Why do tea, coffee and soft drinks taste better with filtered water?
Water is a very good natural solvent and helps develop the aroma of coffee and tea. The amount of temporary hardness (limescale) in the water affects the dissolution of aromatics, for example in tea and coffee. The higher the proportion of limescale in the water, the lower the ability to dissolve. The aroma of tea and coffee develops better in water with a low limescale content.
