By: Robert, Joe, and Jeremy. DiFluid originally came out with a small, affordable refractometer earlier this year. The accuracy by a few studies suggested the device may perform well enough for some coffee, but concerns increased as signal strength decreased in a sample (i.e. filter strength coffee). Even more troubling was the manufacturing variance across devices. Espresso: Espresso requires a higher TDS to achieve the desired strength and richness. The recommended TDS range for espresso falls between 18% and 22%. French Press: French press brewing typically results in a higher TDS due to the longer extraction time. A TDS range of 1.35% to 1.45% is commonly recommended for French press coffee.
