27
Q

28
Q

What is kokutō shōchū?

A

Brown sugar shōchū.

29
Q

What is kōji?

A

The starchy material on whcih filamentous fungi have grown releasing the enzymes required for modification adn starch conversion.

30
Q

What is parallel fermentation?

A

A fermentation in which starch is converted to fermentable sugar at the same time as the sugar is fermented into alcohol by the yeast.

31
Q

What is semi-solid-state fermentation?

A

A fermentation that has a high level of starchy solids in it during fermentation. The starch is released from the solid plant material and converted to fermentable sugar during fermentation

32
Q

What are the most commonly used vessel for maturing shōchū?

A

Earthenware pots. These pots also help to remove sulfur compounds from the spirit.

33
Q

What is soju?

A

A Korean spirit that can be made from a variety of mostly starch-based materials.

34
Q

What are the two legally defined subcategories of soju?

A

Diluted-soju and distilled-soju.

35
Q

What is diluted-soju?

A

These products are neutral spirit which is further rectified, diluted, filtered and flavoured.

36
Q

What filtration technique can be used after dilution in the production of diluted-soju?

A

Activated charcoal filtration.

37
Q

What four factors affect the style of diluted-soju?

A
  1. The amount of purification and filtering, and the technical skill with which these are done.
  2. The water used for dilution (highly purified generally).
  3. The amount of dilution (level of alcohol below 20% abv nowadays).
  4. The level and and kinds of additional flavourings used.
38
Q

What is distilled-soju?

A

These spirits are distilled in a batch process. The raw materials are typically grains or sweet potato mixed with microbe-rich blocks of coarsely ground grains to provide conversion enzymes.

39
Q

What is nuruk?

A

A solid block made from coarsely ground steamed grains that is used as a source of conversion enzymes and yeast. Nuruk is used in the production of distilled-soju.

40
Q

What is the distillation strength of distilled-soju?

A

About 45% abv.

41
Q

What maturation vessels are used in the production of distilled-soju?

A

Traditional ceramic vessels, inert steel vessels or oak barrels.

42
Q

What approach to distillation is typically used in the production of distilled-soju?
