WINE PRODUCTION & VITICULTURE (Questions 1–25)
1. Optimal grape ripeness for still red wine is judged primarily by:
a) Sugar only
b) Balance of sugar, acid, phenolic maturity (tannins, color), and flavor development
c) Color alone
d) Berry size
, b) Balance of sugar, acid, phenolic maturity (tannins, color), and flavor
development
Rationale: WSET emphasizes holistic ripeness; overripe loses acidity and freshness.
2. Which vineyard practice reduces disease pressure in humid climates?
a) Dense planting
b) Leaf pluck around grape zone for airflow and sunlight
c) Heavy irrigation
d) Late pruning
b) Leaf pluck around grape zone for airflow and sunlight
Rationale: Improves spray penetration, reduces Botrytis and downy mildew.
3. Carbonic maceration is associated with:
a) Barolo
b) Beaujolais Nouveau (whole berry intracellular fermentation)
c) Champagne
d) Chablis
b) Beaujolais Nouveau (whole berry intracellular fermentation)
Rationale: Produces fruity, low-tannin wines; CO₂ anaerobic environment.
4. Malolactic fermentation converts:
a) Sugar to alcohol
b) Malic acid to lactic acid, reducing acidity and adding complexity (diacetyl)
c) Tartaric to citric
d) Alcohol to acetic acid
b) Malic acid to lactic acid, reducing acidity and adding complexity
(diacetyl)
Rationale: Standard for most reds and some whites (Chardonnay); bacterial process.
5. Which additive is used to stabilize tartrates in cold climates?
a) Sulfur dioxide
b) Metatartaric acid or chilling/cold stabilization
c) Sugar
d) Water
b) Metatartaric acid or chilling/cold stabilization
Rationale: Prevents crystal precipitation in bottle; contact process or inhibitor.
6. Oak barrel aging contributes:
a) Only color
b) Tannins, vanilla (vanillin), toast, spice, micro-oxygenation
c) Acidity
d) Alcohol
b) Tannins, vanilla (vanillin), toast, spice, micro-oxygenation
Rationale: Extractives depend on oak origin, toast level, age of barrel.
7. Which closure allows minimal oxygen ingress?
a) Natural cork
b) Screw cap with Saran-Tin liner (low OTR)
c) Synthetic cork
d) Glass stopper
b) Screw cap with Saran-Tin liner (low OTR)
Rationale: Excellent for aromatic whites; consistent seal; may require bottle shock
mitigation.
, 8. Traditional method sparkling wine second fermentation occurs:
a) In tank
b) In bottle (prise de mousse)
c) In barrel
d) In press
b) In bottle (prise de mousse)
Rationale: Champagne method; yeast autolysis adds brioche, creaminess.
9. Racking (soutirage) is:
a) Filtering
b) Transferring wine off lees to clarify and aerate gently
c) Pasteurization
d) Fortification
b) Transferring wine off lees to clarify and aerate gently
Rationale: Done periodically; removes sediment, introduces controlled oxygen.
10. Which process removes alcohol from wine?
a) Reverse osmosis or spinning cone (vacuum distillation) under license
b) Heating to 100 °C
c) Freezing
d) Adding water
a) Reverse osmosis or spinning cone (vacuum distillation) under license
Rationale: Permitted in EU/CA for dealcoholized wines; preserves aromatics.
11. Botrytis cinerea (noble rot) requires:
a) Continuous humidity
b) Alternating humidity and dryness for infection and concentration
c) High temperature
d) Low sugar
b) Alternating humidity and dryness for infection and concentration
Rationale: Found in Sauternes, Tokaji; desiccates berries, concentrating sugar and
flavor.
12. Carbon footprint in vineyard is reduced by:
a) Heavy machinery use
b) Organic farming, lighter bottles, renewable energy, reduced copper (sulfur)
c) Irrigation
d) Plastic mulch
b) Organic farming, lighter bottles, renewable energy, reduced copper
(sulfur)
Rationale: 2025 WSET emphasizes sustainability; lightweight glass saves transport
emissions.
13. Which training system suits high-vigor sites?
a) Vertical shoot positioning (VSP)
b) Geneva Double Curtain (divides canopy, increases light interception)
c) Cordon
d) Guyot
b) Geneva Double Curtain (divides canopy, increases light interception)
Rationale: Used in NY; reduces disease, improves ripeness in cool climates.
14. Water stress timing is critical:
a) Only at harvest
b) Post-veraison to concentrate flavors without compromising vine health
