What gives water its taste?
Water taste is impacted by several different factors, ranging from where it comes from to the tap it is poured out of. While some water may taste sweet, others can taste chalky or even metallic. These are the main factors that influence water taste:
- Source: the origin of your water significantly influences its mineral content, and the chemicals used during processing, both of which play a key role in shaping its taste.
- Treatment: local water authorities use different chemicals, such as chlorine, to sterilise the water to make it safe for consumption. Read our article on how water is treated for more information.
- Mineral content: both occurring naturally and added to water, minerals dictate whether the water is hard or soft. Water from areas with more limestone tends to be hard, while those with granite are often softer. Learn more about water hardness in our helpful guide.
- Pipes and distribution: from the pipes that carry the water away from the source to your own tap, the materials and age of metals such as iron can impact the water’s taste.
- Environment: rainfall and climate can influence water quality, leading to changes in taste.
- pH levels: all of the above factors can influence water’s pH levels. If water becomes too acidic or alkaline, the taste may be compromised.
- Temperature: though specific to the individual, many perceive water to taste different when it is hot or cold.
