Black coffee refers to pure coffee without any additives such as sugar or milk. For example, the common hand-brewed coffee, American coffee and espresso coffee in the fine coffee market belong to black coffee. Among them, the most important problem is that black coffee is coffee without any modification. Does it mean that coffee will be more mellow and caffeine content will be higher? Especially like espresso coffee, the proportion of water is small, then the next article front street coffee to answer for you espresso coffee and black coffee caffeine content is how much.

What is caffeine?

First of all, we should know what caffeine is. It is well known that caffeine has a certain exciting effect on the central nervous system and temporarily restores certain physical strength, so it is loved by many office workers. Caffeine is actually an alkaloid. In hot cocoa, functional drinks, cola, coffee tea and other natural drinks, it will contain a certain amount of caffeine. Even in nature, most plants contain this substance.

Caffeine is a central nervous system stimulant and a metabolic stimulant. Caffeine is also used as a drug to refresh and relieve fatigue. The exact amount of caffeine needed to produce an effect varies from person to person, depending on body type and caffeine tolerance.

But everyone also knows that medicine is three points toxic, natural caffeine is also not excessive intake, otherwise it will affect health, and may cause excessive excitement, and black coffee is pure coffee bean extract liquid, does that mean it has higher caffeine content?

Caffeine content of black coffee

According to Qianjie Coffee, the caffeine content of black coffee is also related to the variety of coffee beans. At present, the most common coffee varieties on the market are Arabica and Robusta. The caffeine content of Arabica is lower than that of Robusta, and the flavor is better. Therefore, it is used by all major coffee beans to make hand-brewed coffee. For example, the coffee bean varieties of fine hand-brewed coffee in Qianjie Coffee Shop are all derived from Arabica coffee beans.

Robusta, for example, has more than twice the caffeine content of Arabica and does not measure up to the standard of fine coffee (fine coffee cup score of 80 and above), so Robusta beans are not used for hand coffee, but are widely used as instant coffee or espresso blend beans.

According to Qianjie Coffee, the caffeine content of black coffee is mainly related to coffee varieties, while Arabica caffeine content is 0.9~1.2% and Robusta caffeine content is 1.6~2.4%.

How much caffeine does a cup of black coffee contain? The following is the answer to everyone's question:

For example, a cup of hand-brewed coffee has 225 ml, the ratio of coffee powder to water is 1:15, that is, the number of grams of coffee used is 15g, and the coffee variety is Arabica, that is, the caffeine content of a cup of hand-brewed black coffee is 0.9~1.2x15g=135~180 mg.

How much caffeine does an espresso contain?

These two coffee beans are Arabica derived varieties, so their caffeine content is also 0.9~1.2%.

The milliliters of espresso coffee supplied by each coffee shop are also different, so the caffeine is also different. For example, the espresso coffee produced by the former street coffee is 40 ml. Because it is extracted by the espresso machine, the proportion of water powder will be different from that of hand-brewed coffee. The ratio of espresso powder to water produced by the former street coffee is 1:2. The coffee powder used in producing a cup of 40 ml espresso coffee is 20g, which can be obtained. The caffeine content of a cup of espresso coffee is 0.9~1.2x20g=180~240mg.

The above is the answer to the caffeine content of a cup of espresso and a cup of black coffee compiled by Front Street Coffee. How much caffeine can the human body consume in a day?
