DiFluid R2 Extract Refractometer

In coffee analysis, a refractometer emerges as a crucial tool. This device gauges the concentration of dissolved solids (TDS) by measuring the refraction of light through a liquid. In simpler terms, it determines the coffee’s strength. With the TDS value in hand, computing the extraction yield becomes possible, reflecting how effectively the coffee grounds were utilized.

Coffee beans encompass around 30% soluble compounds, while the remainder consists of cellulose. Achieving an optimal extraction rate, ranging between 20% and 25%, is the key to unlocking the perfect brew.
