Key ideas in The Architecture of Coffee Drinks
- Crema is an emulsion of CO2 gas and coffee oils forced out by pressure
- High strength (TDS) creates a thick mouthfeel even if the coffee is under-extracted
- Tiger skin mottling indicates high CO2 levels found in very fresh roasts
- Low extraction yield results in sour, salty flavors because sugars haven't dissolved yet
- Stale beans produce thin, pale crema that dissipates quickly
- Yield and strength are independent variables in a single shot
- Distinguishing between concentration and extraction
- Using crema appearance to judge beans
- Water follows the path of least resistance through cracks in the coffee puck
- 9 bars is the industry standard pressure for forcing oils into a stable emulsion
- Distinguishing between the concentration of coffee solids and the total amount extracted from the grounds
- Channeling causes localized over-extraction, leading to harsh bitterness
- Pressure emulsification creates the heavy body unique to espresso vs drip coffee
- Using crema appearance to judge bean freshness and gas content
- Uneven tamping or 'clumpy' grounds create the structural weak points where channels form
- Lower pressure fails to aerate the lipids and gases into a creamy texture

Here's what playing it feels like
A real question from this course. Take your best guess.
If your espresso feels very thick and heavy in your mouth, what does that tell you about its strength (TDS)?
