,Q1. In a warming climate scenario, a premium Pinot Noir producer in Burgundy's
Côte de Nuits is considering adaptation strategies. Which combination of viticultural
adjustments would most effectively preserve aromatic freshness and acidity while
maintaining phenolic maturity?
A. Switch to late-ripening clones and increase leaf removal on the morning side
B. Implement deficit irrigation and delay harvest to increase sugar accumulation
C. Adopt higher trellising with increased canopy shading and earlier harvest
D. Move to lower-elevation vineyards with deeper soils and south-facing aspects
Correct Answer: C. Adopt higher trellising with increased canopy shading and earlier
harvest
Rationale: Higher trellising (e.g., VSP) with increased canopy shading mitigates sunburn
and slows sugar accumulation, while earlier harvest preserves acidity and reduces
alcohol. Deficit irrigation and later harvest exacerbate the effects of warming. Lower
elevation and south-facing aspects increase heat, not mitigate it.
Why Wrong:
A - Late-ripening clones may still struggle with heat, and morning-side leaf removal
increases sun exposure, worsening heat stress.
B - Deficit irrigation and delayed harvest concentrate sugars and lower acidity,
worsening the impact of warm climates.
D - Lower elevation and south-facing aspects are warmer, exacerbating the problem.

Ch. 2 (Viticulture).
Q2. A winemaker is fermenting a high-sugar must (potential alcohol 15.5%) with a
yeast strain known for high nitrogen demand. They observe a stuck fermentation at
8% alcohol. Which combination of factors is the MOST likely primary cause, and
what corrective action is most appropriate?
A. Excessive initial SO2; aerate vigorously to reoxygenate the yeast
B. Nutrient depletion and ethanol toxicity; add diammonium phosphate (DAP) and
yeast hulls
C. Low fermentation temperature; increase temperature to 35°C to re-activate yeast
D. High initial pH; add tartaric acid to lower pH and stimulate yeast
Correct Answer: B. Nutrient depletion and ethanol toxicity; add diammonium
phosphate (DAP) and yeast hulls
Rationale: High-sugar musts often lead to nitrogen depletion (yeast assimilable nitrogen,
YAN) and ethanol toxicity, causing stuck fermentation. Adding DAP provides nitrogen,
and yeast hulls (inactive yeast) supply sterols and fatty acids to support membrane
integrity. Aeration is not primary, and high temperature (35°C) can increase ethanol
toxicity. pH adjustment is not the direct cause.
Page 3
, Why Wrong:
A - Excessive SO2 can inhibit yeast, but aeration is not a standard corrective action; it
also risks oxidation.
C - Increasing temperature to 35°C may worsen ethanol stress and is not the primary
solution.
D - High pH is not a common cause of stuck fermentation; tartaric acid addition is not
the primary remedy.
Reference: Society of Wine Educators. (2024). CSW Study Guide, Ch. 3 (Winemaking).
Q3. A wine labeled 'Napa Valley' must meet which legal requirement regarding grape
sourcing, according to US regulations?
A. At least 85% of the grapes must be grown in Napa Valley
B. 100% of the grapes must be grown in Napa Valley
C. At least 75% of the grapes must be grown in Napa Valley, and the wine must be
finished there
D. The wine must be produced entirely within Napa County, but grapes can be sourced
from adjacent counties
Correct Answer: A. At least 85% of the grapes must be grown in Napa Valley
Rationale: Under US law (27 CFR 4.25), an appellation of origin like 'Napa Valley'
requires that at least 85% of the wine's volume be derived from grapes grown within that
appellation. The wine must also be finished within the state, but the 85% rule is the key
grape-sourcing requirement.
Why Wrong:
B - 100% is required only for 'estate bottled' claims, not for appellation designations.
C - 75% is the threshold for varietal labeling, not appellation.
D - Grapes must come primarily from the named appellation, not adjacent counties.
Reference: Society of Wine Educators. (2024). CSW Study Guide, Ch. 9 (Wine Law and
Labeling).
Q4. A blind tasting presents a white wine with pronounced aromas of petrol, lanolin,
and quince, high alcohol, low acidity, and a viscous texture. Which grape variety and
region is MOST consistent with this profile?
A. Chenin Blanc from Vouvray
B. Riesling from the Mosel
C. Gewürztraminer from Alsace
D. Viognier from Condrieu
Correct Answer: B. Riesling from the Mosel
Rationale: Petrol (kerosene) aroma is a classic marker of aged Riesling, particularly from
warm vintages or regions with high ripeness. The Mosel typically produces lower-alcohol,
