西湖龙井茶 色翠、形美、香郁、味醇

西湖龙井茶素有“色翠、形美、香郁、味醇”之美誉，长霉了的龙井茶会是什么样子，与茶毫又有什么区别呢？下面从龙井茶叶的外形、气味、触感、口感等几个方面来做区别，帮你一看便知。

外形

茶毫一般是均匀分布在茶叶表面的，龙井茶叶在制作的过程中，白毫会脱落一部分，集结成团，形成看上去像虫卵一样的白球。而霉菌是丝状成片分布的，通常分布在龙井茶叶受潮的部分。

气味

如果龙井茶叶发霉了，说明陈化的程度比较重了，这样的茶叶，闻起来会有比较重的陈味和霉味，有些甚至一打开包装，就会往外面冒烟。如果龙井茶叶是新鲜的，表面是茶毫，那闻起来就会比较清新。

触感

龙井茶叶的成品都经过了严格的干燥，如果发霉变质了，大多是受潮引起的，这样的茶叶捏起来是软软的，严重的会有腐化了的感觉。

汤色

西湖龙井茶叶一旦发霉了，冲泡起来会颜色暗黄，且非常浑浊，喝起来就会有“叮喉、麻、挂喉”的感觉。如果是茶毫，就不会有这样的感觉，茶毫多的茶叶，口感会非常鲜爽。

总之，倘若你不确定自己的龙井茶长霉了还是茶毫，冲泡一杯喝喝看。遇到闻起来有异味，或者喝起来有怪味的情况，需要考虑茶叶霉变了。

另外，区别龙井茶毫和发霉还有一招。无论龙井也好，还是其它茶叶，要知道茶毫是与生俱来的。如果龙井茶叶表面先前看不见类似绒毛、白毫的东西，但存放一段时间后，这类东西突然自己冒了出来，那么一般就是霉变了，这些“绒毛”其实是霉菌。

茶毫，是茶叶芽尖上面细小的绒毛，也叫茶毛，其中含有丰富的茶氨酸、茶多酚等营养物质，是茶叶嫩度的一个重要指标。一般来说，鲜叶的嫩度越嫩，茶毫就越多；茶毫越多，茶叶也就越嫩。茶毫很多茶都有，特别是绿茶、白茶等。

但并非所有的茶都可以一概而论，比如龙井茶，在加工过程中，有一道工序叫辉锅，辉锅的目的主要是干燥茶叶，促使茶叶香气物质的进一步形成，但它还有一个目的就是磨掉茶叶表面的茶毫，形成其特有的品质特点，所以龙井茶的嫩度并不能单看茶叶茶毫的多少来决定。

同一份龙井茶中，有些茶叶被磨干净了毫，所以看起来很干净，有些茶叶则没磨干净，所以会看见上面有聚在一块儿的茶毫。

茶叶发霉，一般是指茶叶中长出白毛，闻之带有霉味，严重霉变的茶叶会腐烂结块，上面长出绿毛，普洱茶还会有黑色的霉变。茶毫是自然现象，不会影响人体的健康。但是，如果茶叶已经发霉，就要谨慎，最好不要喝，对身体有害!

茶叶发霉是因为受到了青霉、曲霉污染，能产生如黄曲霉毒素等有害物质。黄曲霉毒素被世界卫生组织癌症研究机构划定为一类致癌物，是一种毒性极强的剧毒物质。

黄曲霉毒素耐高温，无法经过高温煎炸烹调消除，会破坏人及动物肝脏组织，严重时可导致肝癌甚至死亡。所以，喝了发霉的龙井茶轻则头晕、眼花、腹泻等，重则引发诸如肝、肾等重要器官的病变。对于发霉或已经变质的龙井茶叶，无论花多少价钱买的，最好不要饮用了。

West Lake Longjing tea is known as "green in color, beautiful in shape, fragrant and mellow in taste". What will moldy Longjing tea look like and what is the difference between it and tea? The following is the difference between the shape, smell, touch, taste and other aspects of Longjing tea, so that you can see it at a glance.

shape

The tea cents are generally evenly distributed on the surface of the tea leaves. During the production process of Longjing tea leaves, a part of the white cents will fall off and gather into clusters to form white balls that look like insect eggs. The mold is distributed in filamentous pieces, usually distributed in the damp part of Longjing tea.

odor

If the Longjing tea is moldy, it means that the degree of aging is relatively heavy. Such tea will smell relatively musty and musty, and some will even smoke outside when the package is opened. If the Longjing tea leaves are fresh and the surface is covered with tea leaves, it will smell fresher.

touch

The finished products of Longjing tea have been strictly dried. If they become moldy and deteriorated, most of them are caused by moisture. Such tea leaves are soft when pinched, and in severe cases, they will feel corrupted.

soup color

Once the West Lake Longjing tea is moldy, it will be dark yellow and very turbid when brewed. If it is tea, there will be no such feeling. Tea leaves with more tea will taste very fresh.

In short, if you are not sure whether your Longjing tea is moldy or tea, brew a cup and drink it. If it smells peculiar, or tastes strange, you need to consider that the tea leaves are moldy.

In addition, there is another trick to distinguish Longjing tea from mildew. Whether it is Longjing or other teas, you must know that tea is innate. If things like fluff and pekoe could not be seen on the surface of Longjing tea before, but after a period of storage, such things suddenly appear on their own, then it is generally mildewed, and these "fluffs" are actually molds.

Tea cents are the tiny hairs on the tip of tea buds, also called tea hairs, which are rich in nutrients such as theanine and tea polyphenols, and are an important indicator of the tenderness of tea leaves. Generally speaking, the more tender the fresh leaves, the more tea leaves; the more tea leaves, the more tender the tea leaves. There are many kinds of tea, especially green tea and white tea.

But not all teas can be generalized. For example, Longjing tea, in the process of processing, there is a process called Huiguo. The purpose of Huiguo is mainly to dry the tea leaves and promote the further formation of tea aroma substances, but it also has the purpose of grinding The tea leaves on the surface of the tea leaves form its unique quality characteristics, so the tenderness of Longjing tea cannot be determined by the number of tea leaves alone.

In the same batch of Longjing tea, some tea leaves are ground clean, so they look clean, while some tea leaves are not ground clean, so you will see a bunch of tea leaves on it.

Moldy tea leaves generally refers to the growth of white hairs in the tea leaves, which smells musty. Severely moldy tea leaves will rot and agglomerate, and green hairs will grow on them. Pu-erh tea will also have black mildew. Tea is a natural phenomenon and will not affect the health of the human body. However, if the tea has been moldy, be cautious, it is best not to drink it, it is harmful to the body!

Moldy tea leaves are contaminated by Penicillium and Aspergillus, which can produce harmful substances such as aflatoxins. Aflatoxin is classified as a Class I carcinogen by the World Health Organization Cancer Research Agency, and is a highly toxic and highly toxic substance.

Aflatoxin is resistant to high temperature and cannot be eliminated by high-temperature frying and cooking. It will damage human and animal liver tissue, and in severe cases can lead to liver cancer and even death. Therefore, drinking moldy Longjing tea can cause dizziness, vertigo, diarrhea, etc., and serious diseases such as liver and kidney. For moldy or spoiled Longjing tea, no matter how much you bought it, it is best not to drink it.
