In addition to distinguishing tea plants by leaf size. The study also found that there are actually differences in the proportion of grid-like tissue and sponge tissue between large and small leaf species, which directly affects the performance of large and small leaf species in taste and taste. The leaf flesh of the large-leaf species has a single layer of grid-like tissue, while the small-leaf species tea plant has 2-3 layers of grid-like tissue, so visually the leaf surface of the small-leaf species is generally dark green from the larger leaf species.
On the ratio of sponge tissue to grid-like tissue. The sponge tissue of the large leaf species is 2-3 times that of the grid-like tissue, while the ratio of the sponge tissue of the small-leaf species to the grid-like tissue is about 1:1. However, the liquid cells that store tea flavor substances are mainly present in the sponge tissue, the more abundant the sponge tissue, the more liquid cells that may be contained, the more the tea flavor substance content in the leaves, the more abundant, the stronger the tea body feeling.
Large-leaf tea has a rich sponge tissue, which can store more abundant tea substances, so when we drink large-leaf tea, such as: Arbor Pu'er tea or red jade black tea, we can feel the tea taste is strong and strong, and the bitter taste is stronger. The sponge tissue of small leaf tea leaves is not as rich as that of large leaf species, and the subtle bitterness causes the taste buds to feel the fresh sweet taste brought by theaminic acid relatively easy for the taste buds, which is why we can feel the soft and sweet tea body of the tea soup when we drink oolong tea.
