APAX Lab Mineral Concentrates Box Set

Transform Your Coffee’s Flavour with just a Few Drops

The APAX LAB Box Set brings together three mineral concentrates: TONIK, JAMM, and LYLAC. Designed for baristas, cafés, competitors, and curious coffee lovers, it gives you the freedom to explore how each profile transforms flavour, balance, and texture in the cup.

• Unlocks clarity, sweetness, body, and elegance in your brews.

• Provides all three mineral profiles to experiment and pair with different coffees

• Perfect for home brewers wanting to learn, and cafés looking to refine flavour for every origin, and coffee competitors.

• Compact format ideal for training, education, and travel.

We are now using APAX Labs mineral concentrates at Coffee Embassy Cellar Door and roastery to elevate the cup profile of our batch brew and pour over coffees. Our Head of Coffee James has provided some recipes designed as a starting point for using these drops below.

Water Recipes

Your brewing water can make or break whether a coffee tastes vibrant and expressive or flat and muted. Since local water supplies vary, we’ve partnered with Apax Lab to help optimise your home brewing water.

The following recipes are designed as starting points, focusing on clarity and even extraction to let the coffee’s natural acidity and sweetness shine.

For the Low-Key Approach

Base Water: Christchurch tap water

• Hardness (GH): 45ppm

• Alkalinity (KH): 52ppm

Apax Drops per 1L:

• Tonik: 10 drops

• Jamm: 5 drops

Since the alkalinity is already relatively high, Lilac is not needed, as alkalinity naturally buffers acidity. Instead, we focus on Tonik to increase hardness for improved extraction and Jamm to enhance texture, helping round out the cup.

For the Coffee Geek

Base Water: Fully distilled water (<1ppm TDS)

Apax Drops per 1L:

• Tonik: 30 drops

• Jamm: 5 drops

• Lilac: 10 drops

This recipe provides a balanced foundation that can be adjusted further depending on your taste preferences and the coffee being brewed.

If you are outside of Christchurch, we recommend using the distilled water recipe. 

Always add to the water before brewing - not the brewed coffee. 

If you need assistance or are simply curious about the Apax drops, our Head of Coffee, James, welcomes all enquiries. You can get in touch at james@coffeeembassy.co.nz.
