2. Don't reheat the brewed coffee. The temperature to keep the best flavor of coffee is 86℃( 185℉).
3. Brew with fresh water. The suitable amount of water per cup is 98%. If there is an odor in the water, you can consider filtering it with activated carbon.
Please don't reuse the ground coffee powder, because the bitter ingredients in coffee will remain in the brewed coffee powder.
5. Please use the correct grinding degree provided by the coffee manufacturer. Grinding too fine will lead to excessive extraction, bitter taste, or blockage of infusion equipment. Insufficient grinding will cause lightly ground coffee to be like water. If a drip brewer is used, the dripping process should be completed within two to four minutes, which is an appropriate grinding degree.
6. It is recommended to use10g ground coffee per180ml (6 ounces) of water. No matter how much coffee you want to make, you should make it in the same proportion.
7. It is best not to let the coffee stay in the coffee machine for more than 20 minutes. If it is kept for too long, it will lose its flavor. It is recommended to use a thermos pot or vacuum pot to keep coffee warm and fragrant for a long time.
