CERTIFIED SPECIALIST OF

SPIRITS PRACTICE EXAM

Question 1: During alcoholic fermentation, what is the principal role of yeast?

Choices:

1) Convert sugars into ethanol and carbon dioxide 2) Convert ethanol into acetic acid 3) Extract tannin from oak 4) Concentrate alcohol by evaporation

Correct Answer: Convert sugars into ethanol and carbon dioxide

Explanation: Yeast metabolizes fermentable sugars, producing ethanol and carbon dioxide as primary products of alcoholic fermentation.Page 1

Question 2: Why is distillation able to increase the alcoholic strength of a fermented liquid?

Choices:

1) Ethanol is denser than water 2) Ethanol is more volatile than water 3) Water chemically binds to the still 4) Yeast continues fermenting during distillation

Correct Answer: Ethanol is more volatile than water

Explanation: Ethanol is more volatile than water, so the vapor formed during heating is richer in ethanol than the original fermented liquid.

Question 3: What is the main function of a condenser in a distillation system?

Choices:

1) To ferment the wash 2) To convert vapor back into liquid 3) To char oak barrels 4) To remove congeners with charcoal

Correct Answer: To convert vapor back into liquid

Explanation: The condenser cools alcoholic vapor leaving the still so that it condenses back into liquid distillate.Page 2

Question 4: Compared with repeated pot distillation, a continuous column still is especially suited to which goal?

Choices:

1) Producing spirit continuously at relatively high strength 2) Creating only heavily peated spirit 3) Aging spirit during distillation 4) Preventing any separation of fractions

Correct Answer: Producing spirit continuously at relatively high strength

Explanation: A column still can operate continuously and e�ciently produce high-strength distillate while separating fractions through multiple plates or stages.

Question 5: In pot distillation, why are the heads and tails commonly separated

from the heart cut?

Choices:

1) They contain no alcohol 2) They contain compounds that may be undesirable in the �nal spirit 3) They are always legally prohibited from redistillation 4) They are the only fractions that contain water Correct Answer: They contain compounds that may be undesirable in the �nal spirit Explanation: Heads and tails contain di�erent volatile and less-volatile compounds; distillers manage these cuts to shape quality, aroma, and �avor.Page 3
