The process is quite simple. The wine will be provided in a glass with typically a very little amount of wine. The reason being is because all you really need is one sip. Wine tasting can be broken down into four components: swirling the wine around your tongue, smelling the wine, tasting the wine, and spitting it out.
When tasting wine, three aspects to evaluate are taste, color and clarity, and smell. By swirling the wine in the glass, you can judge whether the colors are lighter or darker, and also how light affects the color. After a while, you should be able to detect specific flavors such as vanilla, citrus, or berries.
When examining the wine's appearance, you want to judge the consistency of the color. Hold it up against a light background and see if you see any traces of any other color, mainly focusing on the area between the edge and middle of the glass. Any variation could be attributed to oxidation, but it could also mean that it is an issue that will impact the taste.
Most wines will fall under only a few categories when smelling the wine. Either the wine will smell floral and fruity, or will be a bouquet scent, which actually originates from the winemaking process. Eventually, you should be able to recognize these categories of scents when wine tasting.
