One minute a week, a coffee craftsman teaches you how to make coffee at home

Brewing Part 1

Hello everyone, I am Coffee Craftsman. Let’s continue with the second article based on the previous one. If there are friends who haven’t read it, you can read my previous article!

This lecture is not about coffee techniques, but some details of making hand-brewed coffee! The above are all my own combined experience! I hope you can absorb the knowledge I transmit like a sponge!

First of all, brewing water is very important

Raw water contains many substances, which will affect the extraction flavor, so you must use soft water and make it as clean as possible.

In order to let everyone know the difference in water quality more intuitively, I used three different types of water for testing as follows

1.Tap water 2.Filtered water 3.Spring water

TDS: 174

TDS: 175

TDS: 9

These 3 types of water surprised me a little bit. The quality of tap water and filtered water is very similar. It seems that I need to change the filter.

TDS value 100-500 belongs to general purity

TDS values ​​below 50 are considered highly pure water

The higher the purity, the lower the TDS value.

Water with a low purity value is very clean, and the brewed coffee will be very mellow!

If the purity value is high, then its cleanliness is not very clean. You may taste the taste of iron when boiling it, and the brewed coffee will definitely not taste good. The importance of water quality is also very important when making tea!

If you don’t believe it, you can try it yourself and compare it. Use the one that suits you better!

When brewing, we must pay attention to the height of the water injection, not too high, not too low! Just ensure that the water is injected evenly and at the same height. Why should we pay attention to this? Let's look at the picture below:

You can see that the powder layer beside has collapsed. The reason for this is that I injected water into the edge of the coffee powder, which caused the surrounding layers to be destroyed by water, which would lead to leakage! At the same time, high-position brewing will cause water to be injected into the coffee powder to form a backwash phenomenon, and you will see the coffee powder rolling! Secondary extraction is formed! The extraction rate is increased, which means that the sour taste is particularly heavy and it is particularly difficult to drink! This is one of the reasons why coffee made without paying attention to details is unpalatable!

I believe that after reading these two articles, you will have a certain knowledge of coffee brewing techniques and details! I hope you can make it yourself and give me feedback, so that we can have a chance to communicate! Each article only talks about one or two small key points! It is also to cater to our one minute! Why not use fragmentation to learn what you are interested in?

So how to do it well, I have the following conclusions:

1. Ensure the purity of water (pure water)

2. Good coffee beans (unique aroma)

3. Grinder (grind coffee powder to uniform thickness)

4. Brewing ratio

5. Even water injection

6. Control time

7. (Will modify the brewing plan)

There may be more than seven key points. I will tell you all the details that I know. Some people may say warm the spout of the teapot, warm this and that. I believe everyone knows it as long as they have a little experience in drinking tea. I will not repeat these trivial details!

Well, that’s the end of the manual brewing. The next article will talk about two very lazy coffee equipment, which are much simpler and more convenient to operate than manual brewing! After washing up in the morning, the coffee is ready! Are you curious? hhhh~ Then pay more attention to me.

Recently, I have been learning video production software and SLR photography. The pictures and videos will get better and better in the future. I will pass on knowledge in a better way. Convenience is my biggest motivation! There is also an audio version of the opening remarks at the beginning of the article. I hope you like it! I made it by myself in two days, so there are some minor flaws! The sound effect is better with headphones!

If you like me, follow me, you won't regret it! Everything is original! Support forwarding!

If you want to buy coffee, please contact me! The only skill I have is to roast it myself! I look forward to your support!
