How to calculate the gouache ratio of hand-made coffee?

Practical parameters of gouache ratio of hand-brewed coffee

[heavy flavour] 1VOG 10ml Coffee Bean weight 1ml Coffee Coffee 13.5 (Bean weight ratio unboiled Water ml)

[moderate taste] 1-12-12-1-13 (I. e. 1-14. 5-1-15. 5)

[refreshing] 1-14-1-1-1-16 (I. e., 1-14-1-1-18. 5 of the Golden Cup Criterion)

The scale is right, but the brewing proportion is not right, and it is not easy to make delicious coffee. In the process of learning, we need to drink repeatedly and test the concentration. It is found that the best brewing ratio, that is, the amount of coffee beans is higher than that of black coffee, which is between 1 cup, 12 grams and 13 milliliters, which is equivalent to the four major gold cup systems in Europe and the United States. the yield of coffee beans is 14.5 grams 115.5 per gram of raw water, and it is most likely to hit the golden range of 18% 22% and 1.15% 1.35% of the "golden cup moment". Instead of brewing espresso with tangled flavor spectrum or thin coffee with too strong water flavor.

It is believed that the brewing ratio of most hand-brewed coffee lovers should fall within this range. Our most commonly used hand-brewing ratio is 1-15-15-1-16, that is, the "golden cup" criterion of 1-15-1-1-1-18. 5.

Of course, some hand-brewed coffee lovers use a more extreme brewing ratio. For example, those who like heavy flavors are often hand-brewed at 1:10 (that is, the golden cup ratio is 1-12.5), using a higher concentration to make up for the deficiency of extraction, that is, only to extract low molecular weight and medium molecular weight sour and sweet flavors, to avoid the extraction of high molecular weight bitter substances, although it can also make mellow delicious coffee, but the concentration is too high. It is not easy for ordinary people to accept, and it is too wasteful of coffee powder to be encouraged. In fact, a better coffee can be made at a more normal 1:12 (that is, a golden cup ratio of 114.5%).

Interestingly, there are also some light coffee lovers who like to brew by hand in a diluted proportion below 1:14, but do not underestimate these coffee lovers, whose taste buds may be sharper and can be appreciated in a variety of layers from the thinner coffee liquid. If you have to use 1:10 to brew in order to feel good enough, it may be that the taste is too dull and depends on high concentrations to stimulate it.

Step 1: prepare the equipment

Soldiers need a hand-lined weapon to fight a war, and so is making coffee. The necessary equipment is "hand-made pots, filter cups, filter paper, sharing pots, and bean grinders."

Novice set: hand-washed pot filter cup filter paper sharing pot bean grinder

Advanced set: hand-washed pot filter cup filter paper sharing pot bean grinder sealed can electronic scale thermometer timer

Open hanging set: gold-plated hand punch pot, gold-plated filter cup, gold-plated filter paper, gold-plated sharing pot, gold-plated bean grinder, gold-plated seal pot, gold-plated electronic scale, gold-plated thermometer, gold-plated timer (gold Saint, price per cent, gold-plated timer, the more expensive the equipment, the better the quality is real, and there is a lot of room to play)

Hand punch pot

Hand brewing pot is necessary for hand brewing coffee. When choosing a hand brewing pot, you need to consider "the stability of water flow, the heat preservation of the pot body and the safety of the handle". Different designs of the body and spout of different hands will bring different effects, the first condition is actually suitable for their own hands to hold, with accustomed to better control the flow of water, make delicious coffee.

A few simple recommendations:

1.tiamo dripping type fine kettle

Flow control: ★★★★☆

Thermal insulation performance: ★★★★☆

Difficulty in getting started: ★☆☆☆☆

This one also has a color version, which feels great to the touch after using it.

2. Kalita crane mouth pot

Flow control: ★★★☆☆

Thermal insulation performance: ★★★★☆

Difficulty in getting started: ★★★☆☆

This is also a favorite of many people. The crane mouth is designed to make the current finer and more stable, but the only drawback is that girls may feel a little heavy.

3. Hario stainless steel hand punching pot

Flow control: ★★☆☆☆

Thermal insulation performance: ★★★★☆

Difficulty in getting started: ★★★★☆

Simple design, the flow can be large or small, but need good practice to ensure the stability of the flow, also divided into two versions.

4. Bonavita electronic temperature control hand punch pot

Flow control: ★★★☆☆

Thermal insulation performance: ★★★★☆

Difficulty in getting started: ★☆☆☆☆

This electronic temperature control, with a chip, set the temperature will stop by itself, and the thermal insulation function, the ergonomic design makes it feel light when holding, and the new version of the limited flow valve in the kettle makes it better to control the flow of water.

Filter cup

Used to match the filter paper to filter coffee grounds, you can also directly buy the filter cup of the metal filter screen, the advantage is that you do not use the filter paper as a consumptive material, but it is a little troublesome to clean, and there is not enough room to adjust the cooking mode during the operation. Different brands of filter screen thickness will be different.

Several recommended ones:

V60: the one with the highest utilization rate, fast flow rate, diversion line, suitable for most coffee beans

Kono single hole: my favorite, slightly slower, suitable for African beans and Central and South America

Kalita fan-shaped single hole: slow flow rate, also suitable for many coffee beans, can show better alcohol thickness

Sharing pot

Can be used to hold coffee, there is a scale to meet their preferences on the line, if not at least need to have a scale, because the powder-to-water ratio is involved.

Powder / water ratio, that is, the ratio of coffee powder to water, those who like lighter ones can use 1:18. Those who like thicker ones can use 1:13. The middle of coffee taste is 1:15. The taste of coffee, as an act of perceptual existence, still needs to be adjusted according to its own taste preferences. My favorite 1:13 may not be your favorite 1:15 at 1:8. I'm sorry, I played with tongue twisters.

Bean grinder

In commercial equipment, bean grinder occupies a very important position, coffee powder grinding thickness and uniformity will affect our hands of coffee, usually classified by the type of cutter head to distinguish: flat knife, bevel knife, rail teeth.

No matter which kind can make good coffee, flat knife, rail tooth grinding is more uniform, extraction will be more uniform, cone knife cutting surface is different, will bring more layering. But do not choose a broken bean grinder, rather than a bean grinder, grinding is difficult to ensure uniform, the thickness is very uneven, will lead to the taste is too complex, sometimes there will be a dirty feeling.

Sealed tank

If coffee beans are not used quickly, they should be kept in sealed cans, away from sunlight and exposure to high temperatures.

Electronic scale

The scale is used to weigh the quality of powder and the quality of water injection to better control the ratio of water to powder.

Thermometer

For precise control of water temperature, it is necessary to brew it with a suitable water temperature. if there is no thermometer, open the lid and rest for two minutes before use. too high temperature will bring out too much substance in the coffee, including bad temperature. on the contrary, it will make the coffee too "talkative".

timer

Used for accurate timing. The longer the time, the more substances are extracted, which is similar to the temperature, and the shorter the time is, the lighter the taste is.
