Espresso scale-how much caffeine in a cup of espresso

Students who have done classic experiments in organic chemistry know that caffeine sublimation must first remove water, because water will affect caffeine sublimation. As for coffee beans, can deep baking remove all the water? Obviously not, this in the limited time of baking, will further affect caffeine sublimation.

Caffeine sublimation in the roaster is somewhat similar to the solvent-free direct sublimation method in the laboratory, but with the addition of a catalyst in the laboratory, can the rate of two hours be 50%? If you don't add a catalyst, how much can an extra few minutes of deep baking do? It is much easier to sublimate the broken tea used in the laboratory.

How does the caffeine content change when using different beans?

The previous comparison is the comparison of caffeine content in different extraction methods of the same kind of beans. What about using different coffee beans?

In fact, if you use the same amount of beans, the caffeine content of ESP is often higher than that of hand flushing.

Because Luodou is rarely used in hand flushing, and Luodou is often used in matching beans. As we all know, the caffeine content of the same amount of Luodou is much higher than that of Adou.

The false impression of espresso = high caffeine seems to have taken root in everyone's mind. In fact, the real espresso beans are usually roasted deeply for a long time, and there is not much caffeine left. As for the remaining little caffeine, it must be extracted for a long time before it can be dissolved.

In addition to its unparalleled aroma, consistency and rhyme, Espresso coffee has one of its biggest features: low caffeine. When some people drink Esprsso coffee for the first time, they have the illusion that such strong and pure coffee must have a high caffeine content. In fact, on the contrary, of all the coffee-making methods, coffee is made with the same beans, and the coffee made by the Espresso machine contains the least caffeine. Because the caffeine in coffee is a water-soluble substance, the longer the coffee powder is in contact with water, the more caffeine is dissolved, while the brewing time of Espresso coffee is only more than 20 seconds. When the caffeine is not released, a cup of mellow coffee has already been brewed, so the caffeine content is only 1max, 3mer, 1max, which is generally used in other brewing methods.
