Past lives in the "Merita" filter cup

Click on the attention | Friend A said with a heart.

In the early days, people didn't need to filter cups when drinking coffee. The method is also simple and rude: pour coffee powder into the pot, boil it, precipitate coffee grounds, and then drink it, just like Turkish coffee. Although this method could not avoid the appearance of coffee grounds, it lasted for hundreds of years until the appearance of cowboys in the western United States. Cowboys put metal wires on socks in a circle, pour coffee powder into socks, and then make coffee with boiling water, hence the famous nickname "sock coffee". This kind of coffee is purer, and it is also the source of filter cloth coffee. This can be seen as a prelude to the emergence of filter cups.

Ben Ci Merita, many coffee lovers will feel strange when they hear this name, but she is the most important woman in the history of coffee. The copper coffee filter cup she invented has influenced the coffee industry for a hundred years. Ben Ci Merita was born in Dresden on 1873. She has a hobby, which is making coffee. As a perfectionist, coffee grounds left between teeth often bother her. How do we get rid of these coffee grounds? One day, on a whim, she made a hole in the bottom of the copper bowl, took out a blotting paper from her son's schoolbag, put it on it and rushed into the hot water. Suddenly, mellow coffee dripped into the pot through blotting paper. In this way, she invented a filtering method, which can filter the residue and retain the aroma of mellow coffee.

Before this invention, people used cloth bags to filter coffee grounds. However, cloth filter bags are troublesome to clean and unsanitary after being used many times. The residual coffee grounds in the gap of the bag easily destroy the original mellow taste of coffee.

1On June 20th, 908, Merita registered her invention in the Royal Patent Office: an arched copper coffee filter cup with a water outlet hole at the bottom, which is the first filtered coffee cup in the world. Merita Ben Ci set up Merita Company in her own residence with little money at that time, and took her autograph as the registered trademark of the product. Unfortunately, there are few records about Ben Ci Meletta in German local archives, and we have no way to know more information. But this great invention soon became a household name and eventually became a necessity in German kitchens.

In the mid-1920s, orders came from all over the world, and the business of making Merita coffee filter cups expanded rapidly. However, the original family-owned company could not accommodate the production order of 65,438+000,000 filter elements, including ceramic filter elements, and the company moved to Minden in 65,438+0929. Today, Merita is still run by the grandsons of its founders. Merita now has 50 branches around the world with more than 3,200 employees. Hand-washed filter cups have also been improved towards automation. After numerous improvements, it has finally achieved great success in the United States. This is the most popular automatic filter for American coffee that we see now. However, if you take apart an American coffee machine, the principle of the filtering method invented by Mrs. Meleta has hardly changed so far, only the shape of the filter and the filter paper are optimized.

Today, 565,438+0% of German families have a classic filter paper drip coffee automatic machine, and 6% of them often use Meleta's early antique filter cups to brew a full-bodied German coffee. However, it is undeniable that in the modern fast-paced information society, this method of brewing coffee by hand 100 years ago has been less and less used by people in Germany and Europe, but this ancient coffee brewing method has miraculously taken root and blossomed in the East, especially in Japan, South Korea, Taiwan Province Province of China and inland areas.

It is particularly worth mentioning that since the 1950s, the Japanese have been fascinated by Merita filter cups, and various coffee filter cups with filtration and drip filtration have emerged one after another. They also established a set of theories and operating techniques for hand-washing filtered coffee, which has been loved by more and more people. It really answers the proverb "The East does not shine, and the West does not shine".

Merida filter cup, the upper body is fan-shaped, the upper circle is oval, and there is only one filter hole at the bottom. The powder wall inside the filter cup is a strip-shaped protrusion-generally called a rib or rib, with only a small hole at the bottom. This is a Melita filter cup.

There is a common misunderstanding that the trapezoidal filter cup is slow to enter the water. In fact, the main reason is that most filter cups don't have as deep grooves as Melitta at that time, which is easy to block holes. At the same time, if the groove is too shallow, the filter paper will stick to the wall of the filter cup. In the steaming process after hot water is injected, air has no exhaust way, and it is easy to rush out of the steaming surface like a volcanic eruption, which makes a hole in the powder surface and cold air enters, resulting in incomplete steaming. The deep groove design of antique Melitta cup avoids this problem well. The coffee brewed by Melita has a clean taste, and the mellow degree of flavor has been fully displayed, highlighting the subtle flavor. The ceramic conical filter cup can keep the temperature well during the brewing process and create a soft and fresh taste.

Filter paper can absorb a part of coffee odor and a lot of coffee oil at the same time, so the brewed coffee is bright in color and refreshing in taste, which is probably an important reason why Japanese and orientals prefer to use filter paper.

The metal filter screen is really convenient, which saves the trouble of using filter paper every time and the cost of buying filter paper. However, no matter how fine the filter screen is, there will always be a small amount of fine powder dripping down with the coffee liquid. Therefore, the Japanese who pay attention to the extreme also have a special ultrasonic vibrating cup for filtering fine powder, and the fine dust of coffee powder is filtered out by the filtering vibrating cup before brewing. The coffee brewed by metal filtration retains coffee oil, so it can be as close to the original taste of coffee as possible, so the taste is richer and mellow than filter paper, which is very important for some people who pursue the original taste of coffee.

1. Clean the conical container of coffee equipment after each use.

2. After use, discard all the remaining coffee powder in the coffee container.

3. The manual coffee machine should be kept clean and in good condition.

4. The conical filter of hand-brewed coffee equipment should be kept clean and in good condition.

The kettle should be kept clean and in good condition.

6, will spill or spill clean, all day in addition to the material processing.
