Apax Lab Mineral Concentrates

Liquid mineral additives for coffee, the Apax Lab Mineral Concentrates are designed to change how brewed coffee tastes by adjusting the mineral content of your water. Added either before brewing or directly into the cup, they allow you to control acidity, sweetness, body and overall balance without changing your coffee or brew method. This gives you a more direct way to influence flavour, whether you’re working with different coffees or trying to get more out of a single setup.

Rather than affecting extraction itself, these concentrates work by altering how flavour is expressed once the coffee is brewed. By changing how compounds are perceived in the cup, they allow you to refine balance and improve clarity without needing to adjust grind size, dose, or technique. This makes them useful for dialling in recipes, correcting imbalances, or exploring how the same coffee presents under different mineral conditions with small, repeatable changes.

Tonik

Designed to increase perceived acidity and bring more structure to the cup. It works well with coffees that feel flat or muted, helping highlight brightness and improve separation between flavours. The result is a cleaner, more defined profile without adding harshness.

Jamm

Shifts the balance toward sweetness and weight, rounding out sharper coffees and adding depth to lighter profiles. It increases perceived body and smoothness, making it particularly effective for coffees that feel thin or overly bright.

Lylac

Focused on improving texture and aromatic expression. It softens acidity and brings forward more delicate notes, helping create a smoother, more refined cup. It works best with lighter or more complex coffees where subtlety matters.

Konflux

Designed as a testing and blending tool, allowing you to explore how different mineral balances interact. Rather than targeting a single outcome, it gives you a way to build and refine your own profiles, making it useful for learning and experimentation.
