The Bottled in Bond Act of 1897 guarantees that any distilled spirit labeled “Bottled-in-Bond” meets the criteria below.
The same distiller, at the same distillery, must make it during the same distilling season. The same distiller must age it for at least four years, and not adulterate it. However, the distiller may add pure water to adjust the proof. Thus the U.S. federal government guarantees the authenticity of the product.
The actual pure alcohol content of a standard drink of a can of beer, glass of dinner wine, or distilled spirit is the same. It’s 0.6 of an ounce.6

III. Bourbon Words & Terms
ABV is proportion of alcohol in a beverage by volume.
ABW is proportion of alcohol in a beverage by weight.
Angel’s share is the whiskey lost by evaporation during aging.
Barrel. A U.S. barrel is holds 31.5 gallons.
Barrel proof. The producer doesn’t dilute the spirit after removing it from the cask or barrel. As a result, it has a higher proof than the traditional spirit.
Bung is the stopper producers use to seal a barrel.

“Where there’s smoke….”
Charred barrels. Coopers use flames to burn or char the interiors of barrels.
Column still. Distillers pump the mash continuously into a column. Steam rises and evaporates the alcohol. Distillers can continue the process repeatedly. Other names are beer still, continuous still, and Coffey still. See pot still.
Congeners are substances in alcohol. They occur in higher quantities in darker spirits. They add flavors. Unfortunately, they can make a hangover worse. So that’s another a good reason not to over-indulge.
Cooker. See mash tub.
DISCUS is the abbreviation for Distilled Spirits Council of the U.S. It’s a trade group of leading distillers.
Distillation
Distillation is the process distillers use to separate alcohol from water. Alcohol evaporates at a lower temperature than water. Therefore, it evaporates first and then distillers condense it back into liquid.
Distiller’s beer. The fermented mash that producers transferred from the fermenter to the still for distillation.
Fermentation is the process during which yeast converts sugar into alcohol and carbon dioxide.
Finish is the lingering aftertaste that results after an alcohol beverage is swallowed.
Fermenter is a container in which distillers add yeast to the mash to begin fermentation.
Jigger is a container for measuring liquids when making mixed drinks.
Juleps
Juleps are traditionally made from bourbon, sugar, and fresh mint leaves on crushed ice. However, there are many julep recipes.

Rack house or warehouse is the building in which producers age whiskey.
Ricks are the wooden structures on which producers place barrels of whiskey for aging.
Single barrel whiskey is bottled from only one barrel. That is, it’s straight or unblended.
