The most important part of Wine tasting is to enjoy it and have fun. There are five important steps to tasting wine which are described below.

See the Color  - Take a look at the color of the wine you are about to taste, it will give you a good indication on the age of the wine. Young white wines are clear and look like water, while older wines that have been aged in oak get a gold tint. Young red wines are vivid purplish red while older wines have brownish tones. 
Swirl the wine - Swirling the wine helps to expose the wine to more oxygen and release its aroma, this is called as aerating the wine. Watch how the wine runs down the glass. If the streaks of wine are thick and run relatively slow the wine has more sugar or alcohol. If the wine is thin and runs down the glass fast it has less alcohol. 
Smell the wine - After you swirl the wine take a sniff and it will smell much more vibrant. There are three types of aromas that wines have: primary are  fruity or floral, secondary ones come from aging in the barrels and tertiary are aging signs.
Sip the wine - Take a sip of the wine and spread it around your mouth to detect the different type of taste it provides. The tip of the tongue will give you the sweetness while the sides give you a good indication of sourness or acidity. 
Savor the wine- How does the wine feel after. Does it leave a bitterness or leathery feel on your tongue, it means the wine has more tannins.Does the wine feel light or dense , will give you a sense of whether it is light or medium bodied. 

After you have gone through the steps the most important thing is if you liked the wine. Take notes after each taste and you will eventually find out the type of wines you like.
