Milk tea is more refreshing than coffee, it turns out it’s due to the different extraction methods!

Every time I go to a mall, there is always this kind of shop, where the queue is three layers deep inside and three layers deep outside, and it goes around 18 corners. There are also many brands. Yes, that's right, it's a milk tea shop! Whenever this happens, Brother Rong really wants to have a cup of bubble milk tea, silk stocking milk tea, or panda milk cap. It's so tempting!

However, every afternoon after drinking milk tea will usher in a late night of thinking about life. In order to explore the relationship between drinking milk tea and insomnia, I tried all the milk teas in the mall next door at once, and the results showed that the insomnia effect was quite good! Of course, I was joking. I tried it and lost all the weight I had lost in the past few months.

The Shenzhen Guangming District Consumer Committee tested ten brands of milk tea, including the well-known brands: X雪の茶, 可, X点点, 米X莲, etc. The test showed that each milk tea contained caffeine, with an average content of 258 mg per kilogram.

Among them, Michelin's classic silk stocking milk tea has the highest caffeine content, 522 mg per kilogram. A large cup of silk stocking milk tea has about 365 mg of caffeine, which is equivalent to drinking 7 cans of Red Bull! No wonder you will suffer from insomnia after drinking silk stocking milk tea!

How can milk tea be so powerful? If you drink a few more pots of tea at home, you won't stay awake all night. Besides, this milk tea shop is a business, how much tea can they afford to put in it? Well, you really don't understand milk tea.

Let's talk about drinking tea at home. First of all, the caffeine content in coffee beans is about 1% of its mass, while the caffeine content in tea leaves is 2%~3% of its mass. Although the caffeine content in tea leaves is higher than that in coffee beans, when we compare the caffeine content of a cup of tea and a cup of coffee, it makes no sense to use dry tea, it has to be brewed.

The Specialty Coffee Association of America recommends a coffee brewing ratio of 8.25 grams of coffee beans for every 150 milliliters of water. However, the tea bags on the market used for single brewing generally contain only about 2 grams of dry tea. This shows that the caffeine content of a cup of coffee is much greater than that of a cup of tea.

However, the different extraction methods of tea and coffee in the process of changing from solid to beverage will lead to different caffeine concentrations. When tea is used in the milk tea industry, multiple and long-term extraction and concentration will cause the caffeine content to soar sharply. Therefore, the milk tea sold in milk tea shops may only have a little more tea than usual, but the caffeine content has increased many times.

A while ago, Rong Ge and his friends went to listen to a crosstalk. They drank a pot of jasmine tea from 7:30 to 10 o'clock, and then watched the moonlight flow and the east was already bright. Taking caffeine before going to bed will have a more obvious impact on sleep, especially for those with sensitive constitutions. Once it's past the afternoon, you still firmly say no to foods containing caffeine!
