- Crush the grapes: This can be done by hand or with a mechanical crusher.
- Press the grapes: This separates the juice from the skins and seeds.
- Add yeast: Yeast is added to the juice to begin the fermentation process.
- Ferment: The mixture is then left to ferment for several days or weeks, during which time the yeast consumes the sugars in the juice and converts them into alcohol.
- Press again: After fermentation is complete, the wine is pressed again to separate the solids from the liquid.
- Age: The wine is then aged in barrels or bottles for several months or years before it is ready to drink.
There are many factors that can affect the fermentation process, such as the type of grapes used, the temperature and humidity of the environment, and the type of yeast used. It is important to carefully control these variables to produce high-quality wine.
