Growing and Processing Methods
Knowledge check
Q1. Which coffee processing method involves removing the cherry's fruit pulp immediately after harvest, then fermenting and washing the beans before drying?
- A. Natural (dry) processing
- B. Washed (wet) processing ✓
- C. Honey processing
- D. Anaerobic processing
Why: Washed processing removes the fruit pulp mechanically soon after harvest, followed by fermentation to break down the remaining mucilage, washing, and drying. It typically produces cleaner, brighter flavors that highlight the bean's origin characteristics.
Q2. What is the main characteristic of natural (dry) processed coffee?
- A. The whole coffee cherry is dried intact before the beans are extracted ✓
- B. The beans are soaked in water for several days
- C. The fruit pulp is removed with a machine before drying
- D. The beans are roasted inside the cherry
Why: In natural processing, coffee cherries are laid out to dry in the sun with the fruit still attached. The sugars from the fruit penetrate the bean, often producing fruity, sweet, and full-bodied flavors.
Q3. Which country is most famous for growing Arabica coffee in its original genetic homeland, Ethiopia?
- A. Brazil
- B. Vietnam
- C. Ethiopia ✓
- D. Colombia
Why: Ethiopia is widely regarded as the birthplace of Arabica coffee, where wild coffee plants still grow in forests. Its diverse heirloom varieties are highly prized by specialty roasters.
Q4. What is the botanical name of the coffee species that accounts for most specialty-grade coffee production?
- A. Coffea canephora
- B. Coffea liberica
- C. Coffea arabica ✓
- D. Coffea excelsa
Why: Coffea arabica produces the majority of specialty coffee because of its nuanced flavor complexity and acidity. Robusta (Coffea canephora) is more widely grown commercially but is generally considered less refined in flavor.
Q5. Why do coffee cherries need to be harvested selectively, often by hand?
- A. Because machines cannot grow coffee plants
- B. Because cherries ripen unevenly on the same branch ✓
- C. Because unripe cherries are required for roasting
- D. Because the plants only produce fruit once per decade
Why: Coffee cherries on the same plant ripen at different times, so pickers must select only fully ripe fruit. Picking unripe or overripe cherries introduces defects that negatively affect the final cup quality.

Module 4: Brewing Techniques
Brewing Techniques
Knowledge check
Q1. Which brewing method involves pouring hot water over ground coffee held in a cone-shaped filter, allowing gravity to pull the water through?
- A. French press
- B. Pour-over ✓
- C. Espresso
- D. Cold brew
Why: Pour-over brewing uses a filter cone (such as a V60 or Chemex) and relies on gravity to draw water through the coffee grounds, giving a clean, bright cup with good control over extraction.
Q2. What is the typical grind size for French press coffee?
- A. Extra fine, like powder
- B. Fine, like table salt
- C. Medium, like sand
- D. Coarse, like sea salt ✓
Why: French press uses a coarse grind because the coffee steeps for several minutes and is separated by a metal mesh filter. Finer grounds would over-extract and pass through the mesh, leaving sediment and bitterness.
Q3. What does 'bloom' refer to in coffee brewing?
- A. The crema that forms on espresso
- B. Adding a small amount of water to fresh grounds so they release CO2 before full brewing ✓
- C. Rinsing the paper filter with hot water
- D. The final stage where the last drips fall from the dripper
Why: Blooming means wetting freshly roasted grounds with a small amount of water and waiting about 30 to 45 seconds. The trapped CO2 escapes, allowing water to contact the grounds evenly for a more uniform extraction.
Q4. What water temperature is generally recommended for brewing specialty coffee?
- A. Around 60 to 70 degrees C
- B. Around 90 to 96 degrees C ✓
- C. Boiling water at 100 degrees C
- D. Around 80 degrees C regardless of method
Why: The Specialty Coffee Association generally recommends water between about 90 and 96 degrees C. Water that is too cool under-extracts, leaving sour flavors, while boiling water can over-extract and produce harshness.
Q5. Which factor most directly controls how quickly coffee extracts during brewing?
- A. The color of the brewing vessel
- B. The grind size ✓
- C. The brand of water filter
- D. The time of day the coffee is brewed
Why: Grind size directly affects surface area. Finer grounds expose more surface to water and extract faster, while coarser grounds extract more slowly. Adjusting grind is the primary way to correct under- or over-extraction.

Q4. Why do cuppers typically break the crust formed on the surface of the cup before tasting?
- A. To cool the coffee more quickly
- B. To release aromatics trapped under the crust and assess the wet aroma ✓
- C. To remove grounds that would alter the flavor
- D. To add oxygen that increases sweetness
Why: Breaking the crust with a spoon releases volatile aromatic compounds that were trapped, allowing the evaluator to assess the wet aroma before slurping the coffee.
Q5. What does the term 'slurping' serve to accomplish during cupping?
- A. It dilutes the coffee to a standard strength
- B. It aerates the coffee and spreads it across the palate for fuller flavor evaluation ✓
- C. It removes bitter oils from the surface
- D. It helps the coffee cool to a safe drinking temperature

- D. Serving every drink with the same default recipe regardless of request
Why: Specialty cafes value hospitality and education, so staff who listen to preferences and offer informed suggestions, such as recommending a fruity washed coffee to someone who likes bright flavors, create the most satisfying experience.
Q4. What does 'dialing in' an espresso shot mean?
- A. Calling the supplier to order fresh beans
- B. Adjusting grind size, dose, and extraction time until the shot tastes balanced ✓
- C. Setting the espresso machine's timer for the morning opening
- D. Measuring the milk temperature for steaming
Why: Dialing in is the iterative process of tweaking variables like grind fineness, dose weight, and extraction time to achieve a well-balanced shot, which changes with each new bag of coffee.
Q5. Why do many specialty cafes display the roast date on their coffee bags?
- A. To show how long the bag has been sitting on the shelf for sale
- B. Because coffee is best used within a few weeks of roasting, when flavors are at their peak ✓
- C. Because roast dates are legally required for all food products in every country
- D. To indicate the year the farm was originally established
