How to Choose the Best Champagne Yeast in Australia: A Guide for Wine Enthusiasts

Champagne yeast is a crucial element in creating fine sparkling wines. It is the yeast’s ability to withstand high alcohol levels and produce carbon dioxide that gives the wine its signature bubbles. As a wine enthusiast, you know that the choice of yeast can impact the taste, aroma, and overall quality of the wine. Choosing the right champagne yeast in Australia can make or break your wine-making process. In this guide, we will explore everything you need to know about champagne yeast in Australia.

What is Champagne Yeast?

Champagne yeast is a type of yeast specifically designed for the production of sparkling wines like Champagne. It is known for its ability to ferment wine to high alcohol levels and withstand the pressure created by the carbon dioxide produced during fermentation. Champagne yeast belongs to the Saccharomyces cerevisiae family and comes in various types.

Types of Champagne Yeast

Champagne yeast types vary in their ability to utilize specific types of sugars and their temperature range for fermentation. Here are some of the most common champagne yeast types in Australia:

EC-1118 Yeast

The EC-1118 yeast strain is a popular choice among winemakers due to its versatility. It can ferment at temperatures as low as 7°C and as high as 35°C, making it suitable for a wide range of wine styles. This yeast is particularly good at fermenting fructose, which makes it suitable for adding fruit flavors to wines.

DV-10 Yeast

DV-10 is another popular yeast strain that is particularly good at fermenting at lower temperatures. It is perfect for creating wines with delicate fruit flavors while still maintaining a high alcohol content.

Uvaferm 43 Yeast

Uvaferm 43 is a champagne yeast strain that is excellent for creating fruity wines. It is particularly adept at fermenting glucose, making it perfect for fermenting grape juice.

Factors to Consider when Choosing Champagne Yeast in Australia

Choosing the right champagne yeast in Australia can be a daunting task, especially for beginners. Here are some of the factors you need to consider:

Wine Style

Different wine styles require different types of yeast. For instance, if you’re making a fruity wine, you’ll need a yeast strain that can ferment fructose efficiently. On the other hand, if you’re making a traditional Champagne-style wine, you’ll need a yeast strain that can withstand high alcohol levels and produce enough carbon dioxide to create the signature bubbles.

Fermentation Temperature

Different yeast strains have different temperature ranges for fermentation. It would be best to choose a yeast strain that matches the fermentation temperature requirement for your wine. Fermenting outside the recommended temperature range can lead to unwanted flavors and aromas in your wine.

Alcohol Tolerance

The alcohol tolerance of the yeast strain determines the maximum alcohol level your wine can achieve. This is particularly important if you’re making a high alcohol wine like Port. Choosing a yeast strain with a high alcohol tolerance will ensure that your wine ferments to completion and achieves the desired alcohol level.

Nutrient Requirements

Yeast requires nutrients to thrive during fermentation. Different yeast strains require different nutrient levels. Some yeast strains may require additional nutrients like nitrogen, which can affect the flavor and aroma of your wine.

pH Level

Yeast fermentation is also affected by the pH level of the wine. Different yeast strains have different pH level requirements for optimal fermentation. It’s essential to choose a yeast strain that can ferment at the pH level of your wine.

Availability

Not all types of champagne yeast are readily available in all parts of Australia. Consider checking with local wine brewing stores or online suppliers to find the right yeast strain for your wine.
