Water · Minerals · Precision
A cup of coffee is about 98% water.
Season the other 98%.
The minerals dissolved in your water quietly decide how sweetness, acidity, body and clarity reach the cup. APAX LAB turns that hidden variable into something you can control: three concentrates that let you tune your brew water precisely and repeatably, a few drops at a time.

Opens up clarity and a silky, floral elegance, made for delicate, high-grown lots.
How to use
Three steps
to your water.
Start from demineralised or soft water so nothing competes with the profile you are building.
Shake
Shake the bottle well so the mineral blend is evenly distributed before you dose.
Dose
Add 3 to 4 g/L to your brew water, or 1 to 10 drops straight into a 200 ml cup, to taste.
Taste & repeat
Note what changed, adjust the drops, and lock in a recipe you can pour again and again.
Why does brewing water change the taste of coffee so much?
Brewing water changes the taste of coffee so much because it is both the solvent and the main ingredient of the cup. A filter coffee is about 98 percent water. The minerals dissolved in it help decide which compounds are extracted from the ground coffee and how they taste afterwards. Magnesium and calcium bind flavour compounds and carry sweetness and body. Bicarbonate buffers acidity: too much of it makes coffee flat, too little makes it taste sharp. Tap water varies from region to region in hardness and bicarbonate content, which is why the same beans taste different in two places. If you build the water yourself, this variable becomes something you control. The APAX LAB Box Set contains three mineral concentrates of 100 ml each for that purpose: TONIK, JAMM and LYLAC. The dosage is 3 to 4 g per litre of brewing water or 1 to 10 drops per 200 ml, starting from demineralised or soft water under 30 ppm. One bottle lasts for about 150 brews.
Box Set or KONFLUX: three directions or one
Both products come from APAX LAB and are dosed the same way. The Box Set covers three flavour directions with three concentrates, while KONFLUX focuses on one: mouthfeel. The values come from the details lists of both product pages.
| Product | Contents | Size | Yield | Dosage | Base water | Effect in the cup |
|---|---|---|---|---|---|---|
| APAX LAB Box Set | TONIK, JAMM and LYLAC | 3 × 100 ml | approx. 150 brews per bottle | 3 to 4 g/L or 1 to 10 drops per 200 ml | demineralised or soft, under 30 ppm | acidity, sweetness or clarity, depending on the concentrate |
| APAX LAB KONFLUX | one concentrate | 100 ml | approx. 150 brews per bottle | 3 to 4 g/L or 1 to 10 drops per 200 ml | demineralised or soft | mouthfeel, depth and sweetness |
How to test what water does
Water is one of several variables. To really taste what a concentrate does, keep everything else constant: the same beans, the same grind size and the same recipe, for example with the Graycano Dripper and the Filter GC01. Then brew two cups with different water and taste them side by side. You can record the recipe and your impressions of both brews in the Brew Lab.
Where brewing water fits in the setup and what comes before it is covered in the pour over setup in three steps.
