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

In the latest video from coffee enthusiast and creator Lance, he dives deep into the world of espresso preparation, specifically focusing on various distribution methods. If you’ve ever wondered about the best way to prepare espresso, this video is a must-watch. However, if you’re short on time, we’ve summarized the key points for you, so you don’t have to watch the entire thing.

Overview of the Video

Lance begins by addressing feedback from his previous video, where he tested different espresso distribution methods. He acknowledges the critiques regarding sample size and the equipment used, particularly the EG1 grinder, which may not reflect the average home experience. To address these concerns, he conducts a new series of tests using the DF64 Gen 2 grinder, focusing on direct-to-portafilter grinding.

Throughout the video, Lance explores five different espresso preparation methods: horizontal tapping, NCD (Naked Coffee Distribution), the blind shaker, WDT (Weiss Distribution Technique), and the autocomb. He meticulously details his process, including the use of a gravimetric feature on his espresso machine to ensure precision in his shots.

Key Findings

1. Direct-to-Portafilter vs. Dosing: Lance finds that grinding directly into the portafilter may lead to less consistent results compared to dosing into a separate container first. This is particularly evident when using the blind shaker method, which consistently yields higher extraction rates.

2. Densification Hypothesis: A significant part of the discussion revolves around the concept of densification. Lance theorizes that the shaking process during the blind shaker method allows finer particles to fill the gaps between larger particles, leading to a more uniform puck and better extraction.

3. Statistical Analysis: Collaborating with a statistician, Lance presents data showing that the blind shaker method outperforms others in terms of consistency and extraction yield. The results indicate a 99% confidence interval in favor of the blind shaker.

4. Temperature Stability: He emphasizes the importance of temperature stability during the grinding process, noting that overheating can skew results. Using larger grinders helps maintain consistent temperatures.

5. Practical Tips: Lance shares actionable steps for home baristas, such as experimenting with different shaking times to see how it affects extraction and flavor.

Key Takeaways

• Blind Shaker Method: This method appears to provide the best consistency and extraction yield compared to other techniques.
• Densification: The process of densification during shaking may improve espresso puck quality, leading to better extraction.
• Direct-to-Portafilter: Grinding directly into the portafilter may not yield the best results; consider dosing into a separate container first.
• Experimentation: Try varying shaking times to find the optimal method for your espresso preparation.

In conclusion, Lance’s video is a treasure trove of insights for anyone looking to refine their espresso-making skills. By summarizing his findings, we hope to inspire you to experiment with these methods and discover what works best for your taste preferences. Happy brewing!
