BEST WAY TO PREP ESPRESSO?: The Finale (WDT, WW Blind Shaker, Autocomb, NCD)

The video compares different espresso distribution methods, including horizontal tapping, NCD, blind shaker, WDT, and autocomb. The blind shaker method performed the best in terms of consistency and extraction yield, potentially due to densification of grounds. Direct to porta filter dosing was found to be better than dosing from a separate container. The blind shaker showed quicker extraction times and higher yields. The autocomb method performed similarly to the blind shaker. Densification may help improve extraction by reducing resistance in the puck. Collaboration with statisticians and scientists helped analyze the data. The video concludes that direct to porta filter dosing and densification may lead to better espresso results. The blind shaker method was recommended for improved consistency and extraction yield. Unique points mentioned include the use of a cheaper grinder, collaboration with experts, and the potential benefits of densification in espresso preparation.
