1）What is hand brewed coffee?
Literally: hand-brewed coffee.
Hand brewed coffee was invented in the early 20th century by the German lady Melita.
At the time, the traditional European way of making coffee was cumbersome and Melitta, who loved coffee but was frustrated by it, wanted to invent a more convenient and simple way of making coffee.
Mrs Melita, who had always been a housewife, just happened to come across her son’s school workbook.
With a stroke of genius, she made the world’s first coffee filter from the ink paper in her homework book and accidentally produced a cup of coffee that tasted like nothing else!
The joys of hand-brewed coffee
The human taste buds can only taste the acidity, sweetness, bitterness, saltiness and freshness of coffee though.
But the human sense of smell is, on the contrary, much more powerful. The average person can distinguish between a dozen different smells, and with olfactory training, the best people can remember around 3000 smells.
And so the question may be asked, “Why does coffee smell good, but not taste good?” So rather than drinking coffee, drinking coffee is actually an olfactory pleasure.
The volatile aromatic substances in a small coffee bean are the main source of coffee flavour and can only be perceived through the human sense of smell. Hand brewed coffee has many different brewing parameters and techniques, but even if the parameters are replicated, different people will have different flavour profiles.
So sometimes, if you want to drink your favourite hand brewed coffee, you may want to make it yourself to get the cup of coffee to your liking faster, after all, not everyone brews coffee to their liking.
This is the fun part of hand brewing coffee. It is also the reason why many coffee lovers are fascinated by “hand brewed coffee”.

How many types of filter paper are available for hand-brewed coffee?
The filter paper is the filter medium for hand-brewed coffee and is often the most overlooked detail.
There are different grades of filter paper, and poor quality filters will leach the taste of the pulp into the coffee. There is a wide range of filter papers on the market today, with materials such as hemp, bamboo, cotton and high grade Japanese washi paper, etc. The length of the fibres in the filter paper also affects the flavour, and some thicker filter papers can also modify the flavour of the coffee. For example, Chemex filter paper from the USA is thick enough to filter out most impurities and may taste better than other filter papers.
Bleached filter paper vs unbleached filter paper：
Coffee filters are mostly made from wood, which is mostly brown in colour after steaming and has to undergo several stages of bleaching before it becomes white.
The difference between bleached and unbleached coffee filters is as follows.
1, bleached: refers to the coffee filter paper has been bleached, the filter paper looks whiter.
2, unbleached: refers to coffee filter paper has not been bleached, the filter paper looks close to light brown
Raw wood coloured filter paper, compared to white filter paper, less bleaching process, but the filter paper itself paper taste increased, need to pay attention to fully wet the filter paper with boiling water when brewing coffee, some at least 2 – 3 times wetting, in order to reduce the taste of paper into the coffee
Bleached filter paper has strict requirements in terms of material selection, process and quality control, mainly nowadays bleaching is done with enzymes, which are biologically active enzymes and are widely used in the pharmaceutical field, the degree of harm is negligible.
The choice of the right filter paper can be made by considering the following four factors.
Stiffness: filter paper gets wet when filtering. For long filtration procedures, a tougher filter paper with wet water should be considered.
Filtration efficiency: The sparseness and size of the small permeable holes in the filter paper affect its filtration efficiency. A high efficiency filter paper is both faster and has a higher resolution.
Capacity: The solid particles that accumulate during filtration may block the pores on the filter paper, so the more densely packed the pores are, the higher the capacity and the more filtered text it allows.
Applicability: Some filter papers are made using special manufacturing procedures, for example in pharmaceutical testing for the determination of nitrogen in blood, nitrogen-free filter papers must be used.
Note that the filter paper should not be filtered with zinc chloride, otherwise the paper will be corroded and damaged by the zinc chloride.
What is the difference between coffee filter paper #2 and #4?
The correct term for the size of coffee filter paper models should be 101, 102, 103, 104
101 is for 1 to 2 people
102 is for 2 to 4 people
103 is for 4-6 people
104 is for 7-12 people
This means that the larger the model, the larger the filter capacity and the more coffee you can make at once.
Of course, the size of the filter cup you want to buy depends on the size of the filter.
How do you use the fan and V-shape?
I. First of all, when using filter paper to brew coffee, you need to do some basic preparations: 1. prepare the ground coffee powder; 2. fold the bottom of the filter paper upwards and then fold the sides of the filter paper outwards. When placing the filter paper in the cup, press it gently with your fingertips to make it fit perfectly on the cup, without any seams. Then add the coffee powder and smooth out the surface.
II. For the first time, bring the boiling water to the right temperature (82-83 degrees) and then pour it evenly over the coffee powder in a special kettle (if you don’t have one, you can use a black tea kettle instead), never letting air into the hot water at this point, because once it is mixed with air, there is no way to fully infuse the coffee into the hot water. The measure is to maintain a certain flow of water when pouring, and the way you pour the hot water should be from the centre to the periphery, roughly in a (spiral) pattern, until the whole of the coffee powder is soaked in the hot water. (Note: about the level of a few drops falling onto the coffee pot)
III. The first time you pour the hot water, the surface will swell up like a burger, maintain this state for 20-30 seconds (about the time when the hot water is almost gone), then pour the hot water a second time. This is poured on the outermost edge of the coffee filter paper, and do not let the coffee powder on the edge of the filter paper rise up.
IV. Pour hot boiling water for the third time, then pour hot boiling water for the third time before the second pour is almost gone, and repeat in the same way until the desired amount is reached, and remove the cup before it is all gone. If you want to heat it up, do not boil it until it comes to a boil.

2）Where does paper drip coffee come from?How was the locket coffee invented?
Many people are unable to try a delicious black coffee all the time because it is too tedious to brew a cup of coffee. But the advent of hang-ear coffee has changed that.
The invention of the drip hanging ear coffee bag
Now, it’s not difficult to get your hands on a coffee bag (also known as a filter coffee), which is available on major e-commerce shops, supermarkets and most coffee shops. But do you know which country first invented the coffee bag? It wasn’t the mature coffee markets of Europe and America, but Japan, which is close to China.
When you think of Japanese coffee, most people think of hand-brewed coffee, and indeed, hand-brewed coffee is quite popular in Japan, but young Japanese office workers with a fast pace of life don’t have time to wait for a cup of hand-brewed coffee.
With the hanging ear coffee pack, all you need is hot water and a decent sized mug and you can enjoy a good cup of coffee anytime, anywhere.
So, in 1990, Yamanaka Sangyo Ltd. took the concept of tea bags and applied it to coffee, inventing and patenting the locket coffee. However, the hang-ear coffee bag designed by Yamanaka Sangyo could not bear the weight of brewing coffee and tended to lose its balance during the brewing process, so it was not successfully commercialised. It was only in 1998 that Oki Corporation improved on the original invention by extending the lug part outwards, resulting in the lug coffee of today.
The market for hanging ear coffee bags
The Instant drip coffee bag is a quick and easy way to enjoy instant coffee without the need for a brewing appliance, and it also offers the pleasure of hand brewing.
The combination of instant coffee and hand brewed coffee has led to the rapid growth of the Instant Drip coffee bag in the East Asian market. In 2011, 1.4 billion sachets, or approximately 11,200 metric tonnes, were sold worldwide, with 94% of these sales coming from Japan, where Starbucks has also launched the sachets specifically for this market. Although total worldwide sales of hang-loop coffee packets are currently small and the market is relatively small, it is growing very fast.
In the past, the market share of instant coffee in the brewed coffee market was as high as 70%, while the market share of hanging coffee was only 10%. However, in recent years, due to the food safety crisis and the rise of boutique coffee, coffee consumers are no longer just looking for a refreshing coffee, and the combination of quality and convenience of hang-loop coffee meets consumer demand.
With the continuous advancement in packaging technology, the hang-ear coffee pack has been able to completely isolate the outside world from oxygen. So as long as the beans themselves are of good quality and consumed within the best tasting period, the best thing about brewing locket coffee is that the professional barista has already set most of the variables for you, so you don’t need to choose the beans, consider the water to powder ratio and the coarseness of the coffee powder, nor do you need a brewing appliance and expert skills, all you need is hot water and a good sized mug and you can enjoy good coffee anytime, anywhere.
