3. Transfer the cooked rice to a large bowl and let it cool to room temperature.
4. In a separate bowl, mix the nuruk and sugar with water to create a paste.
5. Add the rice to the nuruk paste and mix well to combine.
6. Transfer the mixture to a clean glass jar and cover it with a clean cloth.
7. Let the mixture ferment in a dark, cool place for at least 1 week, stirring occasionally.
8. After 1 week, strain the mixture through a cheesecloth to remove any solids.
9. Transfer the liquid to a clean bottle and store it in the refrigerator.

Beer is typically made using the following ingredients and steps:

Ingredients:
- Water
- Barley malt
- Hops
- Yeast

Steps:
1. Malting: Barley grains are soaked in water and allowed to germinate, then dried in a kiln to produce malted barley.
2. Mashing: The malted barley is crushed and mixed with hot water to create a mash. This process extracts sugars from the barley.
3. Boiling: The mash is boiled and hops are added for flavor and aroma.
4. Fermentation: The boiled mixture, known as wort, is cooled and yeast is added. The yeast ferments the sugars in the wort, producing alcohol and carbon dioxide.
5. Conditioning: The beer is allowed to mature and develop its flavors in a process called conditioning.
6. Packaging: The beer is filtered, carbonated, and packaged for distribution and consumption.

Please note that there are many variations and styles of beer, each with its own unique ingredients and brewing process.
