CHAPTER 4: WHISKIES Flashcards
Whisky/Whiskey
Where is whiskey produced?
Everywhere
Whisky/Whiskey
What is the four (4) point standard of Whisky? (recognized in international trade agreements)
- Spirit obtained from fermented mash of grain
- Distilled at less than 95% ABV
- Stored in oak barrels
- Bottled at no less than 40% ABV
Whisky/Whiskey
What is the only spirit that must be made exclusively from grain?
Whisky
Whisky/Whiskey
What generally determines the type and combination of grains used in whisky production?
The country or region in which the whiskey is produced.
Whisky/Whiskey
Who was first believed to produce Whisky?
It is believed to be Irish Celts
Whisky/Whiskey
What was the first evidence of whiskey production?
The Exchequer Rolls of Scotland, in the last decade of the 15th Century shows an order from the king for a monk to make malt into aqua vitae.
Whisky/Whiskey
What does uisgebeathe or uisgebaugh mean?
Water of Life
Whisky/Whiskey
Which countries use the spelling “Whisky”? (no E)
Scotland and Canada. US varies.
Whisky/Whiskey
What is the five (5) step production procedure for Whisky?
- Mash/Wort Preparation
- Fermentation
- Distillation
- Maturation
- Blending and Bottling
Whisky/Whiskey
What are the four (4) primary grains used in making whisky?
- Barley
- Corn
- Rye
- Wheat
Whisky/Whiskey
Which of the four primary grains is malted or sprouted? Why?
Barley, since it is the most prolific source of enzymes.
Whisky/Whiskey
Does a grain recipe require a substantial amount of barley to convert the other starches into fermentable sugars?
No, a small amount is required.
Whisky/Whiskey
What two (2) enzymes are released with a grain sprouts?
- Alpha Amylase
2. Beta Amylase
Whisky/Whiskey
What does Diatase do?
The enzyme breaks down the carbohydrates or starches into maltose.
Whisky/Whiskey
What is the role of Maltose?
It is the bi-molecular sugar produced from the diatase and carbohydrate or starch reaction. This sugar further breaks down into a simple sugar with can then be fermented by yeast.
Whisky/Whiskey
During which phase do the enzymes become active.,Malting or Mashing?
Mashing
Whisky/Whiskey
When barley is germinated (malted) what is it called?
Green malt
Whisky/Whiskey
What is done with Green Malt?
It is kilned to stop germination and conclude the Malting phase.
Whisky/Whiskey
How does kilning play a role in flavor profiles?
The time and temperature of the heating process caramelizes the sugars in the malted grain
Whisky/Whiskey
What is the next step for kilned or roasted malt?
It is screened and ground into grist.
Whisky/Whiskey
What is done with the Grist?
It is mixed with hot water and heated to 135-170 degrees F in a Mash Cooker (US term) or Mash Tun (EU term)
Whisky/Whiskey
What occurs in the Mash Cooker or Mash Tun?
The water dissolves the sugars and liquefies most of the remaining starches. Diastase completes the conversion process. Starch is converted to sugar.
Whisky/Whiskey
Why are the Diatase enzymes able to become active?
The heat
Whisky/Whiskey
What does Scotland and Ireland call “Mash” or “Wort”?
The sugary liquid that is “washed” from the malt. It is drained off.
