As the name implies, tea leaves are sealed and soaked in cold water or ice water for 4-8 hours to obtain tea, which is suitable for relieving summer heat and quenching thirst. When you are hot and thirsty, you can gulp it, and you can taste the fragrance of tea without sipping it slowly like hot tea.
What is the difference between tea and hot water?
1. sweetness: cold water can dissolve the sweet amino acids in tea, while bitter tannins and caffeine that need hot water to be dissolved are firmly locked in tea, so the cold-soaked tea tastes almost bitter, leaving only cold and sweet.
2. Enjoy at any time: unlike making tea with hot water, you need to master factors such as water temperature and time. In Taiwan Province Province, the birthplace of cold-soaked tea, people just throw in a bottle of iced mineral water and a tea bag when they go out to play or exercise, even if their hands are broken, and then they can drink sweet cold-soaked tea.
3. You can soak for a long time: office workers and student parties need to concentrate in class. After the tea is brewed, they often forget it. As soon as they thought about it, the tea was already very strong and bitter. Cold soaking tea is not so troublesome. It can be drunk within 8 hours after soaking. Cold water can alleviate the bitterness of tannic acid and caffeine, and it will not be bitter after soaking for a long time.
4. Does not affect sleep: Because the caffeine content in cold-soaked tea is less, it will not affect sleep even if you drink it before going to bed.
In a word, the biggest difference between cold-soaked tea and hot tea is the difference in tannic acid and caffeine content.
Having said that, what should I do?
1. Material preparation: a sealed bottle or jar, tea leaves, tea bags and ice water.
Tea can be used except Pu 'er tea, among which green tea is the most fragrant and sweet, and all kinds of herbal tea are also a good choice.
I used green tea and osmanthus this time. The combination of tea fragrance and floral fragrance can make people feel good all day!
2. Wrap the tea leaves in a tea bag (in fact, it doesn't matter if you don't use it, that is, the color and taste of the soup will be slower), pour in ice water, put in the tea bag and seal the bottle.
3. Leave it at room temperature for about 40 minutes or put it in the refrigerator for 4 hours, and the tea color and taste will be fully released. At this time, add ice cubes and honey and enjoy the cool afternoon tea on a hot summer day!
