SCAE Standard hand Coffee course Coffee basic knowledge

Hand-brewed coffee is the "third wave", that is, the most popular way of brewing coffee in today's boutique coffee era. both its production method and coffee flavor are worthy of in-depth study and discussion.

We should thank the German wife Melitta for this popular way of brewing coffee in the world. She invented the coffee bubble method more than 100 years ago, which changed the way the world drinks coffee. Before this invention, people used cloth bags to filter coffee grounds. However, the cloth filter bag is troublesome to clean and unhygienic after being used many times, and the coffee grounds left in the gap in the cloth bag are also easy to destroy the original mellow taste of coffee. On June 20, 1908, Melita registered her invention with the Royal Patent Office: a copper coffee filter cup with a water outlet at the bottom, the world's first follicular coffee cup. At that time, Mrs. Melita set up the "Melita Company" in her home with a small amount of money, and used her autograph Melitta as a registered trademark of the product.

Like siphon coffee, with the rise of the boutique coffee market, hand-brewed coffee has ushered in its first spring. In the United States, Bonavita is recognized as the only equipment designated for brewing coffee, and has been repeatedly recognized as the designated coffee brewing apparatus for top international events. With its unique innovation, excellent quality and attention to customer needs, it has been a great success as soon as it is listed. Among them, Bonavita gooseneck type adjustable temperature electric hand brewing pot and cup measuring pot are the only two coffee utensils of the same kind in the world that can accurately control the temperature (plus or minus 1 degree Celsius). Now it has been officially introduced into China, let's work together to promote boutique coffee.

This time we use Bonavita gooseneck temperature-controlled hand brewer and freewheeling cup filter cup to make coffee for two.

Preparation utensils: Bonavita temperature control hand flushing pot, electronic scale, random cup filter cup, coffee pot, filter paper, bean grinder

Coffee powder VS drinking water ratio:

1. 150ml porcelain cup = 160ml water + 9g coffee powder

2. 300ml porcelain cup = 321ml water + 18g coffee powder

3. 360ml porcelain cup = 482ml water + 27g coffee powder

Operation steps:

1. Folding filter paper:

Take out the "Melitta4 filter paper". Its side and bottom are pressed by the machine and are thicker. Filter paper selection: filter paper is divided into size types, according to the choice of filter cup, bleached and raw pulp filter paper, here according to your own needs.)

First fold the side of the thicker filter paper pressed by the machine and flatten it.

Then fold and flatten the bottom of the thicker filter paper pressed by the machine. (note: be sure to fold from the back)

Finally, the folded filter paper is placed in the filter cup.

two。 Grinding: hand-operated bean grinder to grind coffee beans (the coffee powder is about sugar, and the thickness is uniform.)

3. Turn on the toggle switch, place the filter cup on top of the coffee pot, pour hot water into the cup, and wet the filter paper. After releasing the hot water, turn off the switch.

Note: (the function of soaking filter paper is not only to let the filter paper stick to the cup wall, but also to wash away the "pulp smell" of the filter paper, so please turn on the switch to perform the action of soaking filter paper)

(the water temperature range of hand-brewed coffee can be 85-93, but the taste of different water temperatures must be very different. Different beans need different water temperatures for different roasting degrees, and players need to adjust themselves to find the most suitable water temperature.)

4. Put the filter cup that turns off the switch on the electronic scale and return to zero, put in 18g coffee powder, pat the side and flatten the powder.

Then return the electronic scale to zero (it can be called pre-stuffy steam).

5. Pre-stuffy steaming for the first time:

Inject 321g of 10% hot water, that is, 32g of hot water (be sure to pour through the surface, but do not drop too much water in the pot); at the same time, press the timing switch of the electronic scale and soak for 20 seconds (be sure to be synchronized with the injection of hot water)

Return the electronic scale to zero (before it can be called the amount of water for the second injection)

6. For the second water injection, 321g of hot water is injected with a smaller flow (mainly based on the ratio of water to powder in the above schedule).

Pour water directly into the pot by hand, without paying attention to gestures, it is recommended to start the injection from the midpoint, and then draw concentric circles in one direction to the outside, but remember to wet all the coffee powder, do not have dry powder, and do not flush the water out of the concentric cup. (note: do not flush to the filter paper, otherwise it will cause damage to the coffee powder wall and cause water hole)

7. Finish the extraction: cover the top of the corral cup and steam for 3 minutes

Turn on the free cup switch and inject the coffee liquid into the coffee pot. The whole brewing process takes about 3.5 minutes (be careful not to let out the foam at the bottom of the cup).

8. Enjoy the delicious coffee: pour the coffee from the coffee pot into a warm coffee cup and you can enjoy the warm and delicious coffee.

Bonavita is a high-end brand from the United States, belonging to international professional coffee utensils, using it to make coffee is really a luxury.
