Yesterday I was chatting with a regular customer on Front Street and asked why he always came all the way to Front Street to drink coffee. After all, the Front Street store is in a relatively remote location, and online Taobao also sells ear-hanging coffee that you can brew at home, so you don’t have to make such a big trip here every day.Just when Front Street was mentally prepared to receive his "sweet voice" and "the coffee is particularly delicious" and a series of compliments, he said: "Because drinking your coffee will not cause insomnia or heart palpitations..."Then he began to ask: "Why do I easily suffer from insomnia and heart palpitations when I drink coffee at other places, but not when I drink coffee at your place? And it seems that drinking American coffee is more likely to cause insomnia than Pour over(V60) coffee? Why is this?"The answer is simple, it is caused by the different caffeine content！Friends like this are typical people who are sensitive to caffeine.，Therefore, when a large amount of caffeine is consumed, insomnia and heart palpitations may occur.The reason why coffee drunk in different coffee shops has different effects is because the caffeine content of these coffees varies! Some are lower and some are higher, which leads to situations where some people will suffer from insomnia after drinking it and some will not. So why does this difference occur?It is affected by many factors, such as the amount of powder, extraction method, bean type, etc. As we all know, caffeine comes from coffeefruit（beans), generally speaking, when more coffee beans are used, the caffeine content of the extracted coffee will be higher. Take American coffee for example. Some cafes use 18g of powder for extraction and concentration, while others use 20g. So the difference in powder amount may bring about differences in caffeine content.
In addition, the extraction method also affects the caffeine content. For example, the same 20g powder is used, but when we use different extraction methods, the caffeine content obtained will be different. For example, if Front Street uses a hand brewing method for extraction, its extraction rate may be 20%, and if it uses an Italian method for extraction, its extraction rate may be 22%. In comparison, the caffeine concentration of Pour over(V60) coffee is lower than that of Italian coffee, so when we drink Pour over(V60) coffee, we are not as likely to suffer from insomnia like American coffee.(This is just an example, there are actually many other influencing factors)。Or they are both used to make espresso, but the first cup uses 92°C water temperature, and the second cup uses 94°C water temperature. Then the caffeine content of the second cup of coffee will most likely be higher than the first cup. Because its extraction efficiency is higher, more caffeine will be dissolved from the coffee beans.Of course, it could also be the coffee beans themselves. Just like various fruits, there are different varieties of coffee, and these different varieties have varying amounts of caffeine. Currently, commercial coffee on the market is mainly divided into two categories:arabicaand robusta.Arabica is the most commonly used variety in coffee shops. It has less caffeine, accounting for about 0.9% to 1.2% of the bean weight. Then it is rich in sugar and abundant oil, which gives the coffee a very rich aroma. Because of this, Arabica is widely favored by major coffee shops.(Arabica on the left, Robusta on the right)Compared with Arabica, Robusta has more caffeine, generally about twice as much as Arabica. Not only that, its amino acids andChlorogenic acidThe content will be higher than that of Arabica. This makes the coffee produced with a very thick texture and flavor, so it is very suitable for use as an instant ingredient or added to blends to enhance the quality and flavor of coffee. The "Front Street Commercial Blend" in the Front Street Bean List is added with 10% Luodou beans to give the coffee a richer flavor and richer oils.If the coffee beans used by the store contain Robusta, then its caffeine content will be higher than that of pure Arabica. But it should be noted that Robusta is not a representative of inferior quality. It has many advantages. However, since this is not an introduction to Robusta, I will not go into details.To sum up, we can know that: the extraction method, the amount of powder, the type of beans used, etc. are the main factors that affect the high or low caffeine content. For people who are highly sensitive to caffeine, it is best to pay attention to the amount of coffee you drink every day. Or, change your coffee intake to decaffeinated coffee. Because the caffeine content of decaffeinated coffee is very low, even if it does not need to be controlled, insomnia and heart palpitations will not easily occur.There are different types of decaf coffee, and the current mainstream is artificial decaffeination. The Front Street Bean List includes Front Street Decaffeinated Coffee from Colombia, which usesSwiss water treatment. Not only is the caffeine in coffee beans well eliminated(Decaffeinated to 3% of original bean content), while retaining a certain flavor. If you are more sensitive to caffeine, then decaf coffee is still worth trying~
