Question 1: What is the role of pre-infusion in espresso brewing, and why is it essential for proper extraction?

Which action should you take?

Choose only one option

Pre-infusion is only for pour-over coffee, not espresso

Pre-infusion increases the pressure and speed of extraction

Pre-infusion wets the coffee grounds, allowing them to expand and ensuring even extraction

Pre-infusion makes the coffee weaker

Question 2: How do you determine ideal espresso shot consistency using a coffee refractometer?

Which action should you take?

Choose only one option

By checking the crema thickness

By measuring the TDS (total dissolved solids) to gauge consistency in flavor strength

By measuring the weight of the shot

By adjusting the brewing time based on shot temperature

Question 3: How does the type of grinder used affect espresso quality?

Which action should you take?

Choose only one option

Burr grinders are only necessary for drip coffee, not espresso

Blade grinders ensure a smoother extraction and are preferred for espresso preparation

Blade grinders are ideal for espresso due to their ability to create finer, more intense grinds

Burr grinders produce a consistent grind size, improving extraction and flavor consistency

Question 4: What does the term "crema" refer to in espresso, and what factors influence its quality?

Which action should you take?

Choose only one option

Crema refers to the milk foam formed after steaming, which affects the texture of the espresso

Crema is the consistency of milk foam, unrelated to espresso quality

Crema forms from over-extracted espresso, which enhances flavor intensity

Crema is the golden, foamy layer that forms on top of espresso, influenced by bean freshness and extraction time

Question 5: What is the ideal pour speed for creating complex designs such as a tulip or heart in latte art?

Which action should you take?

Choose only one option

Fast and steady to fill the cup quickly

The pour speed should be slow and controlled to create layers of foam and ensure precision in the design

Quick but with little control to get a light design

Irrelevant, as pour speed doesn't affect the design

Question 6: What is the significance of freshness when serving latte art, and how does it influence the final presentation?

Which action should you take?

Choose only one option

Freshness does not affect the quality of latte art

Fresh milk makes the design less stable and more difficult to pour

Any milk, whether fresh or not, can create the same quality of latte art

Fresh milk creates the best microfoam for latte art, ensuring clean, sharp designs with lasting texture
