What Is “TIANSHEN 25X Cold Brew Concentrate”?
You may have tried cold brew coffee before,
but you may not yet know this—TIANSHEN 25X Cold Brew Concentrate is an ultra-high-strength coffee liquid made with patented cold-extraction technology.
Why does a bottle of water taste “smooth and pleasant”?
The answer often lies in its mineral balance, TDS (Total Dissolved Solids), and hardness level. Tianshen Water delivers a refreshing, comfortable mouthfeel because its composition is perfectly balanced born from a deep underground spring hidden beneath sacred volcanic land.
With a TDS of about 163 mg/L, Tianshen Water sits in the medium range.That means it strikes harmony between crisp lightness and mouthfeel support:
Too low TDS → feels “empty” or “thin.”
Too high TDS → tastes “heavy” with noticeable mineral tones.
Tianshen Water hits the sweet spot — neither heavy nor light, just perfectly smooth.
Water hardness depends mainly on calcium and magnesium content. Tianshen Water has only 0.5 mg/L of hardness exceptionally low, preventing any chalky or sticky sensation.Even at room temperature, it feels clear and clean — the reason you keep wanting another sip.
Tianshen Water contains calcium, magnesium, potassium, sodium, and trace iron and zinc.
Calcium & Magnesium → Add structure and body
Potassium & Sodium → Bring roundness and a hint of natural sweetness
Iron & Zinc → Create a crisp and clean finish
This balanced composition enhances the aroma and clarity of tea or coffee when brewed with Tianshen Water.
With a pH of 9.7, Tianshen Water is naturally weak alkaline — not a medical claim, but a reason why many people describe it as soft on the palate and smooth on the throat.
Sourced from a single volcanic aquifer beneath Sakurajima in Kagoshima, Japan, naturally filtered through volcanic rock and sterilized at 85 °C with hot spring steam, it preserves its pure, fresh essence.
Behind the numbers is the feeling — water that tastes clean, smooth, and comforting.
