When drinking Pu'er tea, we may wonder why Pu'er tea cakes are compressed. Perhaps the first thought is for convenient storage and transportation, but there are more benefits to compressing Pu'er tea into cakes than loose tea.

First
When Pu'er tea is compressed into cakes, the impact of moisture absorption and evaporation is minimal, thus microorganisms and aromas are better preserved.
Second
When Pu'er tea is compressed into cakes, the internal influence of air temperature on the compressed tea is minimal, allowing the microorganisms in the tea to survive better.
Third
The contact area of oxygen and light with compressed Pu'er tea is greatly reduced, slowing down the oxidation of polyphenols, ketones, and chlorophyll, thereby better preserving the tea's quality.
Of course, the later transformation of Pu'er tea still relies on the quality of the tea leaves themselves. Only when the raw tea material is of guaranteed quality, combined with excellent processing techniques and compression into cakes, can high-quality aged Pu'er tea be produced.
