Choose the Right Champagne Yeast

Choosing the right champagne yeast can make all the difference in the final product’s aroma and flavor profile. When choosing champagne yeast, consider the following factors:

Fermenting Ability

The fermenting ability of the yeast will determine the alcohol content and carbonation levels of the wine. Yeast strains with a higher fermenting ability and alcohol tolerance are ideal for making wines with a high alcohol content.

Flavor Profile

Different yeast strains produce different aroma and flavor profiles. Consider the flavor notes you want to achieve in your wine and choose a yeast strain that’s best suited for your desired taste.

Temperature Tolerance

Yeast strains differ in their ability to ferment at different temperatures. Choose a yeast strain that’s best suited for the temperature range you’ll be fermenting your wine.

Tips for Working with Champagne Yeast

Working with champagne yeast requires skill and precision. Here are some tips to help you achieve the best results:

Follow the instructions

Follow the instructions that come with the yeast package carefully. The instructions should specify the optimal temperature range, nutrient requirements, and timings.

Rehydrate the yeast

Rehydrate the yeast before adding it to the wine by mixing it with distilled water. The yeast should be given enough time to activate and multiply.

Monitor the fermentation

Monitor the fermentation process to ensure it’s proceeding correctly. Check the carbonation levels and alcohol content regularly to avoid any inconsistent results.


Champagne yeast is an essential ingredient in champagne production that plays a critical role in creating the wine’s unique aroma, flavor, and carbonation. Choosing the right champagne yeast strain can make a significant impact on the final product’s taste and aroma. Take the time to research and experiment with different yeast strains to create the perfect bottle of champagne.
