Comparing Mineral Waters in Thailand | Differences in Drinkability and Hardness, and Recommended Choices

Which mineral water should you choose in Thailand?
With a wide variety of mineral waters available in Thailand, many may wonder which one to choose.
In fact, the drinkability and use of water change depending on its "hardness," so it's important to choose according to your purpose.
This article provides an easy-to-understand guide to the characteristics and selection of water available in Thailand.
Mineral water differences determined by "hardness"
"Hardness" is important for understanding the differences in water.
・Hard water: High in minerals, with a distinct taste.
・Soft water: Low in minerals, with a smooth mouthfeel.
In Thailand, there is a lot of water with relatively high mineral content, and some people find it tastes "heavier" compared to Japanese water.

For example, Onsensui99, natural water from Tarumizu Onsen in Kagoshima Prefecture,
is ultra-soft water with a hardness of 1.7, characterized by its soft and smooth mouthfeel.
Despite being alkaline with a pH of 9.9, it has littleクセ (strong taste or aroma),
and is known as water that is easy to incorporate into daily hydration.

"Continuity" is key for water

so choosing water that can be consumed without effort leads to a comfortable life.
