QUIZ: Distillation - Obscured Alcohol Products

What is the main reason distillation is required before measuring obscured alcohol products? *

To reduce alcohol content for safety

To evaporate sugars for flavor enhancement

To remove all components except alcohol and water for accurate % vol/vol measurement

To change the alcohol type from ethanol to methanol

According to the TTB-recommended method, what is the starting sample volume before distillation? *

50 ml

75 ml

100 ml

200 ml

What does the condenser do in the distillation setup? *

Adds heat to the alcohol to increase purity

Filters out solids and flavorings

Cools vaporized alcohol and water back into liquid form

Measures the alcohol concentration

When should you stop the distillation process? *

When the distillate reaches the top of the neck

When the distillate reaches the etched mark on the flask

Just after the distillate passes the neck and before it reaches the etched mark

As soon as the flask begins to boil

After collecting the distillate and cooling it in a 20°C water bath, what is the final step before measurement? *

Add ethanol to increase concentration

Add sugar back into the sample

Adjust the volume back to 100 ml using distilled water

Freeze the sample
