1. Spread the Santos raw beans sparsely in the baking tray to make room for the coffee beans to expand due to heat.
2. Preheat the oven to 100 degrees Celsius, put it in the coffee bean roasting tray, and dehydrate for 15 minutes. During the dehydration process, the coffee beans emit a bean aroma and gradually turn into yellowish brown. Adjust the temperature of the oven to 150 degrees and bake for 5 minutes; then adjust the temperature of the oven to 190 degrees and bake for 3 minutes; after the fire-promoting stage, the coffee beans darken quickly and enter the first burst period.
3. 50 seconds after the first burst, take out the coffee roasting tray and take out half of the coffee beans to dissipate heat to preserve the fruity aroma of Santos. The other half of the coffee beans is quickly put back into the oven to continue roasting.
4. The other half of the coffee beans are roasted again for 90 seconds, and when they are about to burst, they are taken out, mixed with the first half of the beans, and laid flat to cool down.
5. The coffee beans are ground to a fine powder without removing the silver skin.
6. Pour 300ml of hot water (2 cups) into the lower pot of the siphon. The body and bottom of the kettle must be wiped dry to avoid explosion during heating.
7. Hook the filter element on the siphon pot.
8. Light the alcohol lamp.
9. Insert the upper pot of the siphon pot obliquely into the lower pot, and the alcohol lamp heats the lower pot.
10. After the water in the lower pot boils, it rises to the upper pot.
11. All the boiling water rises to the upper pot. After the bubbles become small, add 30 grams of Santos coffee powder and brew for 3 minutes (when brewing, use a stir bar to gently press the coffee powder into the water).
12. Turn off the alcohol lamp.
13. As the temperature of the kettle body decreases, the coffee in the upper kettle is automatically filtered into the lower kettle.
14. Wait for the coffee in the upper pot to filter into the lower pot.
15. Pour the brewed coffee into the cup. It retains the fresh taste of Santos lemon and berries, with a rich chocolate aftertaste.
