What is a backset?
In bourbon production, some of the residue from the first distillation run. It is placed back in the fermenter for use in the next fermentation batch.
What is sour mashing?
The use of backset, which is highly acidic, to counteract local water with high alkaline content used in bourbon production. It also assists with creating a consistent product.
How is bourbon generally distilled?
It is usually double-distilled (some may be triple-distilled) in either pot or column stills.
Where does the first distillation of bourbon generally occur?
In a pot or single column still composed of copper or stainless steel, known as a beer still.
In bourbon production, where does the second distillation take place?
In a doubler or thumper.
What is a doubler?
An addition to a pot still where the second distillation of bourbon occurs. It continuously receives the low wines, drives them to a chamber that contains heated liquids, causing an interaction that concentrates the alcohol and refines unwanted congeners.
What is a thumper?
A type of doubler that receives the vapors from the first distillation run before they have been cooled and condensed.
How does a thumper work?
As vapors from the first distillation enter the thumper, they are driven into water kept above the boiling point of ethanol but below that of water. The ethanol vapor continues on through the water for condensation as a new-make spirit. Tails are captured by the water and drained off.
How does bourbon get its color?
Through time spent in wood only - caramel coloring is prohibited (except for bourbons labeled as blends)
