DiFluid started out with a fairly simple question: How can digital refraction technology be improved in the internet age, with the power of a smartphone? This new refractometry method produced a significantly faster, more stable, and more accurate device than any of its predecessors could. Since then, DiFluid's been hard at work developing and fine-tuning new technology aimed at measuring extraction for brewing coffee with unparalleled precision. Moreover, the company is specifically set on putting a device that was once available only as an expensive piece of lab equipment into the hands of the average consumer. They are also starting to build a range of complementary accessories. You can explore what's available in South Africa, below.
