What will happens if you mix yeast sand apple juice and water?

If you mix yeast, apple juice, and water, you will likely create a simple fermentation process, resulting in the production of alcohol and carbon dioxide gas. Here's what will happen:

1. Activation of Yeast: The yeast cells, which are living microorganisms, will react to the presence of water and nutrients in the apple juice. They will become active and start to multiply by budding.

2. Sugar Breakdown: Yeast consumes the natural sugars present in apple juice, mainly fructose and glucose. Enzymes within the yeast break down these sugars into simpler molecules, producing ethanol (alcohol) and carbon dioxide (CO2) as byproducts.

3. Fermentation Process: The process described above is known as fermentation. During fermentation, the yeast will continue to convert the sugars in the apple juice into alcohol and release carbon dioxide.

4. Carbonation: The carbon dioxide gas produced during fermentation will gradually bubble up and cause the mixture to become fizzy or carbonated. The amount of carbonation depends on various factors, including the amount of yeast, temperature, and duration of fermentation.

5. Apple Wine or Apple Cider: As fermentation progresses, the apple juice will gradually transform into an alcoholic beverage called apple wine or apple cider. The sweetness of the final product will depend on the sugar content of the apple juice and the length of fermentation.

6. Sediment and Clarity: During fermentation, some yeast cells and sediment may settle at the bottom of the container. As the fermentation slows down, the beverage may become clearer, leaving the sediment behind.

7. Monitoring and Tasting: It's essential to monitor the fermentation process, especially if you aim to achieve a specific alcohol content or flavor profile. Tasting the mixture periodically can help you determine when the fermentation has reached the desired stage.

Remember, fermentation can be influenced by factors such as temperature, sugar content, yeast strain, and the presence of preservatives in the apple juice. If you intend to ferment apple juice as a hobby or to produce alcoholic beverages, it's best to research proper fermentation techniques, sanitization practices, and responsible consumption guidelines.
