Betel-nut aroma is a traditional and highly characteristic sensory descriptor for Liu Bao tea, particularly in well-made and appropriately aged examples, but it should not be interpreted as meaning every Liu Bao must literally taste like chewing betel nut.
Liu Bao can naturally taste earthy, woody, mushroom-like, medicinal, or reminiscent of forest floor, but a clean earthy character is very different from a stale, moldy, sour, or rotten mustiness caused by poor processing or storage.
Pu-erh tea can potentially be stored for decades or longer, but there is no fixed maximum aging period and no guarantee that an older tea will be better. The realistic lifespan of Pu-erh depends on the original material, processing, compression, storage environment, and the condition of the tea over time.
Pu-erh tea can change dramatically during aging, particularly raw Pu-erh. Over time, its aroma, color, bitterness, astringency, sweetness, texture, and aftertaste may evolve as the tea interacts with its storage environment. However, aging is not a guarantee of improvement: the quality of the original tea and the quality of storage determine whether aging produces desirable results.
Pu-erh is compressed into cakes, bricks, and tuos primarily because compression historically made tea easier to transport and store, while also becoming an important part of Pu-erh's production and aging tradition. Compression can affect aging behavior, but it does not automatically indicate higher quality.
White tea can taste bland because the leaf-to-water ratio is too low, the water is too cool, the infusion is too short, the tea is stale, or the tea's naturally delicate character is being mistaken for weak extraction.
White tea is often misunderstood because its reputation for delicacy can lead people to under-brew it.
