DiFluid’s Moment thermometer turns coffee cooling into guided tasting

DiFluid is trying to turn the last few degrees of a cooling cup into a sales tool for cafés. The company showed off Moment, a non-contact beverage thermometer, at World of Coffee San Diego, and says it plans a worldwide launch later this spring.

The device is built around a touchless infrared sensor that reads the drink’s surface temperature while a cup cools. As the thermal stage changes, Moment displays tasting notes on a color screen, mapping how aroma, clarity and finish shift from hot to warm to cool. The pitch is simple but ambitious: coffee does not taste the same at every temperature, and Moment is meant to make that progression visible to the guest instead of leaving it to a barista’s explanation.

DiFluid has also tied the tasting experience to its software stack. Customer reactions can be captured in the moment, with a tap for what a drinker liked and a long press for a broader rating that feeds into CoffeeOS. The company says CoffeeOS links farming, roasting, brewing and retail in a single platform, which puts Moment in the middle of a larger data loop rather than as a standalone gadget. In the Specialty Coffee Association’s Best New Product entry, the system is described as a way to help baristas and coffee professionals understand, present and share optimal tasting moments in every cup.

That hospitality angle is what makes Moment more interesting than a novelty thermometer. Ben Barnard, DiFluid’s program manager, said the product is especially useful in a busy shop where staff do not have time for one-on-one tasting guidance. DiFluid also describes it as barista-grade and says it runs for 12 hours on a charge, suggesting it is meant to stay on the counter through a full café shift. The question for shops is whether that guided tasting deepens appreciation enough to justify the extra step, or whether it risks adding friction to service.

The company’s booth placement in San Diego signaled how central the product is to that bet. World of Coffee San Diego ran April 10-12 and drew more than 17,000 visitors over three days, giving DiFluid a crowded stage for a tool aimed at cafés, tasting rooms and competitions. Moment also fits DiFluid’s recent product arc, following the Brew Control System in 2023, the Omix analyzer in 2024 and the AirWave purifier in 2025. Taken together, the launch suggests DiFluid is pushing beyond measurement and into the guest experience, where the real test will be whether a cup of coffee feels more memorable as it cools.
