Liquid rock extract explanation

Liquid Rock is Bluewater’s mineral concentrate that adds calcium and magnesium to purified water, creating stable, great-tasting, scale-free water for drinking and coffee brewing.

Liquid Rock

Liquid Rock is Bluewater’s proprietary mineral concentrate used to remineralise purified water with a balanced mix of calcium and magnesium. It is designed to deliver stable, great-tasting, and scale-free water for both drinking and professional coffee brewing.

What Is Liquid Rock?

Liquid Rock is a food-grade solution that contains minerals sourced from Sweden. It is automatically dosed into purified water using Bluewater dosing pumps and control systems to achieve a precise and repeatable mineral profile. It is used in systems like Café Station, Kitchen Station and setups with Bluewater Pro or Spirit paired with dosing control.

Key Composition and Properties

Liquid Rock is certified food-grade and produced under controlled quality standards. The mineral source in Sweden is selected for its purity and consistency, ensuring every container delivers the same reliable mineral profile.

  • Calcium and magnesium in a 2:1 ratio

  • No added sodium

  • Formulated for optimal coffee extraction, hydration, and machine protection

  • Delivers stable TDS and taste profile with no scaling

  • Supplied in sealed containers for hygiene and easy handling

Key Benefits

  • Improves taste: Minerals enhance flavor, mouthfeel and extraction balance

  • Supports health: Provides essential minerals with no added salt

  • Prevents scaling: The formula is engineered to avoid limescale, even under heat

  • Consistent results: Enables repeatable water quality across locations

  • Efficient use: One container yields hundreds of litres of mineralised water — making it highly efficient for both home and commercial use

How It Works

  • The solution is stored in a dedicated container connected to the dosing pump

  • The Bluewater Control Box manages the dosing process, based on tank levels and demand

  • Mineralisation occurs after purification, ensuring the cleanest possible water with controlled mineral content

  • Dosing can be adjusted depending on the desired profile: low, medium or bold mineralisation (when supported by the system)

Used With

  • Café Station

  • Kitchen Station

  • Spirit + Control Box setups

  • Pro + Control Box setups

Handling and Maintenance

Note: Always handle Liquid Rock with clean, dry hands. If the concentrate contacts surfaces, rinse immediately with water. Refer to the product Safety Data Sheet (SDS) for full handling precautions.

  • Containers are sealed and easy to replace

  • Air in the dosing line can be purged by holding the button on the dosing pump until the light turns green

  • Store at room temperature in a cool, dry place away from direct sunlight.

  • Change the container when level is low or when notified by the system interface
