（1） Color: To see the color of the wine, it is best to have a white background and place the glass in front of it. Of course, the color range depends on whether you taste white wine (hereinafter referred to as Baijiu) or red wine. The following are two kinds of wine colors: Baijiu has light yellow green, straw yellow, golden yellow, gold, dark gold, Madeira wine color and brown; Red wine comes in shades of purple, ruby, medicinal brick red, reddish brown, and brown. Color will tell you many things about wine, such as Baijiu. When they get old, they will deepen their color. On the contrary, red wine will lose its color.
（2） Shaking: Why shake the wine? To allow oxygen to enter the wine. I'm not sure if you're accurate yet, but I can tell you directly: shaking will release esters, ethers, and acetaldehyde, and with oxygen, create a fragrance in the wine.
（3） Wen Jiu: Now that you have shaken and released the aroma, what does the wine smell like? It has that form of NOSE, "NOSE" is a word commonly used by wine tasters to describe the overall aroma of wine. Accurately indicating the NOSE of a wine means that you can identify certain characteristics of the wine.
（4） Tasting: For most people, wine tasting refers to taking a sip of wine and quickly swallowing it. But this is not called wine tasting. Wine tasting is something that requires the taste buds to engage in. Remember it covers all around your mouth; On both sides of the tongue, the back of the tongue, the tip of the tongue, and extending to the bottom of the throat. If you drink wine like most people, you will overlook all the important taste buds.
The wine industry has an ancient tradition of integrity: 'Buy wine with apples, sell wine with cheese'. Apples can reveal defects in wine, while cheese tends to soften the aroma of wine, leaving you with a more pleasant taste.
（5） Aftertaste: When you have the opportunity to taste wine, sit back for a while and savor the wine you tasted, thinking about your experience just now.
