Water that comes from nature can be called normal water or regular water. On the other hand, mineral water is simple water comprised of certain minerals like calcium, magnesium, potassium, and zinc. Water comes from different sources. You can get mineral water plain or sparkling, depending upon your preference.
Water comes from rivers and lakes, which is procured only from regions that are rich in minerals. Water, which comes from a plethora of different sources, can be termed as being mineral water. You can have plain water and add the minerals to it to make it mineral water.
When you compare plain tap water to purified mineral water, there is a big difference in the taste between the two, especially if you are a water snob. Tap water does not have a very clean or refreshing taste. Mineral water and bottled water, on the other hand, has a clean, fresh taste, which is quite thirst-quenching and refreshing.
