Key ideas in Precision Espresso Extraction
- Tapered basket walls force peripheral water toward the center, whereas straight-walled baskets yield uniform vertical paths right to the edge
- Tamping past the point of mechanical bed consolidation does not alter extraction flow dynamics or fix boundary-layer bypass
- Edge-to-center hole coverage density directly dictates whether peripheral water finds a clear exit or stagnates
- Sudden hydraulic shock dislodges loose microscopic fines and carries them downward before the bed can swell
- Migrated fines blind individual exit apertures, spiking localized resistance and forcing high-velocity micro-channels adjacent to blocked holes
- Gentle pre-infusion allows the bed to saturate and swell, trapping fines in place within the matrix
- Under-puck paper filters physically block fines from wedging into the metal basket holes, preventing aperture clogging
- Lower exit-hole resistance allows the barista to grind substantially finer, boosting surface area contact and extraction yield without choking the machine
- Paper filters promote edge-to-edge flow across the bottom plane rather than forcing flow to funnel into discrete metal apertures
- Insufficient headspace physically cramps puck expansion against the dispersion screen, preventing uniform water infiltration
- Excessive headspace creates a deep water column over the puck that delays pressure building and causes bed erosion from turbulent surface pooling
- Proper clearance allows the bed to gently swell 1-2 mm upward during pre-wetting before being subjected to full extraction pressure
- High-flow precision baskets have higher total open area (TOA) right up to the wall, radically decreasing base exit resistance
- Baristas must grind significantly finer or throttle water flow/pressure during the main extraction phase to generate adequate contact time
- Maintaining standard grinds in high-flow baskets results in rapid run-through, uneven periphery flushing, and harsh, astringent underextraction
- Dense light roasts wet slowly and resist water penetration compared to porous dark roasts

One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Precision Espresso Extraction the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
If you notice water slipping around the edges of the basket, what happens when you tamp with 50 pounds of force instead of 30?
