Comparing Coffee Brewing Methods
Evaluate how geometry, pressure, filter media, and fluid dynamics alter flavor clarity and tactile mouthfeel. Compare percolation, immersion, vapor, and hydraulic methods to control extraction with precision.
Like Duolingo, but for Comparing Coffee Brewing Methods. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
23 levels across 3 sections, about 46 minutes end to end, roughly 9 days at five minutes a day. It moves through Filtration Architecture and Tactile Dynamics; Pressure, Vapor, and Thermal Profiles; and Suspensions, Gravity Beds, and Ambient Dynamics.

Key ideas in Comparing Coffee Brewing Methods
- Dense bonded paper forms a tighter weave that strips out nearly all diterpenes (cafestol/kahweol) alongside micro-fines
- Removing insoluble oils and micro-fines drops perceived viscosity to an ultra-light, tea-like state
- Eliminating the lipid film allows delicate, volatile aromatic compounds to be perceived distinctly without palate coating
- Metal mesh allows insoluble micro-particulate and emulsified lipids to enter the brew freely
- Colloidal suspensions mute volatile aromatics like jasmine and bergamot through sensory masking
- Cloth acts as a selective barrier, blocking insoluble grit while permitting lipid droplets to slip through
- Cellulose fibers trap emulsified lipid droplets that would otherwise coat the tongue
- Mouthfeel perception shifts from velvety/buttery to clean and tea-like in direct proportion to lipid removal
- Cloth allows emulsified lipids through while completely trapping insoluble micro-fines
- The presence of oils without silt yields a heavy, syrupy, or glide-like mouthfeel entirely free of chalkiness
- Cloth brews possess greater body than paper brews while displaying cleaner finishing cups than metal brews
- Turbidity (suspended micro-fines and oil droplets) forms a physical film on lingual receptors
- This colloidal barrier dampens the immediate neural perception of malic, citric, and phosphoric acids
- Clean, low-turbidity cups deliver free organic acids directly to the palate without tactile interference
- Bed depth increases toward the cone's bottom apex, creating a path of least resistance through the deepest central column of coffee
- Water column height and hydraulic head pressure drive the fastest fluid velocities straight down the central axis rather than through the sloping perimeter walls
