6 Bar vs 9 Bar: The Impact on Espresso

Again, this video is just demonstrating the results of my own testing in a controlled environment with lighter roasted coffees. As a TLDW, there was no statistically significant differences from 90-99% confidence intervals on the extraction and tasting was random when pulled in traditional parameters. The only difference was with the washed Ethiopia where more turbo-style shots were pulled, wherein the bar threshold was not able to be held static, introducing other variables. All of the data and taste results are below. For the Qaroro- I voted 6 bar thrice and 9 bar twice. Rui voted 6 bar twice and 9 bar thrice. For the Leona Tabi- Rui and I were perfectly calibrated and both voted 6 bar twice and 9 bar thrice. For the Alaka- We both chose 9 bar for all 5.
