How to brew hot coffee
Preparation
Let's prepare the beans ☕️.
We recommend medium to coarse ground beans for brewing coffee.
(Step1) Drain the filter with hot water.
First, raise the temperature of the filter by pouring hot water over it briefly.
The filter is usually cold so if you pour coffee through it as is, the coffee will be cold as it is extracted.
(Step2) Set the filter
Set the filter on top of the server or cup you wish to brew coffee.
Here is the set-up.
Without the protective holder, set it as shown below.
If you have a protective holder, please set it up like this.
*Protective holders have two sides. If the front and back are set correctly as shown in the photo, the protective holder will not easily slip out of place and will be easier to set.
(Step 3) Put the beans in the filter.
Just put it in here briefly, and then just tap the filter to flatten it out and you're good to go!
(Step 4) Let's brew the coffee right away!
First, pour hot water over the entire surface just enough to let the hot water sink in fully.
Then steam for 1 minute.
After 1 minute, just pour the rest of the hot water over the entire cup and it is ready to serve 😊.
Advanced users often experiment with roast degrees and extraction speeds to suit their preferences, depending on the characteristics of the ceramic filter.
Later on this page, we will also show you more detail tips about how to brew more delicious coffee with ceramic filters.

After brewing
After brewing, wash it as soon as possible to make subsequent care very easy.

How to brew iced coffee
When brewing coffee with water
To brew coffee with water, follow these steps.
|
1. Put about 50g of ground coffee beans in a coffee server and pour 400-500ml of room temperature water (you can adjust the amount of beans and water if you'd like.)
|
This way, you don't need any special pot to brew coffee, so you can try it out with what you have at home!
When brewing from hot coffee
This is a method of brewing hot coffee and cooling it down to make iced coffee.
When you want to drink immediately
If you want to drink it right away, the fastest way is to cool the hot coffee with ice. In this case, the coffee will be diluted, so double the amount of beans (or half the amount of hot water) to extract a stronger coffee.
When you want to drink later
If you have time before drinking, brew hot coffee in the same quantity as usual. Take off the heat as it is, and when it cools down to a certain degree, refrigerate it.
Routine care
The key to cleaning the ceramic filter is to remove small coffee beans from the fine spaces in the filter.
We also recommend that you clean the filter as soon as possible after brewing in order to prevent from discoloration of the filter (special care will restore the color of the filter as we will show you later, but it is more effective to clean the filter as soon as the coffee is finished brewing in order to remove the coffee fines).
You can simply rinse the filter with tap water, but here we will show you how to carefully clean the filter, which takes about 3-4 minutes. This method will keep the filter in good condition without the need for special care.
Step 1: Discard coffee grounds in the filter.
Fill the coffee filter with tap water and dump the coffee grounds into something. Then roughly rinse the filter with tap water that is coming out as vigorously as possible.
Step 2 Gently submerge the filter in a container filled with water.
Slowly submerge the filter in a container of water (e.g., a saucepan) and allow the water to enter in the filter from the bottom. Repeat 3 or 4 times, then discard the water in the container.
Step 3 Place the filter upside down and slowly pour hot water over it in the drip pot.
Place the filter upside down in the container and slowly pour the hot water remaining in the drip pot over the filter. (This allows the hot water to flow back through the filter, removing additional fines.) (To perform this care procedure, boil more water when brewing coffee and leave extra hot water.) When you have finished pouring hot water, add water to the container to prevent burns, lower the temperature of the water, and repeat the same operation as in 2 about 10 times. Then, discard the hot water.
Step 4 Fill the container with water again and submerge again.
Repeat the same operation as in step 2 about 10 more times. (It is important to remove the fines from the bottom of the filter, so only about half the water is needed to fill the filter.) When finished, discard the water in the container.
Step 5 Re-fill with water and store the filter submerged in the container.
Rinse the filter again under running water, submerge it in a container filled with fresh water, and store it. (If the filter is not used for more than two days, replace the container with fresh tap water once a day.)

Special Care
When the extraction speed is slowing down
If you wash the pot immediately after use and soak it in water, the extraction speed is less likely to slow down. If the extraction speed becomes slow (as a rough guide, 300 cc cannot be extracted within 5 minutes), boiling the pot for 5 to 10 minutes will restore the extraction speed.
When boiling, place the filter on the bottom of the pot like this (the bottom of the filter is shaped so that dirt can be easily removed by boiling. (The bottom of the filter is shaped to easily clean off dirt during boiling, and the flat bottom of the filter is designed to be stable during boiling.)
Boiling is fine with water, but adding a little baking soda will make the stain easier to remove.
If you still feel that the extraction speed has not returned, please try the following method.
|
1. Spray the inside of the filter with a thicker concentration of dish bleaching agent. |
If you are concerned about the dirt in the filter
If washed immediately, the stain will most likely come off, but if you are concerned about stains on the white ceramic filter, add chlorine or oxygen bleach (such as dish bleaching agent) to hot water of 40°C(104.0 °F) or higher in a slightly thicker solution and leave it in the water for about half a day to clean it.
After dipping it in dish bleaching agent, please boil it in water (or boil it in water with baking soda) as described earlier.
Cautions for use
✔︎ This product can be used for water, alcoholic beverages, and tea, but we recommend that you use one filter for one purpose, as strong flavored products may transfer their smell and taste.
✔︎ This product is ceramic. It will not break with a light impact, but like most ceramic plates and cups, it will break if subjected to a strong impact.
Frequently Asked Questions
Q. Is it OK to use the product before it is dry after washing?
A. Yes, you may use it before it is dry after washing.
After use, you may leave it soaking in water (that way, it is less likely to get dirty), and there is no problem if you keep it in water until the next use.
When using a wet filter, there is a possibility that the coffee temperature will drop due to the water inside.
Therefore, we recommend that you drain the water or, drain the filter lightly after removing it from the water, add the ground beans and warm the entire filter in a microwave oven at 500 watts for 1 minute before brewing as usual. Microwaving makes even old beans look like freshly roasted beans, and the coffee tastes better.
This is a matter of personal preference, so we hope you will enjoy it any way you like.
In any case, since there is still water in the filter, we recommend that you use less hot water than usual when brewing, so that you can enjoy your coffee at its usual strength.
Q. What should I keep in mind if I want to store the product for a long time?
A. For long-term storage, boil the product once and dry it thoroughly (you can use a dryer).
As long as it is dry enough, you can store it as is.
Q. Can't I use fine ground coffee beans?
A. In general, all manufacturers' ceramic filters recommend using a medium to coarse grind. Finely ground beans can also be used for extraction, but are not recommended because they tend to slow down the extraction speed during use.
Q. How often is special care needed?
A. As an example of use, I have brewed coffee over 100 times using this method and have never had to do any special care, yet it maintains this appearance and extraction speed.
（addition.１）How to brew even better hot coffee
For those of you who want to know more about how to make a good cup of coffee, we have put together a list of the best coffee brewing methods 😊.
We hope you will find it useful when you have time.
The method of brewing delicious coffee shown here is an example of the best way to brew delicious coffee for ceramic filters, which we have arrived at through repeated trials using the ceramic coffee filters we sell, with reference to the coffee brewing methods introduced by various people in articles, videos, books, etc. on the web. This is an example of the best way to brew a good cup of coffee for ceramic filters. In particular, we have incorporated many of the contents from the following books.
(Reference book: World Barista Champion Teaches You How to Brew the World's Best Coffee by Hidenori Izaki, published by Diamond Inc.)
Three essential points for brewing good coffee
The taste of coffee varies, of course, depending on the beans you buy, but even if you buy the same beans, the taste and aroma can vary so much depending on how they are brewed that it is hard to believe that they are the same beans.
There are three essential points to brewing a good cup of coffee.
|
Point.1 Keep beans fresh.
|
point.1 Keep beans fresh
Coffee beans are said to be perishable.
The beans begin to deteriorate as soon as they are roasted, so the sooner they are roasted and brewed as soon as possible, the better they will taste. When stored, the rate of deterioration should be slowed down as much as possible. To do this, the following two points should be considered.
(1) Buy beans in bean form and grind them to powder just before brewing.
(2) Store the beans at the lowest possible temperature (freezer is best).
The reason for (1) is that ground beans deteriorate faster. The reason for (2) is that the lower the temperature, the slower the deterioration. If you buy beans, you will need a grinder (mill) to grind them, but if the grinder is not good enough, the ground powder will not be in good condition, and the taste of the coffee will be considerably adversely affected. If you do not have a good grinder, it is often better to buy the coffee in powder form and drink it as soon as possible. (If you are purchasing a grinder, a hand-ground grinder with stainless steel teeth is recommended in terms of cost performance. )
point.2 Keep the ratio of the beans and hot water constant at all times
The sense of concentration in coffee has a great impact on the taste. If you know the ratio of beans and hot water that tastes good to you, you will always be able to brew it at that state. To do this, you need to use a kitchen scale to weigh and brew.
Generally speaking, the best ratio is 15 to 16 hot water to 1 bean, so if we adopt a ratio of 1:15, for example, for 10 grams of beans, we should pour 150 grams of hot water, and for 20 grams of beans, we should pour 300 grams of hot water.
point.3 Care the tempature of the hot water and pour hot water in a good extraction speed.
If the time required for extraction is too short, the flavor and aroma will not be fully extracted. On the other hand, if the time is too long, components that adversely affect the taste, such as miscellaneous flavors, are more likely to be extracted.
Also, if the temperature of the hot water is too high, it tends to increase the amount of impurities, and if it is too low, it tends to be un-extracted. Although it depends on the degree of roasting of the beans, the recommended temperature is generally between 90-93℃. (194°F-199.4°F)
(This is roughly the temperature you get when you pour boiling water into a drip pot.)
) The ceramic filter will drain hot water more quickly than a paper filter. Also, the oils and other substances in the coffee will be extracted more easily than with a paper filter. (The difference in the amount of oil is obvious when looking at the surface of the coffee after brewing. Compare once).
) Because the ceramic filter allows hot water to escape at a faster rate, the steeping time should be longer than the 30 seconds generally recommended, about 1 minute being optimal.
How to brew coffee
There is no correct answer that says this is the only way to brew coffee, but as an example, we will show you how to brew a good cup of coffee with a ceramic filter. (Depending on your preference, the taste can be altered by changing the ratio of beans to hot water, the grind when grinding the beans, the temperature of the hot water, the steeping time, the way the water is poured, etc.)
1 How to determine the amount of beans and hot water
Set the hot water to 15 for 1 bean. Specifically.
For 10 g of beans, 150 g of hot water
14g of beans, 210g of hot water
For 20g beans, hot water 300g, etc.
The following explanation is based on the case of 14g of beans.
2 Grind the beans
Weigh 14 g of beans on a kitchen scale and grind them in a grinder. A medium grind is recommended.
3 Set ceramic filter on coffee server
Place the coffee server on the kitchen scale. After allowing tap water (running water) to permeate through the ceramic filter, set it on the coffee server.
4 Pour boiling water into drip pot
Pour the boiling water into the drip pot and allow the water to cool slightly to a temperature of about 90-93°C. (In the summer, the temperature tends to be higher, so you may want to let it sit for a few dozen seconds.)
5 Pour hot water into the ceramic filter
Pour hot water through the ceramic filter to warm the filter and server. Discard the hot water that has accumulated in the server.
6 Put the ground powder into the ceramic filter
Place the ground powder into the ceramic filter. If the surface is not flat, hold the ceramic filter and shake it slightly to flatten the surface. Reset the kitchen scale value to 0.
7 Pour hot water and steam for 1 minute
Pour the hot water while measuring the time with a stopwatch, stop pouring once the hot water has been poured over the entire powder, and wait until one minute has elapsed.
8 Pour hot water for the second and third pitches.
Pour in two or three more pours, pouring the hot water evenly over the entire powder. When the kitchen scale reads 210 g, stop pouring. When all the hot water has been poured out, the process is complete.

~Others~.
There is the method of pouring hot water by pouring 20% of the total volume in the first pitcher, another 20% in the second pitcher, and all the rest in the third pitcher. I have tried this method with a ceramic filter and have found that it brews very well every time, so I will also show you how to do this. (The above method also brews very well, but this method gives a more consistent taste every time.)
1 How to determine the amount of beans and hot water
Make the hot water 15 for 1 bean. When pouring the hot water, the first pitch is 15 x 0.2 = 3, the second pitch is also 3, and the third pitch is the remaining 9 in all. Specifically.
In the case of 10g beans, 30g for the first pitch, 30g for the second pitch, and 90g for the third pitch (total of 150g of hot water)
In the case of 14g beans, 42g for the first pitch, 42g for the second pitch, and 126g for the third pitch (total 210g of hot water)
In the case of 20g beans, 60g for the first pitch, 60g for the second pitch, 180g for the third pitch (total of 300g of hot water), etc.
In the following, the explanation is based on the case of 14g beans.
2-6 are the same as above.
7 Pour hot water and steam for 1 minute
Pour hot water over the entire powder while measuring the time with a stopwatch, stop pouring once it reaches 42g, and wait until one minute has elapsed.
8 Pour hot water for the second and third pitches.
Pour in another 42 g of hot water (the kitchen scale value is 84 g). When the hot water is completely poured out, pour a third pitcher, and stop pouring when the kitchen scale reads 210g. When the hot water is completely poured out, you are done.
（addition.２）How to wash out coffee beans
As for how to wash out coffee beans, we will also show you the washing method our staff uses at home.
The first staff member prepares a tea strainer and a cup or other deep saucer like this
Pour the rinsed contents into a tea strainer.
Place on a saucer to drain water.
To some extent, I use the method of drying it out by opening it into a newspaper trash can after the water runs out.
Another staff member prepared a colander and a cloth to
Cover the colander with a cloth and set
Rinse the contents with water, then drain the colander into a colander.
Squeeze the cloth tightly.
Leave it on the colander as it is, and when it's somewhat dry
Spreading it out makes it easier to dry.
Cloth, such as cotton or linen, is recommended because it dries better. â- If you cut used T-shirts, etc., and make a stock of two or three pieces, you can make a cycle even if you drink coffee every day.
If you want to use it for deodorant, etc., you need to dry it out, so use a cloth to spread it out. If you have a full stock of coffee grounds because you drink it every day, it is eco-friendly and easy if you drain some of it with a tea strainer or newspaper and put it in a compost or similar container.
If you have something similar at home, please use it as a reference ✨.
