APAX LAB Box Set – The Ultimate Tool for Coffee Optimization

APAX LAB Box Set – The Ultimate Tool for Coffee Optimization

Transform your coffee's flavor profile with just a few drops. The APAX LAB Box Set combines all three of APAX LAB's signature mineral concentrates – TONIK, JAMM, and LYLAC – into one complete package. The set is designed for ambitious home baristas, cafés, roasters, and competition enthusiasts, giving you full freedom to explore how different mineral profiles radically change taste, balance, and texture in the cup.

Water makes up 98% of a finished cup of coffee, making it the very foundation of the flavor experience. APAX LAB does not change the coffee beans but rather the way your palate perceives the coffee's natural flavor notes. The set is approved and used by up to 90% of participants (including 8 out of 9 finalists) at the 2025 World Brewers Cup, making it the ultimate tool for both everyday coffee experiments and championship-level brewing.

Why choose the APAX LAB Box Set?

Unlock full potential: Experience unmatched clarity, sweetness, body, and elegance in your brews.
Three unique mineral profiles: Includes all three signature profiles so you can experiment and precisely match different beans, origins, and roast profiles.
Versatile and educational: Perfect for the coffee lover who wants to learn about the importance of water or the café that wants to fine-tune flavor for each coffee's origin.

Compact and travel-friendly: The ideal format for flavor training, education, and when you want to geek out on coffee on the go.

Explore the three profiles:

1. TONIK – Lively, fresh & juicy (Vibrant, bright, juicy) 

Formulated to highlight the coffee's lively acidity and give a crisp, juicy, and intense kick to your brew. TONIK increases clarity and fruit notes, making especially washed coffees and fresh, fruit-driven profiles shine.

• Tip: TONIK can slightly reduce perceived body to instead let the fresh acidity and juiciness come fully forward.

Ingredients: Water, magnesium chloride, calcium chloride, sodium chloride, sodium bicarbonate, potassium bicarbonate.

2. JAMM – Rich, sweet & creamy (Rich, sweet, creamy) 

JAMM enhances the role of calcium and bicarbonate in water. The profile is developed to give coffee more richness, depth, and roundness, as well as highlight lingering sweetness and a creamy mouthfeel. It is perfect for balancing coffees with very pronounced or experimental fermentations, wilder berry notes, and heavy, full-bodied profiles.

Ingredients: Water, magnesium chloride, calcium chloride, potassium chloride, potassium bicarbonate, sodium bicarbonate.

3. LYLAC – Elegant, floral & silky (Elegant, floral, silky) 

LYLAC leverages the qualities of sulfate and potassium to emphasize the delicate and floral characteristics in your coffee. It refines texture, reduces dryness/astringency in light roast profiles, and leaves an elegant, refined cup with a silky mouthfeel and a long, clean aftertaste. Especially suitable for high-quality Ethiopian coffees or Gesha varieties.

Ingredients: Water, magnesium sulfate, magnesium chloride, potassium chloride, potassium bicarbonate, sodium bicarbonate, sodium chloride.

The science behind it: "Spice" for your coffee (No artificial flavor)

When a product is described as something that "enhances coffee flavor," many immediately think of syrups, infusions, or flavor additives. APAX LAB mineral concentrates are the exact opposite. It is not a flavor product, and you cannot taste TONIK, JAMM, or LYLAC at all when diluted in pure water.

Instead, APAX LAB acts as a "spice" for your brewing water – just like salt and pepper for food. The ultra-pure composition of the minerals changes the way your taste buds and palate perceive the coffee's existing, natural flavor compounds. For example, chloride ions enhance the perception of sweetness, while magnesium and calcium in the right ratios highlight acidity or mouthfeel respectively. You add nothing artificial – you simply sharpen your palate's perception and unlock the coffee bean's true potential.

How to use APAX LAB (Instructions)

No chemistry degree is needed to master APAX LAB. The set is incredibly easy and intuitive to use, and the concentrates can be used in two ways:

1. Shake the bottle well before use.
2. Pre-brewing (Adding to water): Start with demineralized, distilled, or very soft water (ideally under 30 ppm). Then add 3 to 4 grams of your chosen APAX LAB mineral concentrate per liter of water to build your brewing water from scratch.
3. Post-brewing (Directly in the cup): Add 1 to 10 drops directly into your finished brewed filter coffee or espresso (based on a standard cup of about 200 ml) and stir. Taste drop by drop!

Tip for your first experiment: Brew a cup of coffee with demineralized water and divide it into four small cups. Let one cup be a control cup without additives, and add a few drops of TONIK, JAMM, and LYLAC to the other three. This is the fastest and most fascinating way to taste the minerals' direct effect on the coffee's flavor profile!

Specifications and contents

• Bottle sizes: Available as either 20 ml (equivalent to about 30 brews) or 100 ml (equivalent to about 150 brews) bottles with precision pipette.
• Ultra-high purity: Made exclusively from demineralized water and chemically pure minerals of analytical reagent grade (AR Grade).
• Versatility: Suitable for filter coffee, espresso, and all milk-based coffees (try JAMM in a caffe latte or flat white!).
• Use in espresso machines: You can use a very small amount in the water tank (max 1 g/liter) to protect the machine's boiler from mineral deposits. For optimal safety and machine care, however, it is recommended to add the drops directly into the cup after extraction.
