Elevating Coffee Flavour Without Flavouring
When you hear about a product that "enhances coffee flavours," it’s easy to picture syrups, infusions, or flavour additives. APAX LAB mineral concentrates are anything but. Our approach doesn’t involve adding tastes to your coffee—instead, we focus on the role minerals play in shaping how you perceive the natural flavours of your brew.
Here’s the key distinction: APAX LAB is not a flavouring product. You can’t taste APAX in plain water. Instead, these mineral concentrates are designed to influence the way your palate interprets the existing flavours of coffee, unlocking its fullest potential.

What Makes APAX LAB Unique?
APAX LAB mineral concentrates — TONIK, JAMM, and LYLAC — are formulated to create specific water profiles that subtly alter how coffee flavours are perceived. By changing the mineral balance of your brewing water, they enhance different aspects of the coffee, such as sweetness, acidity, or floral notes.
It’s important to emphasise that these products work with your coffee’s inherent qualities rather than introducing any new flavour. This makes APAX LAB an entirely new kind of tool for coffee enthusiasts and professionals alike.
How Minerals Shape Flavour Perception
Minerals don’t add taste, but they play a critical role in how you experience flavour. Scientific studies have shown that chloride ions enhance sweetness perception, while magnesium and calcium ions can amplify acidity or smoothness, depending on their ratios.
For example, a study published in the journal Food Quality and Preference (2015) found that water with higher chloride content made beverages taste sweeter without altering their chemical composition. Another study from the Journal of Sensory Studies (2018) highlighted how mineral composition in water could significantly influence taste perception, even among trained sensory panellists.
APAX LAB mineral concentrates leverage this science to craft water profiles that emphasise specific flavour characteristics in coffee.
Not a Flavouring Product
Unlike flavouring products, which add distinct tastes like vanilla or hazelnut, APAX LAB concentrates do not leave any detectable taste in plain water. This is why you can’t taste TONIK, JAMM, or LYLAC when diluted in water.
Think of APAX LAB as a filter for your palate:
- A filter doesn’t add colour or texture to what you see—it sharpens your view.
- Similarly, APAX LAB helps you experience coffee flavours more vividly by enhancing your perception of its natural elements.
This approach respects the integrity of the coffee and ensures that every cup reflects the beans’ true potential.

Endorsed and Trusted by Coffee Champions
APAX LAB is not just a tool for experimentation; it has become a daily essential for some of the most prestigious figures and cafés in the coffee industry. Martin Wolfl, the current World Brewers Cup Champion, uses APAX LAB daily to elevate his coffee experience.
Additionally, Carlos Medina (2023 World Brewers Cup Champion), Shih Yuan Hsu (Sherry) (2022 World Brewers Cup Champion), Matt Winton (2021 World Brewers Cup Champion), and Tetsu Kasuya (2016 World Brewers Cup Champion) incorporate APAX LAB into their daily brewing practices. Their continued use of APAX underscores its reliability and transformative potential for both competitions and everyday brewing.
Backed by Science, Proven by Taste
The science behind APAX LAB is as compelling as the results it delivers. Studies on water chemistry and taste perception have consistently demonstrated the critical role minerals play in enhancing how we experience flavour. For example:
- A study in Food Chemistry (2021) highlighted how mineral interactions can enhance sweetness perception without altering the chemical profile of the beverage.
- Research from the International Journal of Sensory Science (2017) underscored how magnesium and calcium ratios influence taste clarity and overall balance in beverages.
APAX LAB’s formulations are the result of years of meticulous research and development, led by Simon Gautherin, a Q Arabica Grader and Head of Training and Education at Zest Coffee. With over 10 years of experience in the specialty coffee industry, Simon has crafted these mineral profiles to bring out the best in every cup.
Moreover, APAX LAB is trusted by some of the world’s most prestigious cafés, as well as national and world champions, to consistently deliver exceptional flavour experiences.
