What is a hanging cup? Wine is different from water. The wine liquid distributed around the wall of the wine glass will produce a tension that prevents the wine from falling quickly. This is called a hanging glass. The surface tension of wine is also different due to different alcoholic contents, or due to different types and contents of other components in the wine. Of course, this can also be used to test whether there is too much water in the wine, but it can be summarized simply as good wine can be plentiful and lasting in the cup.
People who are good wine tasters also have a habit: gently shake the unopened wine and then turn it upside down to look at the hops, which is a layer of foam formed on the surface of the wine. What are you looking at? "Tiao Ding Ji" once summarized: "Shochu, the one with clear blue flowers and fine flowers is at the top, the flowers with thick and sparse flowers are second, and the flowers with no flowers are muddy at the bottom."
"It means That is to say, if the hops are thin and high, it is a good wine, and the price will naturally be high.
In fact, the quality of wine cannot be judged entirely by the hops. To be precise, looking at the hops can only roughly judge the alcohol content. Of course, before the Republic of China, private soju workshops did not have a concept of alcohol content. Looking at the hops became an objective criterion for determining the price of wine at that time.
But it is undeniable that both hanging cups and hops use the same principle - tension. Therefore, the more tempered it is over the years, the more mellow and sweet the wine is, the better its tension will be, the finer and taller the hops will be. It is numerous and long-lasting.
