The skills of brewing Fine Coffee with filter Coffee

Follicular type

Definition, the roasted coffee beans will be ground, after they become smaller particles, and then its water-soluble components will be dissolved out, this process is generally called follicles.

Relationship between follicles and grinding

Stable grain size

The fever and details can be controlled to a minimum.

Select the particle size suitable for brewing.

Use of fresh grinding raw materials

The relationship between brewing and water

1, water quality

2, H2O

3. The difference between hard water and soft water

The relationship between brewing and temperature

The water temperature is too high

The water temperature is too low

The relationship between brewing and water flow

The current is too thick.

The current is too fine.

The brewing speed is too fast

The brewing speed is too slow.

Equipment, apparatus

Filter paper, filter, fine kettle, heat preservation stove, bean grinder, coffee spoon, cup machine, cooling cloth, timer, etc.

Brewing

Before water injection, warm cup, grind beans, warm pot, cool down

The first bubble, stew, cooling

Second bubble, water injection, extraction process

Too bitter

Too light

Non-concentrated alcohol

The brewing time is too long.

Temperature.

The water temperature is 100 degrees, about 97 degrees.

Cool down by 25-30 seconds, 93 degrees.

Cool down 25-30 seconds, 90-85 degrees.

To 82 degrees into the cup.

To 75-80 degrees on the guest table.

Stable grain size

It means to keep the grinding scale of coffee beans average and the same size. In the process of extraction, the water-soluble components of coffee particles are released more evenly, and the aroma of coffee itself is better played.

The fever and fine quantity can be controlled to the minimum.

This is also one of the reasons why we should choose a large and high-power bean grinder, which can ensure the stability of particle size, because the heat dissipation function of the machine is good, it can effectively reduce the heat of beans when grinding beans, and make the beans in a stable state in the blade. The chance of oxidation with air is minimized, and the content of crushed residue is controlled to a minimum under precision blade grinding.

Select the particle size suitable for brewing.

Generally speaking, the scale of acid coffee beans on the plateau is thicker, while the scale of deep-baked bitter coffee beans is finer.

The coarse grinding degree releases tannic acid and acid fat more easily under the action of water, while the fine scale releases more caramel after carbonization and the bitterness of crude fiber.

Use of fresh grinding raw materials

The freshness of the raw materials is the highest, the contact time with air is the shortest, and the aroma and volatile substances are oxidized least, so the best quality of coffee is guaranteed.

The relationship between brewing and water quality

Water quality

Water quality is an important reason related to the flavor of coffee, the water quality is softer, brewing more sour plateau Arabica species is better, while hard water is more suitable for brewing deep-roasted coffee.

Soft water

Filtered impurities, only CaCO3 and CO2, sodium ions are more than ordinary water

Hard water

In general, our tap water contains more minerals and other impurities than soft water.

The relationship between brewing and temperature

Water temperature is too high, easy to produce scorched bitterness, there will be coffee impurities, but the concentration will be very high.

The water temperature is too low, the aroma is not enough, the concentration is low.

The relationship between brewing and water flow

The current is too thick.

Can not fully extract the water-soluble substances of coffee, dilute the taste of coffee, the aroma will dilute, the flow of water in the filter will be intense, at the same time will produce more irritating smell and taste, which is not conducive to the release of coffee essence.

The current is too fine.

The astringent taste is too heavy, the flow of coffee particles is too slow, the more caffeine extracted, the bitter taste, the release of acids will decrease, and the mellowness and concentration of coffee will increase, which will produce the extremely bitter taste of excessive extraction and destroy the hierarchical sense of coffee taste.

The brewing speed is too fast, the faster the speed, the lighter the taste.

The slower the brewing speed, the slower the flavor.

The flow is high, the downward impulse is large, the brewing is intense, and the fluidity of the water is enhanced.

The flow is low, the downward impulse is small, the flow is gentle, the fluidity is slow, and the extraction time is long.
