Apax Lab Box Set – three water profiles to discover
Same bean, same machine, same settings – and yet every cup tastes different depending on the water behind it.
The Apax Lab Box Set combines the three mineral concentrates Tonik, Jamm and Lylac. With them, you build your own brew water and decide whether your coffee turns out clear and fruity, round and sweet, or delicate and floral.
Three profiles, three directions
Tonik emphasises the lively character – clear, crisp, fruity. Jamm brings fullness and sweetness, a creamy mouthfeel. Lylac highlights the delicate, floral notes, with a silky finish. Water is the solvent of extraction: minerals like magnesium bring out fruity and floral aromas, calcium adds body, bicarbonate provides balance. The direction is up to you.
How to Use It
Add a few drops directly to the cup, or mix around 3 to 4 grams of concentrate per litre into demineralised water. Recipes and a calculator are available from Apax Lab. Feel free to combine the profiles to find your own recipe. There's no right or wrong – the coffee has to taste good to you.
Apax Lab produces its concentrates from demineralised water and analytical-grade reagents. Our opinion is one of many.

What Goes Well With It
Water is the foundation: we show you how to compose it yourself on the page Composing Your Own Coffee Water. As a pure starting base, demineralised or filtered water works well – you'll find filters in the Brita Collection. And the profile only really unfolds with fresh coffee from our coffee beans.
Frequently Asked Questions
What's included in the Box Set?
Three mineral concentrates – Tonik (clarity, fruitiness), Jamm (body, sweetness) and Lylac (floral notes) – in 20 ml each.
Do I need demineralised water?
For a full recipe, yes: a mineral-free base (demineralised or via reverse osmosis) makes dosing predictable. Alternatively, you can add a few drops directly to the finished cup.
How do I dose it?
A few drops per cup, or around 3 to 4 grams of concentrate per litre of water. Recipes and a calculator are available from Apax Lab.
Can I mix the profiles?
Yes. Tonik, Jamm and Lylac can be combined until your water matches the bean and your taste.
Can I see the set before buying?
Of course. In our showrooms in Bern (Gerberngasse 44) and Zürich Oerlikon (Hagenholzstrasse 50b). Delivery throughout Switzerland and to Liechtenstein in 2 to 4 working days.
Roastery Tip
Profile meets bean: a clear, fruity profile draws out the peach note in our Wild Peach roast, while a body-forward profile makes our Cozy Chocolate or Nutty Delight even rounder. For maximum body, go for the Very Nutty. That's our recommendation – one of many.
