7 best yeast for wine making

Yeast is a crucial component in the process of wine making.It is a type of microorganism that belongs to the fungi kingdom. Yeast plays a pivotal role in fermentation, which is the process by which sugars are converted into alcohol and carbon dioxide.

Here are some key points about yeast in wine making:

1. Types of Yeast: There are two main types of yeast used in wine making - wild (indigenous) yeast and cultured yeast. Wild yeast is naturally present in the environment and can be found on grape skins. Cultured yeast, on the other hand, is commercially produced and specifically selected for its fermentation properties.

2. Fermentation Process: Yeast consumes the sugars present in the grape juice and converts them into alcohol and carbon dioxide. This process can take several days to several weeks, depending on various factors including the type of yeast, temperature, and sugar content of the grapes.

3. Saccharomyces cerevisiae: This is the most common species of yeast used in wine making. It is a type of cultured yeast that is well-known for its ability to efficiently convert sugars into alcohol.

4. Temperature Control: The temperature at which fermentation occurs is crucial. Different strains of yeast have different temperature preferences. Controlling the temperature allows winemakers to influence the flavor profile of the final product.

5. Nutrient Requirements: Yeast requires certain nutrients to carry out fermentation effectively. These nutrients include nitrogen, vitamins, and minerals. In some cases, winemakers may need to add supplements to ensure that the yeast has everything it needs to complete the fermentation process.

6. Stress and Restarting Fermentation: Sometimes, yeast can become stressed during fermentation due to factors like high alcohol levels or temperature fluctuations. This can lead to a stuck fermentation, where the yeast stops working. In such cases, winemakers may need to take steps to restart the fermentation process.

7. Malolactic Fermentation: While yeast primarily converts sugars into alcohol, there is also a secondary fermentation process known as malolactic fermentation. In this process, bacteria convert malic acid into lactic acid, which can impart certain flavors and textures to the wine.

8. Yeast Strain Selection: The choice of yeast strain can greatly influence the final characteristics of the wine. Different strains may produce wines with varying aromas, flavors, and mouthfeel.

9. Yeast Autolysis: After fermentation, yeast cells can break down and release compounds into the wine. This process, known as autolysis, can contribute to the complexity and mouthfeel of the final wine.
