In the world there are about one and a half thousand varieties of tea, which are separated not only by properties, but also by the method of packaging. But why is this happening?
Tea history
In the first centuries of our era, people soaked dried herbs in boiling water, and the resulting broth was given to patients as a medicine. The healing properties of some plants were established experimentally, after which they began to be actively used in medicine of that time.
Until the fifth century, tea was used only for medicinal purposes, but in China, when the Tang Empire was founded, decoctions of herbs began to be drunk as a regular drink. Such an innovation quickly spread around the world and became fashionable. By the eighth century, tea had become a common homemade drink, and people began experimenting with herbs, discovering new types of tea leaves.
Interesting fact: Tea invented in China. According to ancient mythology, it was discovered by Shen-nun, an ancient sage who made a great contribution to the development of medicine and agriculture of the country. However, he may be a fictional character, as judging by the description of myths, he had a body of a snake with a human head.
In the 9th century, the seeds of Chinese herbs used to make tea were brought to Japan, where the drink quickly gained popularity. The Japanese served it to the table during the holidays, and then began to use it for ordinary drinking.
Tea appeared in other countries only in the 17th century.The Portuguese, the British and the Dutch drove him from Europe to Europe and America. Famous Indian plantations appeared in the second half of the 19th century. In about three centuries, tea has spread throughout the world and has become one of the most popular drinks.
Tea appeared in Russia in the 17th century, but due to the lack of its own production, it has long remained an expensive product. Only in the 1970s did the first plantations appear in the Krasnodar Territory.
How to make tea bags?
The procedure for preparing this type is quite simple. The dried leaves of the plants from which tea is prepared are crushed to fine crumbs or dust, and then poured into filter paper. Due to its properties, paper does not tear in water, but passes liquid through itself, due to which the brewing process takes place.
Having discovered tea for themselves, people quickly began to put it in specially made bags, previously grinded. Even then, it was noticed that this way it is better brewed.
Interesting fact: Some people used plain paper instead of paper, which also passes water well through itself, but retains ground tea leaves.
Now there are many types of tea that are made in bags. However, in the past this method was applied only to green and black varieties. Over time, people began to grind any varieties.
Why is tea bag brewing faster?
Any objects consist of molecules that mutually attract each other and are in constant motion.The stronger the bond between them, the harder the object is, and the higher the temperature, the greater the amplitude of the movement of the molecules. The same goes for liquids.
Water molecules are constantly moving and interacting in every way with the objects that are in it. When tea leaves are lowered into the water, the molecules envelop them and begin to “bombard”. Because of this, the dissolution process begins, during which tiny particles of tea are distributed throughout the volume, and the brewing process takes place.
Moreover, the higher the temperature of the water, the more actively its molecules move and spread the tea leaves in space faster. If you brew tea in cold water, the process will be much longer.
Tea bags are much smaller than leaf tea, so they have a larger surface area. Because of this, more collisions occur over a single period of time than with large leaves. Accordingly, tea is brewed faster.
Tea in bags is brewed faster than leaf tea due to the fact that the crushed particles interact better with moving hot water molecules, since they have a larger surface area. The stronger the tea is ground, the faster it will be prepared.
