Vocabulary Flashcards
ABV
(Alcohol by Volume)
The amount of alcohol in a spirit (or beer) as a percentage of the total volume. This number is doubled to yield the “Proof” of the spirit
ALDEHYDES
A group of Aromatic compounds found in OAK, with a floral or fruity character.
ANGELS SHARE
The volume of whiskey that is lost during the aging process by evaporation through the barrel
BARLEY (EDIT MORE INFO)
A grain that is relatively easy to malt, with abundant enzymes for converting starches into sugars and a husk that acts as a natural filter; thus well-adapted for brewing and distilling.
BARREL
A container built from curved oak staves, usually charred, that imparts flavor and color to the spirit through chemical changes from contact with the wood and slow evaporation. In American usage the standard size is 53 gallons (200 liters), though craft distillers commonly use smaller barrels.
BEER
The fermented, undistilled liquid that is the first step in making whiskey
BEER STILL
A single column still used for first distillation in making modern bourbon and rye whiskey. Also called a “stripping Column”
BLENDED SCOTCH WHISKEY
A blend of one or more single malt Scotch whiskies with one or more single grain Scotch whiskies. This is the familiar category of whiskey that includes well known brands like Johnnie Walker, Dewar’s and Chivas Regal.
BLENDED WHISKEY
In American usage a blend of straight whiskey and grain neutral spirits; it must be at least 20 percent straight whiskey.
BOURBON
AMERICAN WHISKEY made predominantly of corn (51 PERCENT OR MORE), malt, and either rye or wheat; Distilled to a maximum of 80 percent ABV and aged in a NEW charred oak barrels at an entry proof of no more than 62.5 percent ABVl bottled at a minimum of 40 percent ABV.
WHAT IS WHISKEY?!
A type of distilled alcoholic beverage made from fermented grain mash.
CARAMEL
Cooked and browned sugar; allowed as a coloring agent in European and Canadian whiskey but not allowed in Bourbon or rye whiskey.
CASK
“Cask” is the word used more often in SCOTLAND & IRELAND as the generic term for barrel.
CHAR
The thin layer of burnt wood on the inside of a barrel that has been treated with a flame. Required for Bourbon and other American whiskeys.
COFFEY STILL
A still in the form of two columns that takes in a continuous flow of WASH or BEER, passing it over a series of plates as steam rises through the liquid, heating and “stripping” the alcohol out of the liquid, to be condensed and captured as spirit. Also known as a continuous still.
COLUMN STILL
Column stills allow continuous distillation, meaning they’re capable of drastically higher production than pot stills, which require cleaning after each batch. Column stills also provide a purer, cleaner distillate than pots, though pot stills produce a more flavorsome spirit, richer in congeners
POT STILL
Pot stills form the basis of batch distillation. This means a specified amount of liquid goes into the still and gets distilled into spirit. Then the leftover dregs are dumped, the still gets cleaned out, and the whole process begins anew. This contrasts with continuous distillation which is…well, continuous, but that’s another story for another time.
HYBRID STILL
COOPER
A person who makes, repairs, or resizes barrels.
CORN
A grain native to the Americas; not easy to malt, but an inexpensive, flavorful source of sugars for fermentation and distillation. The major component in bourbon.
CORN WHISKEY
Whiskey made from a large proportion of corn in the mash, and most often aged for only a short period in either uncharred or used oak barrels.
CUTS
The points in a pot still distillation where the stream of spirit is diverted. The first cut is after the foreshots or HEADS have run; the second is when the feints or TAILS begin to run. The cuts are made to get the maximum amount of clean spirit. The HEADS & TAILS are often redistilled to recover all the alcohol.
DISTILLATION
The extraction and concentration of alcohol from a fermented grain liquid by use of controlled heat. Ethyl alcohol - ethanol - evaporates at a lower temperature than water, and the alcohol-rich vapor is condensed and separated from the remaining water and other chemicals.
DOUBLER
A simple pot still used by bourbon distillers to polish the spirit from the beer still.
DRAFF
The leftover grains from the fermentation and distilling process, most often used for cattle feed; there is a move to use it for biogas generation recently. Also called “spent grains’ or “dark grains.”
DRYHOUSE
Where the spent grains from American-style mashing distillation go to be dried and processed for animal feed.
DUNNAGE
A traditional type of warehouse in Scotland, with earthen floors.
ESTER
An aromatic chemical compound derived from ALDEHYDES; can yield fruity, spicy, or smokey aromas.
EXTRACTIVE DISTILLATION
A technique in which water is added to high-proof spirit to float unwanted compounds off the top, leaving a pure spirit. USED by some Canadian Distillers.
