How many of the 5 most feared taboos of storing tea leaves do you know?

On a sunny afternoon, sitting alone in the courtyard, lighting a pottery stove, prying a cake of tea stored in youth, listening to the gurgling of tea, and the fragrance of tea.

This is the meaning of storing tea, and it is also a yearning for life for tea lovers. It has always been popular in the tea circle to store new tea and drink old tea. Especially white tea, the longer it is stored, the more fragrant it is.

Speaking of storing tea, it must be mentioned that tea is also afraid of it. If you have the habit of storing tea, you must remember these 5 points.

Tea is afraid of moisture and moisture prevention.

Tea leaves are loose and porous, contain hydrophilic substances, and have strong hygroscopicity. There is a lot of rain in summer, and tea leaves easily absorb moisture in the air. Be sure to seal the package well and do not let the tea leaves be exposed to the air. If the tea leaves are brittle when pinched, it means that the tea leaves are relatively dry. If it feels a little soft when you pinch it, you should pay attention.

Tea is afraid of high temperature and prevents heat.

When the weather is hot, people will get heatstroke, and so will tea. It is afraid of heat. If tea encounters high temperature, it will also change color and taste. Temperature has a great influence on the oxidation reaction of tea. According to research, for every 10℃ increase in temperature, the browning speed of dry tea and tea soup will accelerate by 3-5 times. In summer, you must be careful not to put tea near the hot window. It is best to put it in a cool place.

Tea is afraid of odor and prevents odor.

Tea has a loose and porous structure. It not only absorbs moisture and oxygen, but also easily absorbs odor. The odor mentioned here, in addition to the odor of the environment, also pay attention to the packaging materials. High temperature will make the tea absorb odor more obviously. When storing tea, it must be isolated from odor and not put it together with things with strong odors.

Tea is afraid of light and sun protection.

People are afraid of light poisoning, and so are tea. Tea is very sensitive to light, especially chlorophyll will be degraded by photocatalysis, and the tea will become dark and brown. Some lipid substances are easily oxidized into some low-molecular substances when exposed to light, and the tea leaves will have a stale taste. In summer, be careful to put tea leaves in a dark place, and do not use transparent glass jars or transparent bags to store tea.

Tea leaves are afraid of oxygen and anti-oxidation. Oxygen, which people cannot live without, is what tea leaves fear the most. Many effective ingredients in tea leaves are easily oxidized, especially tea polyphenols and vitamin C.

Oxygen will make the color of green tea soup turn yellow, the color of black tea soup turn brown, the aroma will decrease, and the fresh smell will be lost.

To store tea, it is necessary to isolate oxygen and seal it well. If conditions permit, put a bag of deoxidizer in the tea leaves, or seal it with a vacuum sealer.
