Many people will strictly follow the "scientific noodle soaking method" when making instant noodles. They hold a stopwatch and soak the instant noodles in 100°C boiling water for 3 minutes. The purpose is to give the noodles the best taste.And when we brew coffee, we also hold on to the time. The purpose is the same, which is to be able tostableMake a delicious cup of coffee. Because for coffee, time is also an important parameter that affects the taste. So friends often ask Front Street Street: "Is there an optimal brewing time for Pour over(V60) coffee?"To know the answer to this question, we first need to understand the impact of time on coffee.It is often shared on the front street that the extraction time of coffee refers to the time when the powder and water are in contact. When other parameters remain unchanged, the length of extraction time determines the amount of coffee solubles dissolved. The longer the extraction time, the more substances are dissolved, and the shorter the extraction time, the less substances are dissolved. But if we want to make a good cup of coffee, we can neither have too little nor too much of what is dissolved in the coffee.Because when there are less dissolved flavor substances, the coffee is prone to be under-extracted, such as bland taste and thin mouthfeel; and when there are too many dissolved substances, the coffee is prone to be bitter, miscellaneous, astringent, and other negative manifestations of over-extraction. So if we want to brew a cup of coffee with a pleasing texture and taste, then we need to control the extraction of coffee.But just as the front street is"Is it really necessary to time your coffee?" 》As shared in this article: In addition to time, other parameters such as water temperature, grinding, water volume, and flow rate also affect extraction. Therefore, time is not the only factor that determines the taste of coffee. As long as the other parameters are properly adjusted, no matter how long or short your brewing time is, you can actually brew 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 time that appears most frequently in Front Street articles is "2 minutes." This is because the other parameters used by Front Street and the time of 2 minutes can exactly form an extraction plan for brewing most coffee, so it is the time that appears most often in Front Street’s articles. We can also understand it as the “optimal extraction time” in this formula.Taking Front Street as an example, when Front Street brews Front Street Esai Oiran, the light roasted coffee beans in the bean list, the water temperature used is 92°C, the grinding degree of the coffee powder is 80% of the No. 20 sieve, the powder to water ratio is 1:15, and the brewing method isthree-stage. Under such a formula, with an extraction time of 2 minutes, a pot of coffee with quite good concentration and taste can be brewed. At the same time, the flavor performance is also very outstanding, with berry, citrus, floral, and the aftertaste of oolong tea.
But if the time is less than 2 minutes, at 1 minute and 30 seconds, the concentration of the coffee brewed will not be that high, and the taste will not be so balanced and full. The coffee tastes dull, light, and not very rich in flavor; and if the time is much longer than 2 minutes, for example, 2 minutes and 40 seconds, the brewed coffee may have obvious bitter and mixed flavors. So overall, "2 minutes" is the best time to brew Front Street Esai Oiran using this set of parameters.(There can be a certain error, but try not to make it too large, such as more than 20 seconds)。So if you are like Front Street and use the traditional three-stage water injection method when brewing light-roasted coffee, and the parameters are consistent with Front Street, then 2 minutes will be a better choice.However, Front Street does not recommend that you stick to these parameters, because the status of coffee beans is different, and the same parameters cannot brew all coffees well. Just like when brewing dark roasted coffee beans, we need to lower the water temperature to prevent over-extraction. For some coffees, such parameters are not able to dissolve all the flavor substances we want, such as some coffee beans with higher density. Then, we will need to adjust the parameters according to the taste of the coffee.For example, Front Street is in the brewing bean list.Yirgacheffe GudingdingWhen using this set of parameters, although the diced fruit tastes delicious, the overall expressiveness is still slightly weaker.(The implication is that it can taste better), the reason is because its roasting is lighter, the density is higher, and the flavor substances are not as easy to dissolve as Oiran, so the coffee brewed will be slightly inferior.If we want to produce fruit dices with fuller and more intense flavor, we need to improve the extraction efficiency to dissolve more flavor substances. At this time, we have many options to choose from, such as increasing the water temperature, finer grinding, strengthening stirring, or extending the extraction time. Make your choice based on your ideas.For example, when you fix the time at 2 minutes, what you need to control are other parameters, such as water temperature and grinding. And if you don’t plan to fix the time, you can choose to replace the filter cup or perform segmented extraction to extend the extraction time and improve the extraction rate. No matter which one, 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 do not need to stick to a certain parameter, whether it is time or other parameters. When the taste of the brewed coffee does not meet your expectations, we need to make adjustments according to the taste in time, so that we can better brew a delicious pot of coffee.
