Why is the hand-brewed single coffee that has a faint taste and no aroma? Shallow and deep-roasted coffee brewing parameters!

Friends often report that although the coffee they brewed tasted quite good, it never felt as delicious as it tasted in a coffee shop. The aroma is not so strong and the flavor is not so obvious, so I asked Qianjie how to improve it.

If you use the same coffee bean, and the flavor of the coffee you make yourself is not as strong as that you drink it in the store, it is generally caused by two situations: one is that the concentration is not high enough, and the other is that the extraction is not so sufficient. Low concentration means that the coffee has been fully extracted, but because too much water is used for brewing, the concentration is excessively diluted, so the aroma of the coffee is not so strong and the flavor is not so prominent;

Insufficient extraction means that the flavor substances in the coffee are not fully dissolved. There are many reasons for this situation, all of which are not high enough extraction efficiency. If the extraction efficiency is not high enough, the flavor substances in the coffee cannot be dissolved in sufficient quantities, so the coffee will not be any better in terms of taste, aroma, or taste. Although these two reasons seem to be different, they are essentially due to the failure to use the brewing parameters, which leads to the negative situation of weak aroma and less prominent flavor in the coffee. So if we want to make a cup of delicious coffee with strong aroma and outstanding flavor, then we need to adjust the coffee extraction parameters.

Improvement plans You can first compare whether the coffee you brew is not high enough or the extraction efficiency is insufficient. Different problems require different solutions! Take coffee with insufficient concentration, for example. If you want coffee to have a high enough concentration, then the target we adjust is the powder to water ratio of the coffee. Under the premise of keeping the extraction rate unchanged, the greater the proportion of powder and water we use, the higher the concentration of coffee, and vice versa.

Generally speaking, the ratio of powder and water used to brew coffee on Qianjie is 1:15, which can give the coffee the right concentration! That is, it will not make the coffee taste weak and light, nor will it make the coffee too strong and difficult to swallow. If you use a smaller powder-to-water ratio than this, such as 1:16/1:17, Qianjie will recommend increasing the powder-to-water ratio first, and then judge whether the problem stems from the taste of the coffee based on the powder-to-water ratio;

If there is no problem with the concentration of coffee, then the problem may come from the extraction of coffee. Too low water temperature, too rough grinding, poor stirring, too long extraction time, etc. are all reasons why the extraction efficiency is not high enough and the flavor substances of the coffee cannot be fully dissolved. In this case, we need to correct the extraction parameters. Of course, not all friends have the time to try and error one by one, so if you don't have time to try and error, you can also directly apply Qianjie's brewing parameters, which can ensure that the brewed coffee has sufficient concentration and extraction rate. The presentation of flavor will also be quite outstanding.

Parameter Sharing There are two sets of brewing parameters used by Qianjie, one set is used for brewing medium and light roasted coffee beans. For example, coffee beans with a strong aroma of flowers and fruits, such as Qianjie Ethiopian flower kui, Qianjie Kenyan tomato, Qianjie boundary line Xizhao, etc.

Since this type of coffee beans need to retain the floral aroma and fruity charm, the degree of baking cannot be too deep, so that the expansion of the beans will not be too large and the density will be relatively high. So if we want to fully dissolve the floral and fruity charm of these beans, we need to use parameters with higher extraction efficiency! As follows: the amount of powder used is 15g, the ratio of powder to water is 1:15, the grinding degree is 75%~80% of the sieving rate of No. 20 sieve, the brewing water temperature is 91~93°C, the extraction time is 2 minutes ~2 minutes and 30 seconds, paired with a filter cup V60, and three-stage brewing.

The other set is used for brewing medium and deeply roasted coffee beans. For example, Front Street Blue Mountain No. 1 Coffee, Front Street PWN Gold Mantelin, Front Street Brazilian Yellow Bourbon and other coffee beans with strong chocolate, caramel, and hazelnut roasted flavors.

Because this type of coffee beans are deeply roasted and have a large expansion, hot water can easily dissolve flavor substances, so the extraction efficiency of this set of parameters used will be relatively low to prevent excessive dissolution of the bitter taste of the coffee! As follows: the amount of powder used is 15g, the ratio of powder to water is 1:15, the degree of grinding is 70%~75% of the sieving rate of No. 20 sieve, the brewing water temperature is 86~89°C, the extraction time is 2 minutes, and it is matched with a filter cup Kono, three-stage brewing.

The above is all the content shared by Qianjie this time! What everyone needs to note is that these improvement plans are based on the premise that the coffee beans used are fresh enough. If the coffee beans you are using have passed the taste period for a long time, or because the bag is not sealed properly and leaks air, then even if you brew according to the above parameters, it will be difficult to rush out the coffee with strong aroma. Because the aroma of coffee has long been lost, and what you don't have will be able to rush out no matter how hard you rush it. So in addition to the parameters, you can also pay attention to the taste period of coffee beans and try to use freshly roasted coffee beans ~
