The Question: What process is used to turn grape juice into wine?
Fermentation is a chemical process that occurs when yeast consumes sugars and converts them to carbon dioxide and alcohol. Winemakers add yeast to grape juice and follow a rigorous process that can take up to a month to create the perfect blend. Fermentation isn’t only used in winemaking, however. It’s crucial to a variety of foods, including bread, yogurt, sauerkraut, and more.
The correct answer is Fermentation.
