Answer key with explanations
The correct answers, each one explained. Open any question to check it.
1 What is the primary process that distinguishes black tea from green tea?
Correct answer: A) Fermentation
Black tea undergoes a full fermentation process, which oxidizes the leaves and changes their color and flavor, while green tea is minimally processed.
2 Which type of tea is typically not fermented?
Correct answer: C) Green tea
Green tea is not fermented; it is quickly steamed or pan-fired to prevent oxidation, preserving its green color and fresh flavor.
3 What is the term for the chemical process that occurs during tea fermentation?
Correct answer: A) Oxidation
Oxidation is the chemical process that occurs during fermentation, affecting the flavor and aroma of the tea.
4 Which tea undergoes partial fermentation?
Correct answer: C) Oolong tea
Oolong tea is partially fermented, resulting in a flavor profile that lies between green and black tea.
5 What is the first step in the tea fermentation process?
Correct answer: A) Withering
Withering is the initial step where freshly picked tea leaves lose moisture, preparing them for the fermentation process.
6 Which component of tea leaves is primarily responsible for the flavor changes during fermentation?
Correct answer: B) Polyphenols
Polyphenols are compounds in tea leaves that change chemically during fermentation, impacting the flavor and aroma.
7 How does fermentation affect the caffeine content in tea?
Correct answer: C) No effect
Fermentation does not significantly alter the caffeine content of tea; it remains relatively constant across different types.
8 Which type of tea is known for its unique post-fermentation aging process?
Correct answer: C) Pu-erh tea
Pu-erh tea undergoes a unique post-fermentation aging process that enhances its flavor over time.
9 What is the effect of temperature on the fermentation process of tea?
Correct answer: A) Higher temperatures speed up fermentation
Higher temperatures can accelerate the fermentation process by promoting the enzymatic reactions that occur in the leaves.
10 What is the final step in the tea fermentation process?
Correct answer: B) Drying
Drying is the final step that halts fermentation and preserves the desired flavor and aroma of the tea.
