COURSE EXAM Practice Study Guide — 200 Questions
═══════════════════════════════════════════
1. What is the standard espresso extraction time recommended by the SCA?
A. 10–15 seconds
B. 20–25 seconds
C. 25–35 seconds
D. 40–50 seconds
E. 55–60 seconds
Correct Answer: C. 25–35 seconds RATIONALE: The SCA defines a standard
espresso shot as extracting within 25–35 seconds. This window allows for optimal
dissolution of soluble compounds, balancing sweetness, acidity, and bitterness in
the cup.
,2. What is the SCA recommended dose for a standard double espresso
(doppio)?
A. 7–9 grams
B. 10–12 grams
C. 14–18 grams
D. 20–22 grams
E. 25–30 grams
Correct Answer: C. 14–18 grams RATIONALE: The SCA standard for a double
espresso (doppio) is 14–18 grams of ground coffee. This dose, combined with
correct grind size and extraction time, produces a well-balanced shot.
3. What brew ratio is most commonly used as the SCA standard for espresso?
A. 1:1
B. 1:2
C. 1:3
D. 1:4
E. 1:5
Correct Answer: B. 1:2 RATIONALE: A 1:2 brew ratio means for every gram of
ground coffee, you yield 2 grams of liquid espresso. For example, 18g in produces
36g out. This ratio is the SCA benchmark for balanced espresso.
4. Which of the following best describes "channeling" in espresso extraction?
A. Over-extraction due to too fine a grind
B. Water finding paths of least resistance through the puck
C. The crema dissipating too quickly after pulling a shot
,D. Milk overheating during steaming
E. Under-dosing the portafilter basket
Correct Answer: B. Water finding paths of least resistance through the
puck RATIONALE: Channeling occurs when water bypasses part of the coffee puck
and flows through weak spots, resulting in uneven extraction. It is often caused by
poor tamping, uneven distribution, or a damaged puck.
5. What does TDS stand for in the context of coffee brewing?
A. Total Dissolved Substances
B. Total Dissolved Solids
C. Temperature-Dependent Solubility
D. Timed Dispersion System
E. Total Drip Saturation
Correct Answer: B. Total Dissolved Solids RATIONALE: TDS measures the
concentration of dissolved coffee compounds in a brewed cup, expressed as a
percentage. It is a key indicator used alongside extraction yield to evaluate brew
quality.
6. According to SCA brewing standards, what is the optimal brewing water
temperature for espresso?
A. 80–85°C
B. 88–92°C
C. 93–96°C
D. 98–100°C
E. 100–105°C
, Correct Answer: C. 93–96°C RATIONALE: The SCA recommends a brewing
water temperature of 93–96°C for espresso. Water at this range extracts coffee
solubles efficiently without scorching the grounds, which would cause harsh, bitter
flavors.
7. What is the primary purpose of tamping espresso grounds?
A. To heat the coffee before extraction
B. To create a uniform, even resistance for water flow
C. To remove excess moisture from the grounds
D. To activate the oils in the coffee
E. To reduce the dose weight
Correct Answer: B. To create a uniform, even resistance for water flow
RATIONALE: Tamping compresses the coffee grounds into a dense, level puck,
ensuring water flows evenly through the entire dose during extraction and
preventing channeling or uneven extraction.
8. What is the recommended tamping pressure in espresso preparation?
A. 5 kg (11 lbs)
B. 10 kg (22 lbs)
C. 20 kg (44 lbs)
D. 30 kg (66 lbs)
E. 50 kg (110 lbs)
Correct Answer: C. 20 kg (44 lbs) RATIONALE: The widely accepted standard
tamping pressure is approximately 20 kg (44 lbs). More important than the exact
pressure is consistency — applying the same level of pressure every time ensures
repeatable extractions.
