View this post on Instagram. A post shared by Stream .The early Atago iteration of the coffee refractometer you mention was developed while VST was consulting for George Howell Coffee Co before they spun off the refractometer/software line to VST. Dave May 1, 2015 | Reply The 1/(1-C) factor on the right-hand side of the equation has a very small effect on the calculated extraction yield for filter coffee, typically smaller between 0.2% and 0.4%.What this term represents intuitively is the contribution of extracted coffee mass to the beverage weight, so it is more important when C is high.. The equation above is useful if you know the liquid .
Before the prevalence of refractometers, a common response was to increase the dose. Although this will result in a stronger (i.e. more concentrated) cup of coffee, it actually lowers the extraction percentage. The final brew is stronger, but less of the coffee used was extracted. So how are coffee professionals using refractometers? “The R2 Extract is a professional-grade refractometer that detects how much coffee solids have been dissolved into the water and gives a readout. Whether you’re a barista looking to maximise consistency day-to-day, or a home brewer looking to brew the best possible coffee, the R2 Extract caters for every coffee aficionado,” Joe says. The aim of this study was to suggest we don’t have a good understanding of how refractometers characterize coffee extraction. I suspect such characterization was originally done on longer brews and didn’t consider that the bean is not homogenous. When calculating the conversion from refractive index to TDS, the input of output ratio is not .
Alternatively, TDS is best used to determine hot coffee extraction calibrations in a commercial setting. Optical Brix refractometers are relatively affordable, while digital refractometers used by coffee professionals average around 0. That said, they are an invaluable tool in calculating TDS and extraction percentages in brewed coffee.
