Lance Hedrick admits Reddit was right about grinding espresso finer

For years, the online coffee community r/espresso repeated a singular mantra to every struggling home barista: grind finer. Coffee educator Lance Hedrick spent years fighting this dogma. Yet, looking closely at beginner struggles reveals why this simplistic advice persists. Beginners often chase a specific, dark-roasted, thick-bodied shot. For that classic style, increasing physical resistance in the basket is exactly what is needed.

The structural perils of grinding too fine

Pushing the grind size too tight introduces mechanical chaos. Extremely fine particles create immense physical resistance. This forces the pressurized water to find paths of least resistance, leading to channeling and uneven, heterogeneous extraction. Your grinder works harder, generating excess friction and heat during the process. The method demands flawless puck preparation to avoid bitter, hollow cups.

Beginner expectations versus enthusiast experimentation

The divide lies in intent. Beginners want the classic 1:2 ratio pulled in 30 seconds with a rich crema. Grinding finer delivers this visual ideal. Enthusiasts, however, often brew incredibly light roasts. For these delicate beans, grinding coarser and allowing a faster flow rate—even a fast shot finishing in 12 seconds—extracts bright, clear flavors without harsh bitterness.

Shedding dogma for a better cup

Ultimately, technique must serve the bean and the brewer's preference. Rigidly clinging to a single extraction rule limits your culinary palate. Whether you prefer a traditional syrupy shot or a fast, modern, high-clarity extraction, taste remains the final arbiter. Master the mechanics, understand your variables, and adjust the grind to match your specific coffee beans rather than a forum meme.
