For mineral-rich water…

Mineral-rich water matters!

According to water sommelier Martin Ries, water from vending machines, convenience stores, etc. (pure water) contains almost no minerals and should not be drunk.

Pure water has no mineral content as if it were. We need minerals in our drinking water!

There is an indicator called TDS (Total Dissolved Solids). It refers to the concentration of mineral components (calcium, magnesium, potassium, sodium, bicarbonate, chloride, and sulfate) dissolved in water.

TDS is expressed in units of ppm, which is 1 ppm when 1 gram of mineral content is present in 1,000 liters of water. Usually, the TDS value for pure water is 1 ppm, and the lower the number, the less impure the water is, but without the necessary minerals! I had mistakenly thought that lower was better until now.

Impurities sound dirty, but since mineral content (=hardness) is also included in this category, it cannot be said that a high value is bad.

The average values are 100 to 160 ppm for tap water in Japan and 60-70 ppm for soft mineral water (or higher for hard water).

Try HILDON, the famous British water, available in Japan, (slightly carbonated water at 312 ppm)!
We drink it at home and it’s really good.

And you can buy this TDS measuring device on Amazon for under $2000!

Why does water taste different? What are the types and classifications of water?

There are different types of pure water! Let’s learn the difference between various types of water.
