Section 1: Viticulture
Question 1
The annual growth cycle of the grapevine begins in the spring with the breaking of dormancy, marked by
the appearance of small, green shoots emerging from the buds. What is this stage called?
A) Veraison
, Page 2 of 140
B) Budbreak
C) Flowering
D) Harvest
Answer: B
Rationale: Budbreak is the first stage of the annual growth cycle when the vine emerges from dormancy
and new shoots begin to grow.
Question 2
Which of the following is the primary function of a trellis system in a vineyard?
A) To increase grape sugar concentration
B) To expose leaves and grape clusters to sunlight and air
C) To prevent frost damage during the spring
D) To reduce the need for irrigation
Answer: B
Rationale: Trellising supports the vine canopy, optimizing sun exposure and air circulation around the
grape clusters, which is essential for ripening and disease prevention.

Question 3
The process by which grape skins and seeds are separated from the juice immediately after crushing,
typically used for white wine production, is called:
A) Maceration
B) Pressing
C) Pumping over
D) Racking
Answer: B
Rationale: For white wines, pressing occurs immediately after crushing to separate the juice from the
skins and seeds, minimizing color and tannin extraction.
Question 4
Which grape variety is the most widely planted in the world?
A) Cabernet Sauvignon
B) Merlot
C) Airén
D) Chardonnay
, Page 4 of 140
Answer: C
Rationale: Airén, a white grape variety from Spain, historically held the title of the most planted grape in
the world due to its extensive cultivation in the La Mancha region.
Question 5
During fermentation, yeast converts sugar into alcohol and carbon dioxide. What is the chemical
equation for this process?
A) C₆H₁₂O₆ + O₂ → 2 C₂H₅OH + 2 CO₂
B) C₆H₁₂O₆ → 2 C₂H₅OH + 2 CO₂
C) C₂H₅OH + O₂ → CH₃COOH + H₂O
D) C₆H₁₂O₆ → 2 C₃H₆O₃
Answer: B
Rationale: The basic fermentation equation is sugar (glucose/fructose) converted to ethanol and carbon
dioxide in the absence of oxygen.

Question 6
Which of the following is NOT a subregion of the Bordeaux wine region?
