What's inside your water.
Every scan reads the six values that shape how a water tastes.
Adds structure and a clean, chalky finish.
Rounds the palate with a soft bitterness.
Sharpens flavor and salinity.
Softens acidity and lifts the mid-palate. Pairs beautifully with rich food.
The overall mineral weight. Low tastes light and quiet, high tastes full and complex.
Acidity or alkalinity on a 0-14 scale. Shifts perceived crispness and smoothness.
Read from any bottle scan, in seconds.
A sommelier's vocabulary for water.
Low mineral weight. Quiet, silky, disappears cleanly. Ideal for delicate dishes and tea.
Moderate minerals. Rounded, versatile, at home with almost any meal.
High minerals and bicarbonate. Structured, savory, built to stand up to rich food and wine.
Every drop that reaches your glass has spent thousands of years traveling through ancient rock, volcanic springs, and glacial ice, absorbing minerals, developing character, becoming something entirely its own.
Just like wine has terroir, water has a story. Most people never stop to read it. You will.
“Water has terroir. Water has complexity. Water has been waiting for a sommelier.”

Questions, answered.
What is water TDS?
TDS stands for Total Dissolved Solids - the combined amount of minerals dissolved in your water, measured in mg/L. Low TDS tastes soft and light, while high TDS tastes rich and complex. Water Sommelier reads the TDS of any bottle so you know exactly what you are drinking.
What does water pH mean?
pH measures how acidic or alkaline water is, on a scale from 0 to 14, where 7 is neutral. It is one of the two numbers a scan puts on the scan card, alongside TDS, because both shape how a water tastes.
How does the bottle scan work?
Open the app and photograph any bottle. The scan identifies the water and puts its pH and TDS on the scan card, and every scan is kept in My Water. For tasting, sources or food pairings, ask the built-in Water AI.
