Wer ist DiFluid

DiFluid wurde von Linus Peng gegründet, einem Unternehmer, der sein Promotionsstudium an der Southern University of Science and Technology abbrach, um eine einfache, aber ehrgeizige Idee zu verfolgen: Präzision auf Laborniveau in die Hände aller zu legen, die neugierig genug sind, sie zu nutzen. Wenn Einzelpersonen, kleine Röster und unabhängige Cafés Daten in derselben Qualität messen und teilen können wie die Großen der Branche, lernt die ganze Branche schneller.

Our story

From many liquids to one cup of coffee

Measuring TDS with DiFluid R1

Digitize Fluid

In 2021, Linus built R1 to read many liquids: fruit juice, honey, milk, coffee, even wastewater. DiFluid wasn't a coffee company yet. The name came from a much wider idea, Digitize Fluid: turn the changes you can't see inside a liquid into numbers you can read and compare.

Linus was working on a PhD at Southern University of Science and Technology at the time. With a background in electronics, optics and physics, he noticed something that didn't add up. Refractometers had been around for decades, yet the technology inside them, and the experience of using one, had barely moved. Buyers were stuck choosing between a high price, limited precision and awkward handling. He knew it could be done better, and built R1.

Where measuring matters most

A better device settled how to measure. It left open where measuring mattered most, so Linus went looking across liquids. Fruit was one of R1's first big uses. With a reading of 5% or 14% soluble solids, you know right away: not sweet, or sweet. Useful, and simple.

Coffee was different. Its TDS moves within a narrow range, yet a small shift changes the cup. Concentration, extraction, grind size, water temperature and brew method all pull on each other, so one reading starts more questions instead of settling them. Why do the same beans taste so different? Which step caused it? Can a great brew be understood, compared and made again?

Of everyone using R1, coffee people asked the most questions, and the hardest ones. Their curiosity kept pulling Linus back to coffee, to study how devices, data and taste connect.

Depth over breadth

Linus didn't drink coffee then. What drew him in was how hard its problems were. Over time he saw that measuring more kinds of liquid mattered less than understanding one liquid deeply.

In 2022, DiFluid released R2 Extract, built entirely for coffee. It was more than the next generation of R1. It was a decision: stop making a tool for every liquid, and build a complete way to measure concentration, extraction and brewing. Microbalance followed the same year, taking DiFluid from the result in the cup to the brew that produces it. By the time Omni arrived in 2023, there was no doubt where DiFluid was headed.

For several years, Linus ran his PhD and the company side by side. He left university only once the products, the users and the direction had all proven themselves.

What coffee gave back

Coffee changed Linus too. The founder who didn't drink it became a devoted coffee lover. Through DiFluid he met coffee professionals and friends around the world, and in cafés from city to city he tasted countless ideas of what coffee can be.

DiFluid's direction was never fully written at the start. It was there in the first R1, in the questions users kept asking, and in the moment Linus chose depth over breadth.

Das Ökosystem

Kaffeedaten sind entlang der Wertschöpfungskette zersplittert. Farmer, Importeure, Exporteure, Röster, Cafébesitzer, Baristas und Konsumenten nutzen unterschiedliche Plattformen, Werkzeuge und Methoden, was eine Standardisierung extrem schwierig macht.

DiFluid will das mit einer vertikalen Kette vernetzter Hardware und einem robusten Betriebssystem ändern.

Measure for clues. Taste to decide.

A cup of coffee is shaped by origin, roasting, grinding, water, equipment, environment and brew method. Through years of tasting and practice, coffee professionals learn how each one shows in the cup. Yet much of what matters can't be seen, and hard-won experience is difficult to record, compare and pass on.

A number means something only next to the conditions, the process and the taste behind it. Each DiFluid device makes one part of coffee visible: concentration, extraction, particle size, roast color, moisture, temperature. CoffeeOS connects them, so every measurement, tasting and brew becomes something you can compare, share and build on.

We don't decide what good coffee is for you, and we don't replace tasting with data. Whether you're a barista, a roaster or simply curious, DiFluid helps you see what changed, ask sharper questions and trust your own palate.

Die Hardware

DiFluid hat Hardware für den gesamten Weg des Kaffees entwickelt: von der Messung von Feuchtigkeit, Wasseraktivität, Dichte und Siebgröße für Farmer und Röster über die Live- und statische Messung der Röstfarbe und die Rauchbeseitigung für Röster bis hin zur Partikelgrößenanalyse und zu Tools für die Brühkonzentration für Baristas. Und das ist erst der Anfang. Zahlreiche neue Produkte sind in Entwicklung, und alles, was DiFluid baut, läuft auf einer gemeinsamen Plattform: CoffeeOS.

Was ist CoffeeOS?

CoffeeOS ist eine eigene Plattform, die jede Station auf dem Weg des Kaffees verbindet, von der Farm bis in die Tasse. Es arbeitet nahtlos mit dem wachsenden Hardware-Ökosystem von DiFluid zusammen und vereint alle Tools, Messungen und Erkenntnisse in einer App. Es ist nicht nur eine Begleit-App, sondern ein Betriebssystem für Kaffee.

R1 gave liquids a language of numbers. Coffee gave those numbers meaning.

Coffee, understood.
