Drinks include coffee, tea, green tea and caffeine, which you are used to every day. Did you know that the content of caffeine varies with the way it is made? Today, "caffeine content" we will talk about tea and coffee.

About caffeine content

The content of caffeine varies from variety to variety. In the case of coffee, Robusta is said to be better than Arabica coffee, using bean sprouts in the case of tea and caffeine in Gyokuro in the case of green tea. In addition, it varies according to the environment, roasting and extraction methods of the production area.

In the case of tea

Tea has more caffeine than coffee. However, because a small number of leaves of tea are used for cup by cup, which is the state of extraction, there is less caffeine than coffee. It is said that the tea to be extracted is powdered, or if the tea is soaked in hot water for a long time, it is said that the content of liquid caffeine will increase, so be careful.

How to cook tea

In order to reduce the caffeine content of black tea, it is important not to soak the tea in hot water for a long time. After soaking for a long time, the caffeine in the tea dissolves stably, so we should pay attention to the extraction time. It is safe to avoid boiling black tea as much as possible.

Because of the differences between varieties, Assam makes a lot of caffeine content when brewing is boiled in hot water, preferably extracted at a little bit of lukewarm temperature. Darjeeling is said to increase the amount of caffeine when drinking water, so let's have a drink of what you extract with hot water.

For coffee

Coffee, caffeine content changes through roasting. Are there more images of caffeine and deep roasting?

Because caffeine is decomposed by roasted calories, deep-roasted coffee beans and mixtures have less caffeine. If you like light roasted coffee, please be careful to drink too much.

How to order coffee

Just like coffee and black tea, you can reduce caffeine content by extracting it at a lower hot water temperature or quickly. The recommended method for short convection time of hot water is a French press. Compared with dripping coffee, caffeine content is lower because the coffee powder is soaked in hot water for a shorter time.

It is a trick to open the cup quickly after extraction. Moreover, because the extraction time of espresso is short, the content can be reduced. In both cases, it is important to use deep-roasted coffee with low caffeine content.

What is the caffeine content of instant coffee?

For instant coffee, robusta seeds are often used as raw materials, so it's easy, but drinking a lot of caffeine is not recommended.

If you drink instant coffee or drink hot water diluted to American style, drinking less coffee from caffeine can allay the worry about caffeine content.

Drink too much attention? The caffeine content was determined by beer method.

The content of caffeine depends on the variety, baking and extraction methods.

In the case of black tea, caffeine is contained in many sprouts, so people who like to flash quickly need to be cautious. In addition, tea in the form of extract and powder, you are immersed in hot water for time will increase in the long term and caffeine content. For coffee, coffee beans contain a small amount of roasted, shallowly roasted beans, with more caffeine.
