Besides "Spindrift", are there any other unsweetened flavored sparkling water brands that the flavor is so strong you can describe it as tasting like "unsweetened soda"?:
I've tried "La Croix", "Bubbly", "Aha", "Waterloo", & "Perrier" and none of them have as strong a flavor as "Spindrift". Because of this, sweetening by adding liquid stevia drops works well with "Sprindrift", but it doesn't work well with the other brands I mentioned. The stevia just ends up overpowering the flavor in those other brands. After reading this thread though I'm considering what some posters have suggested, adding a little bit of lemon or lime juice for flavor to the other brands.
