2. Ingredients to make tea
More than two-thirds of the world's population drinks tea, which is a beverage made from the leaves of a plant scientifically known as Camellia sinensis. The easiest way to make tea is to steep tea leaves in hot water for a few minutes, then you can drink hot tea or drink iced tea.
3. What is the difference between green tea, black tea, and oolong tea?
Tea producers will dry and grind the tea leaves to remove the essential oil, and then can continue to dry them, depending on the type of tea they want to produce. This process is called tea fermentation, which is a chemical reaction that affects the flavor of tea and causes the leaves to turn brown.
The longer the exposure time, the higher the caffeine concentration will be. Green tea means that the tea leaves have not undergone fermentation at all, so green tea has almost no caffeine. Black tea is the type of tea that undergoes the longest fermentation, while oolong tea has a shorter fermentation time than black tea.
