Advanced Coffee Extraction

Like Duolingo, but for Advanced Coffee Extraction. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Precision Dialing and Origin and Physics.

What you'll learn

Key ideas in Advanced Coffee Extraction

  • Acids and salts dissolve first
  • Tannins and polyphenols extract last
  • The sweet spot timing
  • Temperature and kinetic energy
  • Lower temperatures and acids
  • Light roasts and porosity
  • Mapping specific sensory defects
  • Applying temperature adjustments
  • Highly soluble acids and salts dominate the first 10-15% of the brew
  • Sugars and browning products peak in the middle of the extraction
  • Mapping specific sensory defects to their chemical extraction state
  • Plant fibers and bitter alkaloids are the final components to dissolve
  • Sequencing the chronological evolution of flavor in a single brew cycle
  • Extraction yield is fixed once the water leaves the coffee bed
  • Applying temperature adjustments to target specific flavor profiles
  • Localized turbulence can create 'channels' where water flows faster, leading to uneven extraction
