Distillation Process Flashcards

What is the primary purpose of distillation in bourbon production?

Answer: To separate and concentrate alcohol

Distillation separates alcohol from the fermented mash by heating it, allowing for the concentration and purification of ethanol.

Which type of still is most commonly used in bourbon production?

Answer: Column still

A column still, also known as a continuous still, is most commonly used in bourbon production for efficiency and consistency.

At what proof is bourbon typically distilled?

Answer: No higher than 160 proof

By law, bourbon must be distilled at no higher than 160 proof (80% alcohol by volume) to retain flavor components.

What is the purpose of the doubler in bourbon distillation?

Answer: To refine and purify the distillate

The doubler is a secondary distillation step that refines the spirit, removing impurities and enhancing smoothness.

Why is the 'heart' cut important in bourbon distillation?

Answer: It contains the best portion of the distillate for aging

The heart cut contains the desirable ethanol and flavor compounds, while the heads and tails contain unwanted impurities.

What happens to the heads and tails in the distillation process?

Answer: They are discarded or redistilled

The heads and tails contain undesirable compounds and are often redistilled or discarded to ensure quality bourbon.
