Different types of tea have different production methods.

For example:

- Green tea is not fermented and is made by steaming or pan-firing the leaves.

- Black tea is fully fermented and is made by withering, rolling, fermenting, and drying the leaves.

- Oolong tea is partially fermented and is made by withering, rolling, fermenting, and drying the leaves with a specific process that varies depending on the type of oolong.

- White tea is made by withering and drying tea buds or young leaves that have not fully opened.

These are just a few examples, as there are many different types of tea with unique production methods.
