Dialing In Your Daily Brew
Like Duolingo, but for Dialing In Your Daily Brew. 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 Mastering the Extraction Loop and The Science of the Bean. It assumes you already know the basics.

Key ideas in Dialing In Your Daily Brew
- The 1:16 ratio balances coffee solids with water for ideal mouthfeel
- Under-extraction leaves the brew tasting sour or salty without sweetness
- Using 20g of coffee for 320g of water maintains this structural balance
- Acids and salts dissolve from coffee grounds faster than sugars and oils
- Ratios significantly higher than 1:16 often result in weak, watery brews
- Short brew times or cold water prevent the full extraction of balancing flavors
- Applying the 1:16 ratio to achieve balanced body and strength
- Identifying the sensory profile of under-extracted coffee
- Over-extraction occurs when water begins dissolving the bean's woody cellulose
- A dry, 'sandpaper' sensation on the tongue is a hallmark of over-extracted coffee
- Bitterness increases as the water breaks down heavy organic compounds late in the brew
- Longer contact times require larger particles to slow down flavor release
- Fine grounds have more surface area and extract almost instantly
- Coarse grounds protect against over-extraction during long immersion steeps
- Adjusting grind size based on contact time to prevent extraction errors
- Recognizing the physical cause of over-extraction bitterness
