There are several main varieties of tea, each derived from the Camellia sinensis plant. The primary types include green tea, black tea, oolong tea, and white tea. The differences arise from how the leaves are processed after harvesting. For example, green tea is quickly steamed or pan-fired to prevent oxidation, while black tea is fully oxidized, giving it a darker color and stronger flavor. Additionally, there are herbal teas, which are not made from the Camellia sinensis plant but from various herbs, flowers, and fruits. Popular herbal varieties include chamomile, peppermint, and hibiscus. These teas often have unique flavors and potential health benefits, making them a popular choice for many tea drinkers.
