Jargon File

At my first job in a research laboratory, the first thing that was handed to me was a sheet called the “Jargon File” and it was a list of unique words and acronyms specific to the job. That sheet of paper gave me a jump start into the job and every time someone used an acronym for a test or piece of equipment, I wasn’t lost, I knew exactly what they were talking about and my job performance was better for it.

Every industry has their word list and shot-forms and without knowing these terms you can feel a bit out of place. To solve that problem, here is the jargon file for distilling. Look at it and refer to it as needed.

Distillation Jargon File

Aldehyde: 

Attenuation: the degree to which yeast will consume the sugars in the wort or must. Low rates mean a low conversion to alcohol, which is inefficient for distillation purposes.

Azeotrope: a mixture of two or more liquids whose proportions cannot be altered or changed by simple distillation, in our case this will be the point where ethanol and water cannot be separated any further which is at 95.63% ethanol and 4.37% water-mark.

Boiler: When the liquid is heat; also a piece of equipment used to create steam

Condenser: 

Congener

Ester

Ethanol: the drinking alcohol we strive to purify in our distillation process

EtOH: a short form for ethanol

Helmut:

Ketone:

Likker: a trendy lowbrow term used by “moonshiners” and wannabe moonshiners to describe liquor.

Lyne Arm (Swan Arm)

Marc:

MeOH: a short form for methanol

Parrot:

Pot Ale:

Proof: Though measuring alcohol in degrees proof is antiquated and mostly abandoned, it is still used for marketing purposes and by people unwilling to accept change. Depending on where you live proof can mean different things. In the UK it was equal to 57.1% ABV and in the US it is 50% ABV.

Saccharification:

Spent Lees: 

Thumper (Reflux Drum):
