Mineral water with “bubbles” is referred to as “carbonated” or “sparkling” (as in wine), without bubbles is referred to as “non-carbonated”, but you could also use “flat” or “still” (as in wine).

The problem with this (having read the other answers) is that in the English speaking world if you ask for ‘water’ you will most likely get regular water. If you want sparkling water (i.e. water with bubbles) you will have to ask for it. Or, at least, you will be asked for a clarification (i.e. do you want mineral water or regular water?) In some other countries, however, it seems to be the opposite. If you just ask for water (or its translation in whatever language) you are likely to get water with bubbles. So, you have to specify (depending on the country). For example, in Germany you have to specify ‘still water.’ No doubt other languages will have other words to specify ‘water without bubbles.’ And, interestingly, in Spain if you ask for milk (even for a child) it will come hot, in a coffee cup! If you then specify that you wanted it cold, it will come back exactly the same with a couple of ice cubes in it!

Sparkling Mineral Water and Still Spring Water.

I just read what’s written on the bottles in my pantry.

I think water with bubbles is usually called sparkling water. The opposite would just be regular water. You could say that it is flat because it is not sparkling, but I think that it is in it’s natural state so it just goes by the name water.

mineral water=spring water# ground water

sparkling water and maybe distilled water
