Jamaica Blue Mountain Coffee is brewed with ice and fire. Which filter cup will taste better?

Summer is coming. There must be something cold. Today, let's do an experimental comparison between ice and fire to see if all filter cups are applicable. The editor chose a mellow [Jamaican Blue Mountain] as the experimental subject.

Let's first learn about [Jamaica Blue Mountain] Coffee!

History of Jamaican Blue Mountain Coffee:

The history of Jamaican coffee can be traced back to the 18th century, when King Louis XV of France ordered the cultivation of coffee in Jamaica in 1717, and in the mid-1920s, the Governor of Jamaica Nicholas. Nicholas Lawes imported Arabica seeds from Martinique and began to plant them in St. Andrew. Coffee trees have been introduced into Jamaica and coffee is grown in the Blue Mountains, which is divided into high-altitude Jamaican Blue Mountain Coffee, Alpine Coffee and Jamaican Coffee. Different grades also determine different prices.

The treatment method of Blue Mountain Water washing method

The peel, pulp and mucous membrane were removed by washing and fermentation. Farms that use the washing method must build washing ponds and be able to introduce an endless supply of running water. During the treatment, first remove the peel and pulp and let it ferment for 18 hours, then put the mellow beans into the pool and pass them back and forth, using the friction of the beans and the power of running water to wash the coffee beans until smooth and clean. After washing, at this time, the coffee beans are still wrapped in the pericarp with a moisture content of 50%. They must be dried to reduce the moisture content to 12-14%, otherwise they will continue to be mellow, moldy and rotten. After that, the coffee beans are screened and stored in a special warehouse. These procedures must be strictly mastered, otherwise, the quality of the coffee will be affected.

Classification and grading of Blue Mountains:

The history of Jamaican coffee can be traced back to the 18th century. The British introduced coffee trees to Jamaica and planted coffee in the Blue Mountains, which is divided into high-altitude Jamaican Blue Mountain Coffee, Jamaican Alpine Coffee and Jamaican Coffee. Different grades also determine different prices.

Jamaican Blue Mountain Coffee

Among them, there are four grades under Blue Mountain Coffee and Alpine Coffee. From top to bottom in terms of quality, NO.1, NO.2, NO.3 and PB,PB are round beans. According to CIB standards, only coffee grown above 666m above sea level is called Jamaican Blue Mountain Coffee. The best coffee is located in the Blue Mountain of Jamaica with a height of about 2000,000,2256m. Because it is located on a dangerous hillside, the output is small, the grain is large, the quality is good, the taste is harmonious, and it has appropriate sour, bitter, fragrant, mellow and sweet taste. It is recognized as the best in the world, so the price of Blue Mountain No.1 is the highest of all Blue Mountain Coffee.

The [Blue Mountain] of this experiment is 1800 meters above sea level, which belongs to the high-altitude Jamaican Blue Mountain Coffee, and it is the beans of Blue Mountain NO.1. )。

Here is our fire and ice rush!

The production method of ice and fire:

1. Put 30 grams of ice on the filter cup

two。 Put coffee powder on the ice and stand still for 1 minute

3. Steam 40 grams of hot water for 30 seconds

4. Circle water injection to about 116 grams

6. Remove the filter cup after the coffee liquid is completely filtered into the sharing pot (when the coffee liquid is still a little warm)

7. Add 70 grams of ice to the sharing pot.

Parameters: 18g coffee powder / 88 ℃ / 1 12 / moderate grinding (BG 5R: Chinese standard No. 20 sieve pass rate 58%); in order to make a better comparison, the editor tries to unify the parameters and methods as much as possible.

[V60 filter cup]

Flavor: caramel, spices, vanilla, nuts, cocoa, cream, berries; rich overall feeling, rich nutty flavor.

[trapezoidal filter cup]

Flavor: berries, passion fruits, caramel, cream, chocolate; the overall feeling is relatively thin, the flavor is not prominent.

[cake filter cup]

Flavor: berries, sugar, brown sugar, cream, chocolate, the overall feeling of fruit juice is more obvious, nut flavor is weak.

Total knot

The purpose of ice and fire is to use the low temperature of the ice to cold extract the coffee powder, and then rinse it down with high temperature water, so that the aroma excited by the coffee powder can be cooled immediately and the aroma of the coffee can be retained. And in the process of steaming, the ice can basically melt.

The editor feels that [Jamaica Blue Mountain] is more expressive in [V60] and [cake filter cup] in different instruments.

This may be because the coffee powder in [V60] is more concentrated, and the contact between water and coffee powder is longer, so the water level does not drop much after steaming for 30 seconds, and then continue to inject hot water to increase the soaking time of coffee powder. In addition, [V60] is a tapered filter cup with ribs next to it to help drain, so it has more layers of powder in the middle and less on both sides, so the extracted coffee is more layered.

[cake filter cup] is flat-bottomed and poured into coffee powder after adding ice, the distribution of coffee powder is not very uniform, but this filter cup belongs to semi-immersion extraction, soaking time is longer, so there is no uneven extraction, and the bottom of the filter cup is 4 holes, so the flow velocity is relatively uniform. Therefore, the matter dissolved in water is similar, and the water saturation is higher, so [Blue Mountain] it will have a stronger sense of juice and a higher thickness of alcohol.

[trapezoidal filter cup] because the shape of the filter cup is trapezoidal, and its ribs help to drain the water, the low filter cup is a three-hole design, so the flow rate of coffee liquid is faster in the brewing process. [blue Mountain] Coffee doesn't have the advantage of mellow taste here, but it has a strong nutty flavor and soft acidity. Therefore, the editor thinks that the trapezoidal filter cup is not suitable for ice and fire flushing.
