Puerh tea is a type of tea that has undergone a fermentation process, also known as ripe tea or cooked puerh tea. Raw Pu-erh tea, on the other hand, is a tea that has not undergone fermentation treatment, also known as green Pu-erh tea.

The differences are as follows:

1. Appearance and color: Pu-erh tea is darker in color, full of tea leaves, and has an obvious taste of aging, while raw Pu-erh tea is lighter in color, with an irregular tea leaf pattern, and no obvious taste of aging.

2. Production process: Pu-erh tea is processed through a number of processes, such as fermentation, stacking and ripening, while raw Pu-erh tea is only processed after picking and does not require fermentation and pressing.

3. Flavor and texture: Pu-erh tea has a mellow and refreshing, aged flavor with a smooth, sweet and mellow texture. While raw Pu'er tea is fresh and crisp with a light flavor.

4. Aging time: Pu-erh tea is quite suitable for aging, especially the more aging, the more fragrant, the more aging flavor, while raw Pu-erh tea is not suitable for long-term aging, usually the newer the better.

5. Value: Pu-erh tea is relatively expensive because of its classic craftsmanship, hundreds of years of history and health benefits. And the price of raw Puerh tea is relatively low.
