How is tea fermented and what impact does this process have on the flavor and health benefits of the tea?

Tea fermentation is a process where tea leaves are oxidized, not fermented like other foods. This oxidation changes the chemical composition of the leaves, affecting the flavor and health benefits of the tea. The level of oxidation determines the type of tea produced, such as black, green, or oolong. This process can enhance the flavor by creating complex and rich taste profiles. Additionally, oxidation can also increase the presence of antioxidants in the tea, which may provide health benefits such as improved heart health and reduced inflammation.
