We Jincheng people love orchids, which are old vinegar and genuine.
Vinegar is all the same as long as you don't buy those cheap ones. Cheap to say that fermented vinegar is actually pure blended vinegar and edible glacial acetic acid, not even vinegar. Vinegar depends on the degree first. Generally, aged vinegar is 3.5 _6, and over 6 is called aged vinegar. According to national regulations, aged vinegar can have no shelf life and does not need to add additives and preservatives. Then, look at the ingredients list to see if there are any additives such as sodium toluene, potassium sorbate and caramel pigment. Spices are pepper particles that add flavor. Don't look at their years, they are all scribbled. Look at your photos. They are old vinegar. Look at the list of accessories to see if there are additives, and then see if there is precipitation. If there is precipitation, it is good vinegar. Ninghuafu's vinegar is relatively high-end, and Zilin's is more popular. Orchids are only popular in Jincheng. According to national standards, it's all the same. They are all fermented vinegars GT 18 187+. The mature vinegar is also 18 187, but Shanxi mature vinegar is a geographical indication protection standard. Jincheng is not within the scope, so orchids can't be produced, but it can be produced in the East Lake of Huafu, Zilin Ning, but it is rare. I don't know the implementation standard.
If you really want to buy vinegar, you should find a small workshop and look at the production process. The mass sales are large, the output is limited, and the vinegar takes a long time to make. Blending when supply exceeds demand (legal).
Shanxi mature vinegar is world-class, and everything is fine.
