Romanian Mineral Water: Sparkling or Flat?
When I first arrived in Romania, one detail about Romanian mineral water immediately caught my attention. Older locals often referred to “mineral water” as if it meant only one thing: sparkling water. If you asked for “apă minerală,” you would almost always be given a carbonated bottle, while still water was treated as something entirely different.
Under the Communist Regime: only “Mineral” or “Tap” Water.
Curious about this distinction, I was told a simple but revealing explanation rooted in history. During the communist period, bottled water production focused almost exclusively on naturally sparkling mineral sources. Still water, on the other hand, was not commonly bottled and was generally associated with tap water. As a result, the term “mineral” became culturally linked only to sparkling varieties.
Nowadays: towards an International Standard
Even today, this legacy is visible on store shelves across the country. You will rarely, if ever, find a label that says “mineral flat water” in Romania. Instead, bottles clearly distinguish between apă minerală (sparkling) and apă plată (still), reflecting a historical perception that continues to shape how Romanian mineral water is understood and consumed.
My Favourite Water
My personal preference goes to Borsec still water. I appreciate its balanced taste, which makes it suitable for everyday drinking without being too heavy or too light.
My first Water in Romania
When I first moved to Romania, my situation was quite different. At the time, I was living with a Romanian partner and, due to practical constraints, I adapted to drinking Izvorul Minunilor. It was a simple, accessible choice, and like many things when you relocate, you get used to what is available around you.
Over time, our needs changed. Today, we are a family of three, living on the fourth floor of a building without a lift. Carrying bottles of water upstairs quickly became impractical. This is one of the compromises we accepted in order to live in a pleasant area of Bucharest at a reasonable cost.
The solution: Water Delivery & Dispenser
For this reason, we stopped buying bottled mineral water from stores and switched to home delivery. We currently use Acua Aquavia, distributed by H2ON SRL, which delivers large water containers directly to homes and offices. In Bucharest, a similar service is also offered by La Fântâna.
This experience also shows how, beyond composition and marketing, the “best” water often depends on lifestyle, logistics, and daily habits.
A Country rich of Mineral Water
Romania is one of the richest countries in Europe when it comes to natural mineral water resources. Thanks to the Carpathian Mountains, underground geological formations create a wide variety of mineral compositions, giving rise to dozens of bottled waters with distinct chemical profiles.
A great variety of Mineral Waters
Unlike many Western European markets, where branding dominates perception, Romanian mineral waters differ substantially in mineral content, carbonation, and health impact.
This guide provides a complete, structured overview of Romanian mineral waters, including:
- Major brands
- Mineral composition (where available)
- Natural vs added CO₂
- Classification by type
- Health considerations
🧪 How Mineral Waters Are Classified in Romania
Before analyzing individual brands, it’s essential to understand classification.
By Mineral Content (Residue at 180°C)
- Oligomineral water (< 500 mg/L)
- Medium mineralized (500–1500 mg/L)
- Highly mineralized (> 1500 mg/L)
By Chemical Composition
- Bicarbonate waters (digestive support)
- Calcium-rich waters (bone health)
- Magnesium waters (muscle & nerve support)
- Sodium-rich waters (to be limited in hypertension)
By Carbonation
- Still (flat)
- Naturally sparkling (CO₂ from source)
- Artificially carbonated
👉 In Romania, many waters are naturally carbonated, a key differentiator.

🧠 How to Choose the Right Mineral Water
Daily hydration
- Low mineral (e.g., Bucovina, Aqua Carpatica)
Digestion support
- Bicarbonate-rich (e.g., Borsec, Zizin)
Occasional therapeutic use
- High mineral waters (e.g., Biborțeni)
