Around 700 A.D. in Iraq
What is the approximate "Angel's Share" for a spirit aging in a tropical climate?
As much as 15% evaporation
What is the true judge of a spirit's quality?
Balance
List the main methods of softening spirits
Barrel aging Honey Cocktails Filtration
Wash
The alcohol-bearing liquid being distilled
Alcohol boiling point
173 degrees, Fahrenheit
When was the first column (continuous) still created?
1818, three men are credited with collectively creating the column still distillation method
Distillation
A purification process whereby intense heat is used to separate alcohol from water, creating alcohol vapor, which is then cooled to turn the vapors back into higher-alcohol liquid through condensation.
Other names for Column Still
Continuous Still Patent Still Coffey Still (after Aeneas Coffey)
How much flavor can a barrel impart on a spirit?
Depends on the type of barrel it is and how long the spirit spends in the barrel. However, Scottish distillers claim up to 60%.
Column Still Distillation
Efficient, high-volume distillation method that produces a lighter almost 100% pure spirit
Congeners
Flavors found in the "tails" that are sometimes good or even delicious. Distillers will sometimes keep some of these in the cut to add character and depth of flavor.
Elephant's Head
Oldest believed style of pot still uncovered in what is now Pakistan. Dated between 500 and 300 B.C.
The Cut
Selection of spirit to keep between the "heads" and "tails" - also known as the heart. (Single most important factor in determining a spirit's quality)
Pot Still Distillation
Single batch distillation method that produces a spirit with a lot of character
What are the three main acids found in oak that affect wine and spirits?
Tannin: a preservative Lignin: adds body and texture Vanillin: adds caramel, toffee, vanilla, etc.
