A taste test review of 'Asahi Delicious Water Natural Water Salty Grapefruit,' a refreshing and easy-to-drink beverage that also helps prevent heatstroke.

The '

Asahi Delicious Water ' brand, which offers natural water from various regions, added ' Asahi Delicious Water Natural Water Salty Grapefruit ' on May 19th, 2026 (Tuesday), which is characterized by its refreshing sweet and sour taste and is said to be suitable for preventing heatstroke, so I bought some and tried it.

The packaging looks like this. The word 'Salty Grapefruit' stands out more than the word 'Water,' which is common to the 'Asahi Delicious Water' series.

The ingredients include natural mineral water (deep well water), high fructose corn syrup, grapefruit juice, and salt. It contains 28kcal per 100ml, or 168kcal per 600ml bottle. It also contains 0.11g of salt per 100ml, and the addition of salt and vitamin C makes it a drink that helps prevent heatstroke.

The liquid is transparent, with a slight yellowish tint. While it has a grapefruit flavor, it's quite light and easy to drink, without any lingering sweetness or sourness in the mouth. The salt content is well-balanced and barely noticeable. There's also no bitterness from the grapefruit. Relying solely on this for hydration would be overkill, but I got the impression that it's a drink that could be helpful to have on hand as a backup.

'Asahi Delicious Water Natural Water Salty Grapefruit' has a suggested retail price of 189 yen (tax included) and will be released on May 19, 2026. On Amazon, a 24-pack was being sold for 2386 yen (tax included) (99 yen per bottle).
