Have you ever been in a situation where someone is describing how delicious their wine is, while when you try it, you don't understand what they are talking about and just get "the taste of wine"? Well, there are actually many skills in wine tasting that can help you appreciate wine better.
Firstly, by looking at the glass of wine, the color can give you some hints. Usually, when you see the edge of red wine which has some hint of "garnet" or "amber" in white wines, it means the wine has spent some time for maturation and you can expect some sort of "dried fruit" characters in the wine.
Secondly, we have to smell the aroma of wine before we taste it. Most of the descriptors of the wine are from nosing. However, you may wonder wine is made from grape juice, why are there so many aromas in it? In fact, wines are made from grape juice, but the flavors and aromas come from the grapes themselves and the winemaking process. Those descriptions are the smell of the compounds found in the wines. Focusing on the nose helps you to get the aromas and understand the profile of the wine.
Finally, it comes to tasting the wine on our palate. Normally, when we drink wines and other beverages, we take a sip and swallow it directly, which gives us only a little information about the wine. Next time, try to have a bigger sip and swirl the wine in your mouth for a few seconds before you swallow it. You will get a lot more from the wine by letting every part of your tongue and your gums contact the wine. You will get a lot more in mouthfeel and flavors of the wine.
