A mineral concentrate calibrated to match Terres de Café's coffees, drop by drop.
The water you brew with carries as much information as the coffee itself. Minerals shape how sweetness lands, how acidity resolves, and how texture sits on the palate, often before a coffee's own character gets a fair hearing. This concentrate was developed to close that gap, giving Terres de Café's coffees a water profile built specifically to draw out what's already in the cup.
A Collaboration in Precision
Terres de Café is a French specialty coffee roaster, known for refined sourcing, responsible agriculture, and coffees built around brightness, structured sweetness, and an elegant, coating mouthfeel. Matching that profile consistently depends on the water it's brewed with, which is what led to this collaboration with APAX LAB, a lab focused on precision water design for coffee.
The result is a concentrate developed specifically to match Terres de Café's coffees: engineered to reveal brightness, lift sweetness, and support a coating texture, so each coffee can express its full aromatic range. It functions less like a water treatment and more like a seasoning for coffee, giving you a tunable way to adjust the brew, whether that's mixed into your brewing water ahead of time or added straight into the cup.
What the Concentrate Brings
- Brightness and clarity: Lifts liveliness in the cup and sharpens the definition between flavor notes.
- Refined sweetness: Supports a rounder, more structured sweetness rather than a flat or thin one.
- Silky, coating mouthfeel: Adds body and texture that carries the coffee's flavor further across the palate.
How to Use
Shake the bottle thoroughly before use. Add the concentrate to your brew water at 3 to 4g per liter, or add it directly into a brewed cup: 1 to 10 drops per 200mL is the standard range. Demineralized water is recommended as the base, since it gives you the most control over the remineralization process. The concentrate is not intended for direct consumption on its own, and it should not be used inside espresso machines.
Ingredients: Water, magnesium chloride, calcium chloride, magnesium citrate, silica, sodium chloride, potassium bicarbonate, sodium bicarbonate.
