认识 DiFluid

DiFluid 由 Linus Peng 创立。他从南方科技大学博士项目退学创业，怀着一个简单却远大的想法：让每一个有好奇心的人，都能用上实验室级的精度。当个人、小型烘焙商和独立咖啡馆也能测量并分享与大品牌同等质量的数据，整个行业就会学得更快。

Our story

From many liquids to one cup of coffee

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.

生态系统

咖啡数据在整条价值链上四分五裂。种植者、进口商、出口商、烘焙师、咖啡馆老板、咖啡师和消费者各自使用不同的平台、工具和方法，让标准化变得极其困难。

DiFluid 希望通过一条由互联硬件组成的垂直链条和一套强大的操作系统来解决这个问题。

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.
