For two years, Gagné scoured academic literature, conducted dozens of experiments, and analyzed data from thousands of individual brews. He didn't just look at how long the water took to drain; he studied:

Pour twice the coffee mass in water (e.g., 30g coffee → 60g water). Wait 30–45 seconds. You’ll see the crust crack—that’s CO₂ releasing. Only then pour the rest.
