Delicate "slow" life

Fast-paced urban life needs a little slow to reconcile.

Wine, flower utensils, coffee walks every day-- it's for the seven flavors of life.

"drinking coffee" is supposed to be an amorous affair.

Hand-made coffee, because of the investment of time and wisdom, there is a more sense of gift-the small and delicate gift that life gives us. A really full-bodied cup of good coffee can make the whole room smell in an instant, and the haze of life will become less melancholy because of the awakened "slow delicacy".

If your day repeats itself in the two-point-one line between work and work, and even starts to get a little as boring as instant coffee, it's time to try making coffee by hand.

01. How to taste a cup of hand-made coffee correctly

[acid]: acid can make coffee lively, light and rich. But what I hope to drink is the acid of fruit, such as the acid of apples, lemons and peaches. What I don't want is vinegar-like acidity.

[sweet]: the sweetness in coffee is not the sweetness of sugar, but the combination of caramel sweetness and caramel-like aroma.

[bitter]: there is bitterness in all coffee. Bitterness increases with the degree of roasting. If you like coffee beans that are slightly roasted, we hope to drink bitterness that will "melt" rather than taste like "charred", "carbon" and "smoke".

[aroma]: this is the most precious treasure of coffee, if there is no recognizable and clear flavor characteristics, then there is no need to choose this kind of coffee, because it is no different from other coffee.

[sense of balance]: the sense of balance is basically the synthesis of all feelings, with a comfortable taste and a pleasant aftertaste. All in all, it should be pleasant to drink as a whole.

As the grinding particles become finer, the bitterness, alcohol thickness and irritation of the coffee will increase accordingly, thus reducing the acidity.

The higher the water temperature, the higher the acidity, bitterness, mellow thickness and irritation.

The effect of brewing time on acidity, bitterness and alcohol thickness was not significant, but the irritation increased with time.

02. Seven basic instruments

It is not easy to drink a cup of hand-brewed coffee. There are at least seven basic utensils for a set of hand-brewed coffee, including filter paper, thermometer, dripping cup, hand-brewing pot, timer, weighing and bean grinder, each of which plays a vital role in the taste of hand-brewed coffee.

[hand punching pot]: control water flow and direction

[filter paper]: absorb coffee oils and impurities

[filter cup]: so that coffee can be stewed evenly

[bean grinder]: grind coffee beans to a suitable fineness

[electronic claim]: let every cup taste have a standard guarantee

[timer and thermometer]: the right time and temperature can ensure the taste of coffee.

03. Proper preservation and grinding of coffee beans

[degree of grinding]

There are all kinds of bean grinders on the market, and a good bean grinder can ensure that the coffee powder is evenly ground. If the coffee powder is uneven and the fine powder is too much, it will make the coffee taste not "pure".

What is the suitable thickness of hand-brewed coffee beans?

The answer is: moderate grinding, the size of granulated sugar. If the coffee powder is too thick and the hot water flows too fast, it is difficult to extract the aromatic substances from the coffee. If the coffee powder is too fine, the filter is easy to clog, resulting in water and powder soaking time is too long, coffee will appear bitter, astringent taste.

[freshness]

The quality of coffee beans affects the taste of a cup of coffee by more than 70%. "fresh grinding" is the first condition of good coffee, it ensures the taste of coffee.

Coffee beans taste best within a week after opening the bag. When the coffee is ground into powder, the oxidation rate of the coffee powder is accelerated, and the aroma begins to lose in 40 seconds. So brew and drink as soon as possible.

04. Water quality and water temperature of brewing coffee

[water quality]

98% of a cup of hand-brewed coffee is water. Distilled water is the best choice for making coffee.

It is not recommended to use pure water to make coffee. Coffee made with pure water often tastes dull and lacks a sense of hierarchy. But do not use mixed brand mineral water or mixed brand barreled water, once there is a strange smell in the water, it will be more obviously magnified and reflected in the coffee.

[water temperature]

Water temperature is also an important indicator that affects the taste of coffee. Too high water temperature will make coffee bitter, while low water temperature will make coffee sour.

Suggestion: deep roasted coffee beans are suitable for 80-85 degrees, while medium and shallow roasted coffee beans are suitable for extraction at about 90 degrees.

05. The way coffee is brewed.

[amount of water]

As different people have different tastes, they have different requirements for shade.

The concentration of gold cup extraction ranges from 1.15% to 1.35%, and the proportion of water used is about 1:13 to 15.

Some people use very little water simply in pursuit of richness, but it doesn't taste good. On the contrary, some people expect to extract more substances with more water, but they do not realize that the later the extraction is, the lighter it is, and the final concentration is not enough.

[cloth powder]

After the coffee powder is poured into the drip filter cup, gently shake it to make it flat. This is a step that is easy to ignore, or it is not advisable to push too hard and shake too much.

The smoothness of the flour determines the uniformity of stewing and extraction of hand-made coffee, which directly leads to the taste of the coffee.

[steaming]

Steaming is to better release the flavor of coffee beans. Good steaming can fully infiltrate the coffee powder, reduce the impurities and acidity of the coffee, and start the coffee activity.

Generally, the water used for steaming is relatively less, from the central small water injection circle to the outside until the coffee powder is wet, and then let the coffee powder expand and breathe, the steaming time is generally from 20 to 35 seconds, the steaming time of deep-baked beans is generally shortened correspondingly, and the steaming time of shallow-baked beans can be increased accordingly.

[water injection]

Whether the aroma and hierarchy of coffee can be released heartily, the key lies in water injection. Common mistakes are:

A. the injected water column is too large and the direction of the water column is too inclined. This will cause the current to flush a hole in the side of the powder layer and run away directly from the filter paper, resulting in insufficient coffee extraction.

B, the water column is pulled too high. Cause the water flow to destroy the coffee powder, easy to inject bubbles, and the coffee extraction is uneven. It will also lead to too much water column and contact air area, and the water temperature will be affected, so the water column must be as close to the coffee as possible.

C, the water flow is unstable, and the water flow is suddenly large and small. Sometimes rush, sometimes tick-tock cut off, resulting in different degrees of soaking in different areas of coffee powder, the taste of coffee will be affected.

06. To make coffee by hand

Grind coffee beans, because hand-made, coffee bean powder should not be ground too fine (20g beans = 300ml solution)

Fold the filter paper into a triangular funnel

Put the folded filter paper into the filter cup and wet it with hot water to remove the smell from the filter paper and warm the cup to prevent the coffee from suddenly turning sour (note: pour out the filtered water)

Steam, grind the coffee and pour it into the filter paper. when the hot water is cooled, pour hot water from the top of the filter cup and the water will not pass the powder.

Continue to inject water, draw a circle from the center to inject, the flow is fine and slow, and the extraction is sufficient.

When you reach the amount of coffee liquid extraction, remove the filter paper immediately.
