18 Nov 2022 --- DiFluid, a technology company founded by Linus Peng in Shenzhen, China, has launched a system that tailors a cup of coffee to the user’s preference. As part of the Brew Control System, Microbalance, a “precision smart” coffee scale, and its mobile app DiFluid Café, can help consistently brew a quality cup of coffee that is tailored to the consumer. It also uses R2 Extract, a professional-grade refractometer that detects how much coffee has been dissolved into the water and gives a readout.
