$ULTIMATE COFFEE REFRACTOMETER SHOWDOWN (Plus Methodology and Best Practices) Refractometer best practices, explanation of TDS and EY, and a refractometer showdown. What more can you want as a coffee nerd? Why is the VST my baseline? Here is an independent study showing the VST is at most at .03% accuracy vs. over drying: https://www.nature.com/articles/s41598-021-85787-1 Scroll to the supplementary info and see Supp Fig 3!

Please consider subscribing if you have yet to do so. Every bit of interaction helps fuel both this channel monetarily but myself motivationally. Thank you Jonathan Gagne for the help creating the graphs and to my discord for giving me some company while brewing and measuring. Find data and graphs here- https://www.dropbox.com/sh/yonpqn2cmauzkpu/AADJiL6rypTTz_X8lXqz3RUMa?dl=0 QUICK NOTE- I actually took 10 samples of espresso, not 5. I did 5 more after filming to match the 10 for filter. If youd like to BUY an Atago or Difluid, please consider using the following links if and only if you are planning on using amazon. Personally, I would prefer you find another means to obtain these pieces of equipment, if you are going this route, Id appreciate taking a bite out of their apple. I get a small commission on any purchases made with them. I also have an amazon storefront wherein you can buy most anything through it and Ill receive some kickback. Again, only if you arent able to find them at local shops or reputable resellers. Thanks!
