Coffee is almost an irreplaceable partner for modern people in the morning. Without caffeine, the body seems to be in sleep mode. But what about the caffeine content of deep-roasted coffee beans? Or is the caffeine content of light roasted coffee beans better? Let's take a look at the Tasting Table report.

No matter who goes through a sleepless night or a severe mental deficiency, they all know the whole process of drinking that too strong black coffee to wake up from the stomach to the brain. Similarly, people intuitively think that there is more caffeine in deep-roasted coffee, right?

This is a long-debated issue in the coffee industry. While many people believe that deep-roasted coffee is full-bodied and of course there will be more caffeine, others believe that light roasting is a better choice when you need a lot of caffeine to wake up. However, can you believe it? both sides are wrong.

In fact, every coffee bean has the same caffeine content, whether it's deep roasted or light roasted.

So why is there a long-standing rumor that light-roasted coffee has the ability to retain caffeine?

Proponents of light-roasted coffee believe that the longer the beans are roasted, the more caffeine volatilizes in the beans, but in fact, the longer the beans are roasted, the less caffeine is, but the more water is lost.

Coffee beans also swell slightly during roasting, making deep-roasted coffee beans larger and lighter than shallow roasting.

So the conclusion is that the same amount of coffee you drink every morning contains more shallow roasted beans, so the coffee is relatively strong. However, according to the experience of many professional bakers, a little more is negligible.

What is the most important inspiration of this story? The most correct way to treat mental insufficiency is to get more sleep.

At the same time, related studies have found that caffeine in coffee beans does not volatilize until it reaches more than 600 degrees. However, whether it is deep roasting or light roasting, the maximum roasting process is only about 220 degrees, and the volatilization is water or other substances. From this point of view, the caffeine content of the two kinds of coffee beans is the same.

However, in the process of making coffee, shallow roasted coffee beans have more water content, so making coffee of the same capacity requires less coffee beans and lower natural caffeine.

And many light-roasted coffee beans choose high-altitude coffee beans of better quality, and these coffee beans from high-altitude areas have relatively less caffeine. This may be one of the reasons why many people think that deep-roasted coffee has a better refreshing effect when it comes to coffee.
