What type of tea is often aged to enhance its flavor?

Post-fermented tea is unique in that it undergoes a fermentation process that allows it to age, which enhances its flavor profile over time. This type of tea, notably represented by Pu-erh tea, is carefully processed and then allowed to mature, resulting in complex flavors that develop as the tea ages. The aging process can lead to a smoother taste, with earthy and rich notes that are sought after by tea enthusiasts.

In contrast, green tea is typically consumed fresh and has a more delicate flavor, black tea is fully oxidized and does not usually undergo aging, while white tea is the least processed and is also intended to be enjoyed fresh for its subtle flavors. These teas do not have the same aging process that characterizes post-fermented tea, making the latter the only one among the options that benefits from aging to enhance its flavor.
