Dialing In Your Daily Brew
Move beyond following recipes to understanding the variables of extraction. Learn to diagnose flavor imbalances and manipulate grind, temperature, and water to craft your perfect cup.
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.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Mastering Extraction and The Source of Flavor. It assumes you already know the basics.

Key ideas in Dialing In Your Daily Brew
- Acids dissolve first, making under-extracted coffee taste sour
- Over-extraction pulls out heavy polyphenols that cause dryness
- Saltiness is a chemical byproduct of incomplete extraction
- Bitterness increases as water stays in contact with grounds too long
- Under-extracted coffee lacks the sugars that balance acidity
- Astringency is a tactile mouthfeel, not just a flavor
- Identifying under-extraction through sensory cues
- Recognizing the physical sensation of over-extraction
- Sweetness is the result of balancing acidity and bitterness
- Acids and salts extract in the first few seconds
- The window for peak sweetness is very narrow in the brew cycle
- Maximum sweetness occurs just before over-extraction begins
- Understanding the flavor evolution in a Salami Shot
- Finer grounds increase surface area to fix sour under-extraction
- Defining the goal of the 'Sweet Spot'
- Coarser grounds reduce extraction to eliminate bitter notes
