The basic knowledge of brewing coffee

Siphon grinding method: medium and fine

The siphon pot is a method of using steam pressure to extract coffee. What is interesting is that it can fully see through the process of coffee extraction. After boiling, the boiled water in the flask evaporates directly into the funnel, and the coffee extraction process is completed. The extracted coffee flows into the flask again, as if it is a dramatic performance, not only in taste, but also visually satisfied.

Brewing steps:

Pour the water into the flask, light the alcohol lamp at the bottom, heat it, install the filter on the funnel, pour in the right amount of coffee powder, boil the water, and insert the funnel above the flask (if the water temperature is low, the taste will get worse) after heating, the water evaporates and rises to the funnel. Under pressure, the coffee powder will float above the boiling water and stir the coffee powder deposited below with bamboo slices so that it can completely dissolve and soak in boiling water for 30 seconds, then stir slowly in a concentric circle in the funnel for 6-7 times for 45 seconds, then turn off the alcohol lamp, the coffee in the funnel will flow down to the flask after filtering through the filter, and it is done.

Filter paper brewing grinding method: medium and fine

Brewing with filter paper is the most easy and hygienic way to brew coffee, and without buying expensive equipment, you can use the easiest way to make coffee at home, and another advantage is that it is easy to adjust the amount of coffee powder. Hot water quantity and injection method.

Use a kettle to select a fine spout for brewing. Hot water can be injected vertically, and the pot is filled with 7-8 minutes of hot water. When boiling water, pour slowly when the number of coffee is small, and pour faster when the number of coffee is large, so that strong coffee can be brewed.

Brewing steps:

Bend the sealing line of the special filter paper for coffee interactively and put it in a drip coffee pot; put 10g coffee powder in a cup of coffee, gently shake the coffee pot and let the coffee surface level; carefully pour boiling water on each inch of coffee powder; in order to extract the delicious ingredients of coffee, it is necessary to ripen for about 20 seconds; depending on the amount of coffee, put the right amount of hot water from the center to the center.

In order to prevent the hot water from overflowing, when the hot water rises to the upper half, pour it into the coffee cup quickly before the hot foam disappears.

Flannel filter drop bubble grinding method: medium

Its bubble method is more or less the same as filter paper, but the coffee taste is more detailed, it can make the coffee bitter. Sour taste and other characteristics are completely presented, but the inconvenience of flannel filter is in maintenance, cleaning and finishing. When using it for the first time, rinse it with hot water, then boil it in boiling water soaked in coffee powder or tea dregs for 10 minutes to remove the stench of the cloth, then rinse with water, rinse clean with hot water after use, soak in cold water and store. Remember not to use soap or dry directly, otherwise it will produce a bad smell. When refrigerated, it is best to put it in an airtight container so as not to stain the smell of other foods.

Brewing step: remove the filter from the water, gently wring the water with your hand, pour the coffee powder into the filter with the plush facing outward, gently shake, drop the boiling water into the coffee, from the center to the surrounding, do not inject too much at one time, lest the coffee powder begin to expand, produce fine foam from the filter and lower a few drops of coffee liquid from the filter. When the coffee liquid becomes light brown, remove the filter immediately. Sometimes the foam is mixed with impure substances, the taste of the coffee will get worse, after the extraction, the central part will not sink, and there will be no foam left on the surface.

Water drop grinding method: fine

It mainly uses coffee to dissolve with water and slowly extract it from the water. because it needs to be extracted drop by drop in a coffee distiller, it takes a long time, and the taste of the coffee varies with the degree of roasting. The amount of water. The time is different, so it is suitable for deep-baked coffee beans, otherwise the sour taste will be too strong.

Brewing steps:

Pour the water into the kettle and fix the filter paper in the cylinder filter tube, put in the coffee, and fix the coffee powder by the upper light pressure. All the coffee powder is soaked in the filter tube and assembled with the cup that receives the coffee powder. Adjust the drip suppository (about 40-42 drops per minute) in about 5-6 hours.

Iced coffee grinding method: fine

Brew the coffee liquid in either way, but the concentration should be twice the concentration of hot coffee. Pour ice into the glass and add coffee to freeze quickly. Or put the coffee pot in cold water to cool, and then put in the refrigerator to refrigerate, but it should be noted that the cooling time is too long, it will form ice or cause taste deterioration.

Mix sugar juice

The blending method of sugar juice is to melt sugar and water at the ratio of 4:6 to make it cool naturally. It should be noted that too much water will make the coffee taste lighter, and too little water will not be easy to dissolve with the coffee. After blending, you can keep the sugar machine in the refrigerator for a while.
