Tian Yuming sniffed the taste of tea, and said, "I heard that by smelling the taste of tea leaves, you can distinguish good tea."
Xu Jiuyan said: “The aroma of green tea also varies with the place of production and the type of tea. The aroma of green tea is high and clear, and pure and sharp. Inferior product.
The odor also includes such unpleasant odors as sweetness, intensity, turbidity, mellowness, astringency and bitterness, heat, and the presence or absence of deterioration, sour, rot, smoke and mildew. The taste of green tea, just like the aroma, varies with the place of origin and the type of tea. Generally speaking, the sweetness and clearness, the richness and mellowness are the top priority. Those with weak taste, bitter and irritating are not top-grade. Although some green teas are slightly bitter, they also need to be bitter. Or those who suffer heavy numbness of tongue and throat are not top grade. When identifying the taste, the tea soup should not be too much. The tea soup in the mouth must be rotated from time to time so that Zhou Da is above and below the tongue, left and right, front and back. The tip of the tongue feels sweet and spicy, the tongue feels sour on both sides, the root of the tongue feels bitter, and the tongue feels salty. It must reach the whole tongue before it can distinguish all the tastes of tea. "
"What about the color and appearance of the tea?" Tian Yuming asked in detail.
Xu Jiuyan patiently said: "No matter any green tea, the green tea is clear and clear, and the water color is strong. It is not good if it is yellow and turbid, or has free deposits. But sometimes it is to meet the needs of consumers. If the water color is yellow but not blue, it is another matter. When identifying the water color, the cup must be slightly tilted from time to time, paying attention to whether there are any free substances.
For any green tea, the bottom of the leaf is greenish green, the leaf buds are delicate and even, the color is bright, and the leaf expands first. The leaf background is dull and dull, old and tender, cracked, curled, astringent without hairs, or mixed with green and black patches, or with irregular color, withered but not moist, and blistering, all of which are inferior.
The appearance of fresh green tea is bright green and shiny, with a strong tea fragrance; the tea soup made is green in color, with a refreshing fragrance, orchid fragrance, cooked chestnut fragrance, etc., the taste is sweet and refreshing, and the bottom of the leaf is bright green and bright.
The appearance of stale green tea is yellow and dull, dull, and has a low aroma. For example, if you breathe hot air on the tea, the leaves are yellow and dry in the wet area, and they smell cold; the tea soup is dark yellow in color, and the taste is mellow but not Refreshing, the bottom of the leaf is not bright enough.
The appearance of spring tea is strong and plump, dark green, moist, tightly knotted, and thick; the tea soup made is strong, sweet and refreshing, with a strong aroma, and the bottom of the leaf is soft and bright. The shape of summer tea is coarser and looser, the color is mixed, and the leaf buds are clearly woody; the tea soup made is astringent, the leaf base is hard, the veins are exposed, and the copper-green leaves are mixed. "
Tian Yuming was very interested and asked: "Then how do I judge good tea or bad tea?"
Xu Jiuyan put down the tea cup, looked at the tea in the tea bottle, and said, “What about bad tea? The mildewed tea is sluggish in color. The root of the tongue is bitter and heavy. The aroma and taste are moldy. Soaking in water is not easy to unfold. The sour tea has a weak taste. , Low aroma, sour aroma and taste, the bottom of the leaf is purple. The aroma and taste of the burnt tea have a burnt taste, the bottom of the leaf is cracked, and the bubbles are spotted, the bitter and more precipitated, the smell of smoke is smokey Smelly, irritating throat when eating, it makes you want to cough. Chen tea is dry and not moist, has a stale air, the water is yellow and turbid, it is not easy to expand in water. Huilong tea is light and dull in color, and very light, chewing light and tasteless, and not bitter , It unfolds very quickly when soaking in water. The flavor of fermented tea is not correct, the water color is yellow turbid or red, and the bottom of the leaf is red. The flavour and taste of the tea are both rotten. The bottom of the leaf is purple, dark and dull, water color Yellow muddy.
When the price of tea is high, there are also unscrupulous people who are mixed with fake tea such as wintergreen, willow leaves, peach leaves, camellia, manshan green, or mixed with impurities such as silt. The fake tea stems are square and flat, with different lengths, soft and hard cords, different colors, shapes, and fragrances. Soaking in water is slower to unfold, the bottom of the leaves is narrow and long, the teeth are large and thick, and the veins are not raised. Broken, dry and without hair. The tea mixed with mud and sand, the color is dark and dull, and it feels heavier in the hand. If you press it hard, there will be sand and sand, the water is turbid, there is a lot of precipitation, and the bottom of the leaves rubs like fine sand. "
Tian Yuming smiled suddenly and asked, "Are you Feng Yuan's student?"
Xu Jiuyan also smiled and said, "Yes, she is my high school biology teacher."
Tian Yuming stood up, took a photo album from the cabinet, opened it to Xu Jiuyan, and said, "Look, this is the first time I met Feng Yuan. At that time, I saw it first. When I arrived at her, I thought I liked her character so much, I really wanted to chase her. I asked her about her contact information everywhere. Whenever I had time, I went to Nanyi City to find her. After looking for her several times, I stopped going. NS."
"Why?" Xu Jiuyan asked.
Tian Yuming said: "Because she is married."
Xu Jiuyan smiled and said, "Then do you know who her husband is?"
"It's this breath that I can't swallow the most. I haven't seen her husband's face right now, this grievance!" Tian Yuming said leisurely.
Xu Jiuyan asked again: "Then do you know what Feng Yuan does?"
"Teacher Feng Yuan, Teacher Feng Yuan, of course he is the teacher!" Tian Yuming said naturally.
Xu Jiuyan laughed haha and said, "Then it's no wonder you can't catch up with them."
Tian Yuming asked with some doubts: "How do you know?"
Xu Jiuyan waved her hand and said, "You don't need to know about this. Anyway, Teacher Feng Yuan also found true love, didn't you?"
Tian Yuming nodded and said, "You are right, so do you understand?"
Xu Jiuyan paused, then nodded and said, "I think I should understand a little bit."
"Then tell me, I find that I seem to like listening to you very much." Tian Yuming said interestingly.
Xu Jiuyan smiled slightly and said: "I think I will handle the relationship between work and life. I must do a good job and live a good life. It doesn't need to be happy, plain and sweet. As for this tea, as the old saying goes, Life is like tea, and tea is like life. Life can be as mellow as a good tea, and some bad tea can be as plain as water, a good life is as colorful as a good tea, and a bad life is as ineffective as a bad tea. This is the same as investigating a case. If you want to solve the case, you have to pay a price, sacrifice time and energy, separate good tea from bad tea, and find what we are looking for."
Tian Yuming laughed and said, "Well said, life is like tea, tea is like life, what a good point."
Xu Jiuyan said: "Team Tian, I am not as proficient in criminal psychology as Guan Zheng, but I will work hard to do better. The 6.28 case is very difficult, but I will do my best."
"Of course I believe you, Guan Zheng's vision can't be wrong." Tian Yuming patted Xu Jiuyan on the shoulder and said. (End of this chapter)
