Study Notes
Coffee Beans
- Coffee beans are the seeds of the coffee plant (Coffea arabica or Coffea canephora)
- There are over 100 coffee-producing countries, but 70% of coffee comes from the "Bean Belt" (near the equator)
- Coffee beans can be classified into two main categories:
- Arabica (70% of production): mild and nuanced flavor, higher acidity, grown at high altitudes
- Robusta (30% of production): bolder and harsher flavor, higher caffeine content, easier to grow and more disease-resistant
Espresso
- Espresso is a concentrated coffee beverage made by forcing pressurized hot water through finely ground coffee beans
- Typical espresso serving size: 1-2 oz (30-60 ml)
- Espresso roast is typically darker than other coffee roasts to bring out a bolder flavor
- Key characteristics of espresso:
- Thick, creamy crema (foam) on top
- Rich, intense flavor
- High caffeine content (due to concentration)
Flavor Profiles
- Coffee flavor profiles can be influenced by:
- Region: different regions have distinct flavor profiles (e.g. Ethiopian coffee is known for fruit notes)
- Altitude: higher altitudes can result in brighter, more acidic flavors
- Processing method: e.g. natural, washed, or honey processing can affect flavor
- Roast level: lighter roasts have more acidity, darker roasts have more body
- Common flavor notes in coffee:
- Fruity (e.g. citrus, berries)
- Floral (e.g. rose, jasmine)
- Nutty (e.g. hazelnut, almond)
- Chocolatey
- Earthy (e.g. soil, moss)
- Smoky or spicy

Coffee Bean Classification
- Arabica beans make up 70% of production, offering a mild and nuanced flavor, higher acidity, and are grown at high altitudes.
- Robusta beans make up 30% of production, offering a bolder and harsher flavor, higher caffeine content, and are easier to grow and more disease-resistant.

- A typical espresso serving size is 1-2 oz (30-60 ml).
- Espresso roast is typically darker than other coffee roasts to bring out a bolder flavor.
- Key characteristics of espresso include a thick, creamy crema (foam) on top, rich, intense flavor, and high caffeine content due to concentration.
Flavor Profiles
- Coffee flavor profiles are influenced by region, altitude, processing method, and roast level.
- Regional flavor profiles vary, with Ethiopian coffee known for fruit notes, for example.
- Higher altitudes can result in brighter, more acidic flavors.
- Different processing methods, such as natural, washed, or honey processing, can affect flavor.
- Roast level affects flavor, with lighter roasts having more acidity and darker roasts having more body.
- Common flavor notes in coffee include fruity, floral, nutty, chocolatey, earthy, smoky, and spicy.
