CSW Certified Specialist of Wine Exam –Practice Questions
Top 10 Exam Coverage Areas (Most Tested)
1. Wine Composition and Chemistry – Major components: water (80-90%), alcohol (10-15%
typically), acids (0.5-0.75%), sugars, phenolic compounds ; tartaric acid (most prevalent,
strongest in terms of pH), malic acid, lactic acid, succinic acid ; pH range 2.9-4.0; volatile
compounds (ethanol, esters, aldehydes)
2. Grape Varieties and Characteristics – Noble varieties (Cabernet Sauvignon, Pinot Noir,
Chardonnay, Riesling, Sauvignon Blanc, Syrah/Shiraz, Merlot, Nebbiolo, etc.); variety-specific
aromas, acidity, sugar levels; regional associations
3. Viticulture – Growing cycle, canopy management, terroir; effects of climate (cool vs warm) on
grape composition; soil types; harvest considerations (sugar 15-28% at harvest)
4. Vinification and Winemaking Techniques – Alcoholic fermentation (converts sugar to ethanol) ;
red vs white winemaking; malolactic fermentation; oak aging; cold stabilization; carbonic
maceration; rosé production methods
5. Wine Regions of the World – France (Bordeaux, Burgundy, Champagne, Loire, Rhône, Alsace),
Italy (major regions and DOCG/DOC), Spain, Germany, Portugal, New World regions (USA,
Australia, New Zealand, South America, South Africa)
6. Wine Laws and Labeling – Appellation systems (AOC, DOC/DOCG, QmP/QbA, AVA); labeling
requirements; vintage, varietal, and geographic indications; "Contains Sulfites" labeling
requirement (>10 ppm SO2)
7. Wine Service and Etiquette – Service temperature, glassware, opening and decanting, storage,
responsible alcohol service, food and wine pairing principles
8. Sensory Evaluation and Faults – TCA/cork taint, oxidation, volatile acidity, Brettanomyces,
reduction; esters (largest group of odiferous compounds) ; acetaldehyde (oxidation product,
gives sherry its distinct aroma)
9. Sparkling and Fortified Wines – Champagne and méthode traditionelle; other sparkling
methods; Sherry (biological vs oxidative aging), Port, Madeira, Vermouth
10. Health, Safety, and Responsible Service – Health benefits (resveratrol) ; responsible beverage
service; alcohol metabolism; sulfite sensitivities

Question 1
What percentage of wine is typically composed of water according to wine chemistry principles?
• A) 50-60 percent
• B) 60-70 percent
• C) 70-80 percent
• D) 80-90 percent
Answer: D) 80-90 percent
Rationale: Wine is typically 80-90% water, making it the most abundant component of wine .
Question 2
Which acid is the most prevalent acid found in grapes and wines?
• A) Malic acid
• B) Tartaric acid
• C) Citric acid
, Page 3 of 134
• D) Lactic acid
Answer: B) Tartaric acid
Rationale: Tartaric acid is the most prevalent acid found in grapes and wines and is the strongest wine
acid in terms of pH .
Question 3
The primary result of alcoholic fermentation is which of the following?
• A) Lactic acid
• B) Ethyl alcohol (ethanol)
• C) Carbon dioxide only
• D) Glycerol
Answer: B) Ethyl alcohol (ethanol)
Rationale: The primary result of alcoholic fermentation is ethyl alcohol, also referred to as ethanol, which
typically comprises 10-15% of wine volume .

Question 4
Which compound is primarily responsible for the distinct aroma of Sherry wines?
• A) Ethyl acetate
• B) Acetaldehyde
• C) Vanillin
• D) Resveratrol
Answer: B) Acetaldehyde
Rationale: Acetaldehyde is the most common aldehyde in wine, formed by the oxidation of ethanol, and
gives Sherry its distinct aroma .
Question 5
What is the typical pH range of wine?
• A) 1.5 to 2.5
• B) 2.9 to 4.0
• C) 4.5 to 5.5
