Thermos bottle for tea keeps the drink taste fresh longer
Global consumption of tea, the world's second most consumed drink after water, totaled 6.7-6.8 million tonnes in 2022, a rise of at least 6 percent from 2020, based on industry reports. The beverage is rich in antioxidants called flavonoids which are proven to lower the risk of heart diseases and cancer. Although tea drinking habits vary from country to country, a thermos bottle for tea is often used to keep the drink fresh after brewed. Thanks to its special structure, the product is good at retaining heat for an extended time.
Structure
A thermos bottle for tea consists of two vessels, one placed within the other and joined at the neck. They are made of glass or stainless steel. While the stainless steel makes the thermos bottle lighter than using glass refill, the glass one can keep the heat longer and does not affect the flavor of the drinks.
Main parts of a thermos bottle.
In order to reduce heat conduction or convection, air between the two vessels is sucked out to create a partial-vacuum. The temperature of the tea in storage is kept for an extended period as the vacuum does not conduct heat. Therefore, the vacuum is considered to be one of the most important parts of the thermos bottle.
A thermos bottle is widely used in daily life thanks to its convenience.
The case or the shell of a thermos bottle can vary in sizes and colors. The popular materials of the case are stainless steel and plastic, which have a long lifespan.
Three key factors
In order to make fresh and good tea, please don’t forget to take the following three factors into account: water temperature, the amount of tea and the brewing time.
Water temperature
Brewing tea requires using hot water, but the water temperature can vary depending on the type of tea. Boiling water is only suitable for black and herbal tea since it needs high heat to get the true flavor. Cooler water should be used for delicately flavored varieties such as green tea and oolong tea.
Water that is too hot can give the tea a bitter taste while the delicate flavors could be lost. In contrast, using too cold water can end up with a weak, less flavored cup of tea because the compounds in the tea are not dissolved.
Tea amount
Too much tea can make the drink too bitter, while too little makes the taste too weak to enjoy. An ideal ratio that everyone can try is 8g tea for a 300ml pot, then the amount of tea can be adjusted to suit the taste.
Six different kinds of specialty tea are Green, White, Oolong, Black, Pu'erh and Yellow tea.
Brewing time
The most taboo in making tea is ‘soaking’ tea because it will make the tea bitter and smelly. Like water temperature, each tea will be suitable for a certain brewing time. Black tea, oolong tea can be brewed longer than green tea.
After brewing tea, people can enjoy it for the best taste. Moreover, choosing a thermos bottle for tea to preserve the beverage for a long time is not a bad idea. The advantages of the thermos bottle absolutely outweigh its cost.
