How long is the best time to brew hand-brewed coffee? What should I do after 2 minutes of making coffee by hand and not filtering it? How long is it normal to brew coffee by hand?

Many people strictly follow the "Scientific Instant Noodle Method" when making instant noodles. Holding a stopwatch, they soak the instant noodles in boiling water at 100°C for 3 minutes, in order to give the noodles the best taste. When making coffee, we also hold the time for the same purpose, which is to stably brew a delicious cup of coffee. Because for coffee, time is also an important parameter affecting taste. Therefore, friends often ask Xiang Street: "Is there the best time to brew hand-brewed coffee? "

To know the answer to this question, we first need to understand what the impact of time on coffee is. Sharing is often common on the front street. The extraction time of coffee refers to the time when the powder and water come into contact. While other parameters remain unchanged, the length of the extraction time determines the amount of coffee soluble matter dissolved. The longer the extraction time, the more substances will be dissolved, and the shorter the extraction time, the less substances will be dissolved. But if we want to make a good cup of coffee, then neither too little nor too much can be dissolved out of the coffee.

Because when there are few flavor substances dissolved, the coffee is prone to insufficient extraction such as weak taste and thin taste; when there are too many substances dissolved in the coffee, the coffee is prone to bitter, miscellaneous, astringent, and other negative manifestations of excessive extraction. So if we want to make a cup of coffee with a pleasant taste, taste, and taste, then we need to control the extraction of coffee. But just as Qian Jie wrote in "Is it really necessary to clock coffee?" As shared in this article: In addition to time, other parameters such as water temperature, grinding, water volume, and water flow affect the extraction. Therefore, time is not the only factor that determines the taste of coffee. As long as other parameters are properly adjusted, No matter how long or short you brew, you can actually make a delicious cup of coffee.

In other words, as long as your brewing time can be properly matched with other parameters, then this time is the "best time" to brew delicious coffee. Then I believe it is not difficult for friends to find that the most frequent time in front street articles is "2 minutes". This is because the other parameters used by Qianjie and the time of 2 minutes can exactly form an extraction plan for making most of the coffee, so it is the time that most often appears in Qianjie articles, and we can also understand it as the "best extraction time" in this formula.

Taking Qianjie as an example, when Qianjie brewed the lightly roasted coffee beans Qianjie Essi Huakui in the bean list, the water temperature used was 92°C, and the grinding degree of the coffee powder was 80% of the sieving rate of No. 20 sieve., the ratio of powder to water was 1:15, and the brewing method was three-stage. Under such a formula, a pot of coffee with a good concentration and taste can be brewed with a 2-minute extraction time. At the same time, the flavor is also very outstanding, including berries, citrus, floral flowers, and the tail rhyme of oolong tea.

But if the time is less than 2 minutes and 1 minute and 30 seconds, the concentration of the brewed coffee will not be as high, and the taste will not be so balanced and full. Coffee tastes widower, light, and not very rich in flavor; and if the time is much longer than 2 minutes, such as 2 minutes and 40 seconds, then the coffee that comes out may have obvious bitter and miscellaneous flavor. Therefore, comprehensively,"2 minutes" is the best time to use this set of parameters to cook Essi Huakui from Qianjie (there can be a certain error, but try not to be too large, such as more than 20 seconds).

So if everyone uses the traditional three-stage water injection method when making light roast coffee like Qianjie, and then the parameters are the same as Qianjie, then 2 minutes will be a good choice. However, Qianjie does not recommend that everyone stick to this parameter, because the states of coffee beans are different, and the same parameter cannot make all coffee well. Just like when brewing deep-roasted coffee beans, we need to lower the water temperature to prevent over-extraction, for some coffees, such parameters cannot dissolve all the flavor substances we want, such as some denser coffee beans. Then at that time, we will need to adjust the parameters according to the taste of the coffee.

For example, when Qianjie was brewing Qianjie Yejia Shefei Guodin in the bean list, although the Guodin prepared using this set of parameters was delicious, the overall expressiveness was still slightly weaker (implying that it could be better). The reason is that it is lighter and has a higher density, and the flavor substances are not as easy to dissolve as the flower essence, so the brewed coffee will be slightly inferior. So if we want to make out a fuller and stronger fruit tintin, we need to improve the extraction efficiency to dissolve more flavor substances. At this time, there are many options we can choose from, such as increasing the water temperature, adjusting the grinding, strengthening stirring, or extending the extraction time. Choose based on your thoughts.

For example, when you fix the time at 2 minutes, all you need to control are other parameters, such as water temperature and grinding. If you don't plan to fix the time, you can choose to replace the filter bowl or extract in stages to extend the extraction time and improve the extraction rate. Either way, it can improve the extraction efficiency during brewing, increase the dissolved flavor substances, and make the coffee perform better. In other words, there are many solutions, and we don't need to fight hard on a certain parameter, whether time or other parameters. When the taste of the brewed coffee does not match your expectations, we need to adjust it in time according to the taste so that we can better brew a pot of delicious coffee.
