APAX LAB Signature Mineral Concentrates - Transform Your Coffee’s Flavour with Just a Few Drops

Brew Like a Champion

The APAX LAB mineral concentrates — TONIK, JAMM, LYLAC & KONFLUX - are designed and crafted for you to season your water to allow you to unlock the true core of your specialty coffee, just as the roaster wants you to experience. Created for baristas, cafés, competitors, and curious home brewers, this set gives you the freedom to explore how each mineral profile transforms flavour, balance, and texture in every cup.

Trusted and used by 90 % of competitors at the 2025 World Brewers Cup, this is the ultimate toolkit for championship-level brewing and everyday experimentation alike.
