A water chemistry starter kit for the brewer who wants to see how far three different minerals can take a cup

Every brew starts with water, and water is never just water. It carries minerals that shape how coffee extracts, how sweetness comes forward, and how a cup finishes. Most brewers never touch that variable, not because it doesn't matter, but because the tools to work with it usually feel like they belong in a lab, not a kitchen.

This starter kit is built for finding that out. It pairs the Apax Lab Water Mineral Concentrates, Nano Box Set, three concentrates named Tonik, Jamm, and Lylac, with an Apax Lab TDS Meter Pen, so you can measure your water, then try each mineral against the same beans and see what changes.

Water Customization Made Easy

Water chemistry has quietly become one of the more interesting frontiers in home brewing. Total dissolved solids, the minerals suspended in your water, influence how thoroughly coffee extracts and which flavors come through most clearly. Two brewers using the same beans, the same grinder, and the same recipe can land in different cups if their water differs.

Built for Exploration

The Nano Box Set is not a single fixed recipe. It holds three separate directions, made so you can taste the range rather than commit to one answer. Tonik, Jamm, and Lylac each push a cup somewhere different, and having all three on hand means a side-by-side comparison is only a few drops away. Brew the same coffee three ways, once with each concentrate, and the differences show up in the cup rather than on a spec sheet.

Why Water Chemistry Matters

The Apax Lab TDS Meter Pen measures conductivity, giving you a fast reading of your water's total dissolved solids before you start. That reading is your baseline, the fixed point you compare against as you test each of the three minerals from the Nano Box Set. Used together, the meter and the concentrates turn water into something you can actually investigate, one adjustment and one cup at a time.

Product Details

The Setup

The kit is built around a simple loop: measure, then explore. Start with the Apax Lab TDS Meter Pen to read your water's baseline. From there, add drops from the Nano Box Set, Tonik, Jamm, or Lylac, to shift your water and compare what each one does to the same brew. A use guide walks through starting ratios for each concentrate, and a downloadable recipe guide is included for brewers who want a proven starting point before branching out on their own.

What's in the Box

• Apax Lab Water Mineral Concentrates, Nano Box Set: Tonik, Jamm, and Lylac, 20ml each
• Apax Lab TDS Meter Pen: One meter for measuring total dissolved solids
• Use guide: Starting ratios and instructions for all three concentrates, plus access to a downloadable recipe guide

Created in collaboration with Nemo Pop, this limited-edition mineral concentrate replicates the exact water profile used during his world-winning routine. Designed to deliver a sweet, structured and velvety cup, this profile enhances mouthfeel while maintaining clarity and controlled acidity.

Developed during months of preparation and refinement, this recipe became the foundation of Nemo’s winning approach: a cup that feels round, balanced and expressive from the first sip to the finish.

What This Profile Brings

• Heavy, round mouthfeel
• Enhanced sweetness and balance
• Clear flavour definition
• Smooth, controlled acidity

The result is a cup profile that feels rich, sweet and structured, while still allowing the coffee’s origin character to shine.

Lucid [2.1] is a mineral concentrate developed to sharpen aromatic clarity and brightness in the brews of light roast coffee.

A light roast shows what it's made of in the details you can taste past the surface: the fruit, the florals, the fine acidity that either comes through clean or gets lost in translation. Water plays a larger part in that outcome than most brewers give it credit for. Lucid [2.1] is a mineral concentrate designed to work with a clean, expressive, bright roasting style, sharpening the aromatics and the finish rather than covering them up.

A Collaboration with APAX LAB

Lucid [2.1] was co-created with APAX LAB, an Australian company that designs high-precision mineral concentrates for coffee. Their work centers on isolating the mineral ratios that shape how aroma and acidity present in the cup, then concentrating them into a form that's simple to dose and easy to repeat.

Paired with TANAT's roasting approach, Lucid [2.1] was tuned to bring out what a bright, expressive light roast is built to show: clearer aromatics, elevated brightness, and a more refined finish. The result is a cup that reads as clean and precise, without asking the brewer to change anything else about how they already brew.

How to Use

Shake well  before use, so the concentrate is evenly mixed.

Dose per cup  add 1 to 2 drops to a cup of freshly brewed coffee, about 200 ml.

Water Remineralization

Lucid [2.1] can also be used to remineralize brewing water directly. Add it to distilled water at a rate of 1.5 to 2.5 grams per liter, ahead of brewing, for a version of the same clarity built into the water itself.

What's in the Box

Lucid [2.1] Mineral Concentrate x 1  bottle size TBC, confirm with supplier before publishing.

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

APAX LAB developed this mineral concentrate with specific challenge in mind: a profile that supports light roasts rather than working against them. The result is a cup with more brightness, better structure, and a clearer read on what the coffee is actually trying to say.

A Collaboration with MOK Coffee

This profile was created with MOK Coffee, a specialty roaster based in Brussels known for expressive light roasts and clean, precise flavor profiles. APAX LAB worked directly with MOK to build a mineral composition suited to the roasts MOK is known for: coffees where clarity and origin expression matter more than heavy body or roast character.

The goal was balance. Light roasts can taste thin or sharp when the water chemistry isn't dialed in, and they can taste flat when it's ignored altogether. This concentrate is formulated to sit in between, adding lift and structure without masking what the coffee already does well.

What This Profile Brings

• Brightness and lift: A more vibrant, lifted cup profile that lets acidity and florals come through cleanly.
• Balance and structure: Improved overall balance, with more definition between the coffee's different flavor layers.
• Texture and mouthfeel: Added body and mouthfeel, so a delicate cup doesn't taste thin.

How to Use

Shake the bottle thoroughly before use. Add 3 to 4g/L of mineral concentrate directly into your brew water, or add 1 to 10 drops directly into a 200mL cup of coffee, adjusting to taste. For the most control over remineralization, use demineralized water as your base.

What's in the Box

• MOK x APAX LAB Mineral Concentrate, 20mL bottle x 1

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

A mineral concentrate calibrated to match Terres de Café's coffees, drop by drop.

The water you brew with carries as much information as the coffee itself. Minerals shape how sweetness lands, how acidity resolves, and how texture sits on the palate, often before a coffee's own character gets a fair hearing. This concentrate was developed to close that gap, giving Terres de Café's coffees a water profile built specifically to draw out what's already in the cup.

A Collaboration in Precision

Terres de Café is a French specialty coffee roaster, known for refined sourcing, responsible agriculture, and coffees built around brightness, structured sweetness, and an elegant, coating mouthfeel. Matching that profile consistently depends on the water it's brewed with, which is what led to this collaboration with APAX LAB, a lab focused on precision water design for coffee.

The result is a concentrate developed specifically to match Terres de Café's coffees: engineered to reveal brightness, lift sweetness, and support a coating texture, so each coffee can express its full aromatic range. It functions less like a water treatment and more like a seasoning for coffee, giving you a tunable way to adjust the brew, whether that's mixed into your brewing water ahead of time or added straight into the cup.

What the Concentrate Brings

• Brightness and clarity: Lifts liveliness in the cup and sharpens the definition between flavor notes.
• Refined sweetness: Supports a rounder, more structured sweetness rather than a flat or thin one.
• Silky, coating mouthfeel: Adds body and texture that carries the coffee's flavor further across the palate.

How to Use

Shake the bottle thoroughly before use. Add the concentrate to your brew water at 3 to 4g per liter, or add it directly into a brewed cup: 1 to 10 drops per 200mL is the standard range. Demineralized water is recommended as the base, since it gives you the most control over the remineralization process. The concentrate is not intended for direct consumption on its own, and it should not be used inside espresso machines.

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