Key ideas in The Art of the Espresso Bar
- Less water creates a thicker, syrupy texture
- Short shots pull out sweetness before bitterness kicks in
- How water volume affects the texture and flavor intensity of the shot
- Ristrettos use the least water for maximum intensity
- Lungos use the most water which can lead to over-extraction
- Mapping the specific shot name to its flavor profile and water usage
- Extra water pulls out harsh, bitter compounds
- Longer shots are more diluted but taste more bitter
- Microfoam is made by folding tiny bubbles into the milk for a silky feel
- Dense foam sits on top of the drink like a separate, heavy layer
- A smaller milk-to-espresso ratio makes the bean's flavor more prominent
- Lattes use more milk, which masks the subtle notes of the espresso
- How the amount of air in milk affects the drink's texture and mouthfeel
- The relationship between milk volume and coffee flavor intensity
- Silky microfoam is fluid enough to blend into the coffee body
- Stiff foam is too light to mix and stays separated at the surface
