1
In a container, mix 2.5 cups of water at 21 degrees with two cups of flour. If there are lumps left, don't worry, they will dissolve later.
- Wheat flour: 5 glass
- Water: 5.5 glasss
2
Place the grapes without stems in a doubled piece of cheesecloth, tie the corners to form a pouch. Gently crush the grapes with a rolling pin and immerse them in the flour mixture. Seal the container tightly with a lid or plastic wrap. Leave at room temperature for 6 days, stirring daily.
- Red grapes: 250 g
3
The bag with grapes will gradually rise, and the mixture will separate. Its color will become quite strange, and it will have a slight fruity smell. This is normal. On the sixth day, the grapes will float, the mixture will turn yellow, and it will taste pleasantly sour: this means fermentation is complete. Now the starter needs to get nutrients and grow.

Take the bag of grapes and squeeze all the juice into the starter, then discard the grapes. Mix the starter well and pour it into a clean container.
- Red grapes: 250 g

Mix one cup of flour and water into the starter, leave the container uncovered for 3-4 hours until it starts to bubble. Then cover it and put it in the refrigerator for a day.
- Wheat flour: 5 glass
- Water: 5.5 glasss

The next day, mix in another cup of flour and water, leave at room temperature until bubbles appear, then put it in the fridge. Repeat this procedure the next day, and after proofing in the fridge, the starter will be ready to use.
