The equipment needed to make coffee by hand

The equipment needed to make coffee by hand is not bulky. Fine version of the equipment includes: bean grinder, filter cup, filter paper, hand washing pot, electronic scale, thermometer, timer, sharing pot and so on.

1 Bean grinder

There are two kinds of bean grinders: manual and electric. Hand grinder cheap, easy to clean. Electric bean grinder powder more uniform, less fine powder, uniform grinding.

Hand grinding is relatively more able to maintain the original flavor of coffee beans. Electric grinding depends on the blade, there are ghost teeth and flat knife, different blade out of the bean shape is different.

If you don't want to grind the machine by hand, it is recommended to buy an electric grinder to ensure that the coffee powder is evenly ground. If the grinding is uneven, it will make the coffee taste less pure. Because of the difference in contact area, hot water extracts much less flavor from coarser coffee grounds than from finer coffee grounds in the same amount of time.

2 filter cups

Filter cup has single hole, double control, three holes, porous, there are also large hole cup to prevent clogging, the more holes in the filter cup, the higher the flushing skills required, the material has ceramic, glass, copper, resin and so on. More commonly used trapezoidal filter cup and conical filter cup, for water injection speed master is not good novice, trapezoidal filter cup is easier to rush out good coffee.

3 filter paper

Filter paper can absorb coffee impurities and oil, so the brewed coffee color is bright and refreshing. Filter paper can be selected according to the shape and size of the filter cup. It can be discarded after one use, hygienic and easy to organize. If you are an environmentalist, you can also choose flannel filter, which can be used many times.

4 Hand washing pot

There are a lot of options for making a hand-made pot. From the material, iron, copper, enamel have; from the spout, there are thin mouth, crane mouth.

Beginners should be fit to start with a small mouth pot. The water flow of the fine-mouthed pot is easy to control, and there will be no excessive water flow, which can greatly improve the success rate of brewing. Crane-mouth pot has higher requirements for water flow control and greater freedom. It is difficult for novices to master it. After proficiency, it can be used as advanced equipment.

5 sharing pots

The sharing pot acts like a sea of tea in a tea ceremony. If one person drinks, you can put it directly on the coffee cup without sharing the pot. To extract multi-cup coffee, you need to use a sharing pot. In addition, with the scale display and transparency of the sharing pot itself, the extraction process can be better observed and controlled.

As for these three small items:

Thermometer: used to measure the temperature of water. The importance of water temperature for brewing coffee goes without saying. The kettle you use has the function of displaying the water temperature. This item can be saved. If the water temperature is too high, it will "burn" substances such as amino acids and aromatic hydrocarbons in coffee; if the water temperature is too low, it is difficult to fully extract coffee.

Electronic scale: How much coffee needs to be added to extract coffee powder, there is a certain proportion.

Timer: digitizes the temperature of the extraction.

Choose hand-brewed coffee beans

Hand brewed coffee is very particular about the choice of coffee beans. Many people grind a pile of coffee powder at a time for convenience, and others choose ground coffee powder.

In fact, when coffee is ground into powder, it will accelerate the oxidation rate of coffee powder, and the aroma will begin to dissipate in 40 seconds. If the coffee powder loses its aroma seriously, the flavor of natural coffee will disappear.

Generally choose a single variety of coffee beans from a single origin for manual brewing, more high-level ashes hand brewing players will also buy their own raw beans for baking! Roasting machines aren't cheap, so ordinary hand brewers don't have to think about buying raw beans.

In general, coffee beans do not have to blindly pursue price and fame. Choose beans with different flavors according to your preference. Only in this way can you taste the sour, bitter, sweet, fruity, nutty and richer flavors.

Coffee beans from different regions will present different flavors, so I won't go into detail here. If you like to see them, please leave a message in the comments.

Gold cup standard·hand brewed coffee

Play hand brewing, inseparable from the "Gold Cup Standard" this coffee production standard prevailing in the European and American coffee industry.

Gold Cup Theory

According to SCAE (European Coffee Boutique Association) definition Gold Cup Standard: 1000ml water, 50--65 g coffee powder, 92°C --96 ° C hot water brewed coffee. This coffee brew falls in the "bull 's-eye" position of optimal extraction rate and concentration, i.e."Gold Cup". To sum up, in order to make a high-level hand-brewed coffee, water quality, grinding degree and extraction time, powder-water ratio, water temperature are the key.

How to Make a Good Coffee

Coffee grinds to sugar fineness (less than 1 mm in diameter)

Water temperature between 92 and-96.

The ratio of water to coffee powder is between 1:15--20 (usually you can try a ratio of 1:18 before adjusting)

The contact time between water and coffee powder (extraction time) is about 4 minutes (maximum 8 minutes)

Remember, as long as the coffee extraction rate is between 18- 22% and the concentration is between 1.15- 1.35%, the coffee will not taste bad.

After saying so much, he understood the general principles. In fact, there is no need to drink a standard hand for a lifetime. Try different grinding degree, different water temperature, different tools, different water injection methods, different extraction time for hand flushing. Full of unknown coffee in the end good taste, try a few times, mouth and nose will surprise you.

Next time you have a party, try making an appointment at home and serving them hand-brewed coffee. Three or five friends, drinking while chatting, watching the mellow coffee being filtered out bit by bit, enjoy this rare coffee moment to slow down.
