1, hand-made pot: the size of the pot mouth will affect the brewing effect, because the pot mouth controls the water output. Beginners suggest using a small-mouthed pot, which makes it easier to control the water output.

2. Filter paper: Filter paper can absorb some impurities and oils of coffee. There will be some paper smell after bleaching, but it will not affect the taste of brewing. The thicker the filter paper, the slower the flow rate of the extract and the longer the interaction time between hot water and coffee powder.

3. Bean grinder: freshly ground coffee is the freshest, and the granularity and uniformity of coffee powder are also the key to affect the flavor of hand-brewed coffee. The powder suitable for hand-brewing coffee is about the size of No.2 sugar. The more uniform the particles, the better the taste of the brewed coffee.

4. Auxiliary equipment: electronic scales, thermometers and timers can make the process of making coffee more accurate.

5. Water temperature: The higher the water temperature, the faster the extraction speed. It is generally recommended that deep roasted coffee beans be brewed at 80-90 degrees, and shallow roasted coffee beans be brewed at 90-97 degrees.
