Redefining Water for Coffee.
At APAX LAB, we create precision mineral concentrates that unlock clarity, sweetness, and balance in every cup to help you reach coffee climax — trusted from the world championship stage to cafés worldwide.
Who We Are
Born from years of research into the chemistry of water and its impact on coffee brewing, APAX LAB was founded in 2024 to bridge the gap between competition-level precision and everyday usability. What started as a vision to give baristas more control has grown into a global movement, reshaping how water is understood and used in coffee.
"APAX," inspired by the term 'apex', manifests our dedication to reaching the utmost standards in all our endeavours. Our products are the result of this philosophy, each with its own special touch that makes it distinctly APAX LAB.
Our mineral concentrates were created by Simon Gautherin, following 6 years of deep research, testing over 2000 recipes and collecting an immense amount of data to bring these perfectly balanced profiles to life.
APAX LAB was born out of a desire to reach higher heights and push the boundaries of exceptional coffee.


We believe in pushing the boundaries of exceptional coffee by transforming water into the most precise brewing tool.
- Innovation - Always question the status quo and never settle into our comfort zone.
- Excellence - Develop products with utmost standards and that truly make a difference.
