What Is San Pellegrino Water?
San Pellegrino comes from a thermal spring in San Pellegrino Terme, in the Italian Alps of Lombardy. The water rises naturally rich in minerals and is lightly carbonated with added CO₂ to a consistent level.
San Pellegrino Water pH Level: Is San Pellegrino Water Acidic or Alkaline?
San Pellegrino Water has a typical pH of 7.6 – 7.8 — slightly alkaline.

Why San Pellegrino Water has a pH of 7.6 – 7.8
Calcium
Around 208 mg/L of calcium — among the highest of mainstream sparkling waters.
Magnesium
About 56 mg/L magnesium contributes to both taste and natural buffering.
Bicarbonate
High bicarbonate content (≈219 mg/L) buffers the carbonic acid from CO₂, holding pH at 7.6–7.8 — alkaline despite the bubbles.
At-source vs. as-sold
7.6–7.8 is the pH of the water at its Lombardy spring, before carbonation. Once bottled and carbonated, dissolved CO₂ can pull the tested "as sold" pH down closer to 5.6–5.9 in some lab reports — the same effect that makes any sparkling water read more acidic than its still, at-source value. Both figures describe the same water at different points in production.
Is San Pellegrino Water safe to drink?
Yes — and notable for being one of the few sparkling waters with an alkaline pH. Most sparkling waters fall to pH 5.5–6.5; San Pellegrino's high bicarbonate is the reason it stays alkaline.
Frequently asked questions
How can San Pellegrino be alkaline if it's sparkling?
Its very high bicarbonate level (≈219 mg/L) buffers the carbonic acid that CO₂ creates, holding the final pH at 7.6–7.8.
What's the pH of San Pellegrino vs Perrier?
San Pellegrino is much more alkaline. San Pellegrino sits at 7.7; Perrier reads around 5.5 because it has less bicarbonate to buffer the CO₂.
Is San Pellegrino good for digestion?
Bicarbonate-rich sparkling waters like San Pellegrino are often associated with mild digestive benefits, though the evidence is preliminary.
