Exploring the Most Common Types of Yeasts Used in Wine Production
Wine production is an art that relies on the delicate interplay between various factors, including grape variety, fermentation process, and yeast selection. Yeast plays a crucial role in wine production, as it converts sugars into alcohol and contributes to the wine's flavor profile. Among the multitude of yeasts available for winemaking, several stand out as common choices due to their unique characteristics and suitability for different styles of wine.
Saccharomyces cerevisiae: Known as "wine yeast," Saccharomyces cerevisiae is one of the most prevalent types of yeast used in winemaking. This species is valued for its ability to efficiently convert sugar into alcohol and carbon dioxide during fermentation. Additionally, Saccharomyces cerevisiae contributes desirable aromatic compounds and flavors to the wine, enhancing its complexity.
Saccharomyces Bayanus: Another commonly used yeast strain in winemaking is Saccharomyces Bayanus. This type of yeast exhibits a high tolerance to alcohol content, making it suitable for fermenting wines with higher alcohol levels such as fortified wines or those made from grapes with elevated sugar content.
Lalvin EC-1118: Lalvin EC-1118 is a specific strain within the Saccharomyces cerevisiae species known for its strong fermentation characteristics and ability to produce clean-tasting wines with neutral aromas. Winemakers often choose this yeast when they want minimal influence from the yeast on the final flavor profile, allowing other aspects such as grape varietals or terroir to shine through.
Innoferm Sensy: Is a newer addition that has gained popularity among winemakers due to its low production of sulfur compounds during fermentation which minimizes off-flavors associated with sulfides while preserving desirable fruity aromas in white wines.
The choice of yeast can significantly impact a wine's sensory qualities such as aroma, taste, mouthfeel, and overall character. When selecting a particular type of yeast for wine production, winemakers consider various factors such as:
1. Grape Variety: Different grape varieties possess distinct attributes that can interact differently with specific yeasts.
2. Fermentation Conditions: Temperature control during fermentation can influence which yeasts thrive best under certain conditions.
