Coffee Styles and Terminology
Move beyond the basics to decipher coffee menus, bag labels, and flavor wheels. Learn how bean genetics, regional processing, and extraction ratios shape the profile of every cup you drink.
Like Duolingo, but for Coffee Styles and Terminology. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
18 levels across 3 sections, about 36 minutes end to end, roughly 7 days at five minutes a day. It moves through The Espresso and Brew Matrix; Origins, Cultivars, and Processing; and Sensory Analysis and Extraction Science. It assumes you already know the basics.

Key ideas in Coffee Styles and Terminology
- A 1:2 dry coffee to liquid yield ratio defines standard normale espresso
- Ristretto cuts the yield short to accentuate sweetness and syrupy body
- Lungo pulls more water through the puck to yield higher, bitter extraction
- Cortado uses an equal 1:1 ratio of espresso to warm steamed milk
- Flat white balances a double shot with roughly 4 oz of silky microfoam
- Cappuccino blends espresso with equal parts steamed milk and aerated foam
- Latte incorporates the greatest volume of steamed milk to dilute espresso
- Macchiato translates to 'stained' or 'spotted' in Italian
- A traditional macchiato is a single or double espresso dotted with a dollop of milk foam
- Commercial caramel macchiatos are large vanilla-flavored milk drinks with espresso poured over top
- Which extraction ratio and flavor profile corresponds to each core espresso pull style
- Pulling espresso directly onto hot water yields a Long Black with an intact crema
- Adding hot water onto espresso breaks the emulsified crema layer into an Americano
- An intact crema layer retains aromatic volatile compounds at the cup's surface
- Crema consists of carbon dioxide bubbles emulsified with coffee oils and fines
- Isolated crema tastes intensely bitter, astringent, and unpleasantly harsh
