Congeners – natural flavor parts in spirits. Made up of trace oils, esters and acids carried through the distillation process. Spirits distilled at higher proofs are practically free of congeners, whereas low proofs have a high concentration.
Continuous Still – is virtually standard equipment of all distilleries. Also known as the “Coffee Still.” The continuous still appearance is that of a tall cylinder and usually rises through two or three stories of the distillery building. The inner works of the still is fitted with numerous horizontal, perforated baffle plates. The distillation process is accomplished by pumping the pre-heated liquid mash to the top of the still and permitting it to splash down through the baffle plates. At the same time, steam is entered at the bottom of the still and rises through the baffle plates. In constant contact with the mash, the steam distills and re-distills the liquids as it rises. The proof may be stepped up at each higher level between the plates. The vaporized alcohol finally passes off through the top of the still where it is cooled and condensed as new spirits. The spent liquids during the process drop to the bottom of the still and are drawn off to be converted into distiller’s grains.
Converter – Equipment in which grain mash, mixed with water and malt are cooked. Best example would be a giant pressure cooker. In this process the enzymes of the malt convert the grain starch to sugar.

Distilling – Separation of alcohol from a substance by vaporization and condensation. All distilled spirits are made from a liquid, fermented mash or other substance. The fermented mash or substance can be made from grapes, sugar cane, grain or any starch product (sugar beet, potato). Fermentation converts the sugar content to alcohol. Distillation separates the alcohol and congeners from the undesirable liquids and solids that make up a fermented substance. Note, that in distillation every liquid has a unique boiling point. Alcohol for instance boils and vaporizes at 173 degrees. Whereas water boils and vaporizes as steam at 212 degrees. When a fermented substance is heated to a temperature of 173 degrees it alcoholic content begins to boil and vaporize leaving most of the rest of the substance behind. Congeners are carried along with the vaporized alcohol in distilling. The congeners are what differentiate distillates of grain mash, sugar cane or grapes; whiskey, rum and brandy. Distillers have adopted controls to enhance or change styles of distilled products. The type of still, whether a continuous still or pot still; the amount of heat; the proportion of the run accepted or rejected as to the heads and tails along with the pre-determined proof of the distillate.

Egg Nog – Liquid custard that is made up of eggs, cream and sugar combined with Brandy, Rum or Bourbon.
Enzymes – A naturally occurring, complex organic substance that has the property of causing changes to take place in other substances. The enzymes of malt, for example, change the natural starch content of grain to sugar.
Excise Tax – a tax levied by the United States government on distilled spirits, wines and malt beverages. The excise tax is a specific tax computed either on the basis of the alcoholic content of the taxed beverage or on a wine gallon basis.
Feints (pronounced “Faints”) – A name given to the last portion of spirits that runs from a still as the distillation of a batch nears completion. Feints are normally turned back into the still for redistillation. Feints are also, and more generally referred to as tails.
Fermentation – A natural reaction of yeast as it grows and multiplies in a batch of grain, sugar cane or fruit / vegetable mash is known as fermentation. In the process, the sugar content of the mash is converted to alcohol. In whiskey making two methods of fermentation are employed. Sour Mash: part of the previous day’s fermented batch of mash is added to each fresh batch of mash. Adds more yeast to the new mash, while at the same time provides continuity with each batch. This process takes longer. From 3 to 4 days; requires a larger plant; greater care; and the yield of whiskey per bushel of grain is lower. It is costlier, but is the primary standard procedure among straight whiskey distillers. Sweet Mash: fermentation is started with newly cultured yeast; usually process takes 2 to 3 days. This type of process is seldom utilized.

Gin – An alcoholic beverage delicately flavored with juniper berries and other botanicals. Most gin is distilled from grain by continuous process. Still is fitted with a gin head, packed with the flavoring agents (juniper / botanicals), and through, which the alcohol vapors, pass as they rise from the still. Federal regulations forbid the artificial coloring of dry gin unless the nature of the coloring is stated on the label. Some gins straw yellow color is derived from aging in barrels, thus it is obtained naturally. The distillation of juniper berries with spirits originated in Holland. The product was called Genevre, a French word-meaning juniper. The English shortened the word to gin. Dutch gins today are heavy bodied, strongly flavored and go under the name of Geneva Gin, and also under the names of Holland’s and Schiedam gins. English gin accounts for most of the U.S. imports.
