Q

The features specific to sake rice make what three things possible?

A
  1. The separation of a large proportion of desirable starch away from undesirable impurities.
  2. Help the water penetrate deep into the grain during washing, soaking, and steaming.
  3. Water penetrability also helps the rice ‘melt’ easily, making its starch available for conversion to sugar and then fermentation into alcohol.

Q

How many stages of drying rice are there?

A

Three

20
Q

The bran and outer layers of unpolished rice contain large amounts of what?

A

Fats, proteins, vitamins, lipids, and minerals.

21
Q

What happens if there is an overabundance of fats, proteins, vitamins, lipids, and minerals?

A

It can accelerate the fermentation and kōji propagation and could cause problems with the fermentation. It also makes it more difficult to achieve the precise and elegant flavours that arise from a long, slow fermentation.

22
Q

Why must rice polishing be done slowly and gently?

A

The grains can become heated, dry out, or crack from the heat and friction.

23
Q

To polish 600kg of brown rice to semibuai of 70% takes how long?

And what level is this?

A

10 hours

Junmai

24
Q

To polish 600kg of brown rice to reach 50% semibuai takes how long?

And what level is this?

A

45 hours

Daiginjo

25
Q

A course emery is used for how much of the rice polishing?

A

85% semibuai

26
Q

What happens immediatly after milling?

A

Polished rice is rested to cool down and restore moisture level in order to avoid the risk of cracks caused by an immediate temperature change in water.

27
Q

How long is polished rice rested?

A

Three to four weeks depending on climate.

Q

How can weather conditions impact rice growth?

A

Low temperatures and insufficient sunlight during panicle and grain formation can result in smaller grains that are more soluable and result in heavier-tasting sake.

Higher-than-normal temperatures result in grains that are less soluable, boosting the amount of sakekasu and resulting in weaker sake.
