Hello Mat, I know that is not a standard magical number. But, for v60 brewing where the TDS should be ? like a taste good statistical range?

Great video, but I'm confused by the use of the filter. If you want to measure the solids in the coffee, doesn't the filter remove some of those solids and affect the accuracy of the measurement?

you want to measure dissolved solids, not fines

Darren is right. Here's my problem with this. Lipids (oils) are technically insoluble, but end up in the brewed coffee anyway as a sort of colloidal suspension. That absolutely constitutes some mass that was extracted from the coffee. If we use TDS (which shouldn't just be *solids* and not everything is necessarily *dissolved*) to figure extraction percentage, our extraction percentage is going to be inaccurate if we start filtering out oils. Fines I can understand filtering out, as we don't intend to get them through the filter. But oils definitely need to be accounted for.

Can I filter espresso with v60 paper??! Or syringe filters is necessary?!!

Matt I just finished doing the drip method using your technique and you are a genius my friend.. how come you dont have videos on Siphon and other methods, there are only 2 videos!

Hello Mr. Perger, would you approach measuring the TDS with espressos the same way? If not, how? Thank you very much in advance!

Of course man, TDS is just the total dissolved solids, the spectrum includes both espresso and filter. as long as you filter it before hand you should be all set :)

Nice informative video. Nonetheless, I am wondering whether the syringe filters are to be used also with filtered brewing methods which obviously hold back all undissolved solids: pourover cones (V60, Kalita Wave...), Chemex, Syphon pot, Clever Dripper? I thought that only espresso, French press, AeroPress, Turkish coffee and cupping needed them. Further questions: is it possible to re-use the pipettes - and if so, how many times - or are they designed to be disposed of after every single use? Same question for the syringes. And finally, this one: in the video, it's written we can re-use the filters up to 2 espressos or 5 filter coffee samples, while in the description section you advise against re-using the filters to prevent inaccurate readings. So, what about the re-using of those syringes filters? Please, enlighten me. Thanks!

In the instruction manual they say the Filters should be used to filter non-dissolved solids and to degas CO² out of the espresso or freshly roasted coffee for pour overs. You should use them if you have to degas fresh coffee/espresso or if you used a metal-filter, Aeropress or czesve for turkish coffee, because this kind of brews includes more non-dissolved solids which can lower the refractive index, while the CO²-gases will increase the refractive index. The filters should be used only once. Any dilution, whether via a new coffee sample or water effectively contaminates the new sample and any such measurement will be invalid. The Refractometer comes with ten 1ml transfer pipettes. I re-use them atm, using hot water to wash out the coffee from them and using one pipette only for the calibration water. I'm not sure if this effects the measured TDS%. If not I'd use glass pipettes instead of the disposable transfer pipettes, but if, then I have to buy and waste a lot of pipettes. Atm I don't have destilled water, so I use my brewing-water (before heating) for calibration. This might make the measurements more inaccurate, or gives me a lower tds% as it should be, based on the TDS in the water. Otherwise I've read somewhere, someone says he uses his brewing water too, so the Refractometer doesn't count the TDS of the water. It's like tare the TDS of the water.

I found some answers on the question why you should use destilled water for calibration in the comments section at Chris bacas video about refractometers: kzitem.info/news/bejne/06Np3JlunZV2q4Y Also someone sayd It's better to wipe the destilled water with kimwipes and don't use alcohol pads after that, because the alcohol pads could contaminate the lens too. I still found no answer on reusing the pipettes, but I think It's saver only use them once. Also this article from Socratic Coffee is interesting about using or not using filters, because they will change the results: socraticcoffee.com/2016/02/examining-the-impact-of-particulate-matter-in-refractometry-for-coffee-assessment/
