process of distilling that uses materials from an older batch of mash to start fermentation. all bourbon is made with sour mash.
a device consisting of a rotating shaft within a cylinder to carry grain from one place to the other
A tank where grist is soaked in water and heated in order to convert the starch to sugar.
A mill for grinding grain.
a fermentation vessel that allows the yeast strains
to convert the wort into a fermented liquid called WASH
the first still in which the wash is concentrated from 7-8 abv to 25 abv
a large, padlocked, glass walled, usually brass bound container found at Scotch whisky distilleries which allows the distiller to analyse and manage the spirit coming out of the pot still without coming into contact with the spirit itself
Vessel to collect spirit before filling casks.
Uses steam to distill in single batch operations
Condenses hot vapors into liquids
The coiled copper tube along which vapors condense in a still.
Device that passes current easily in one direction, but very little in the other
'strips' light material out of it by applying heat, and sometimes returning the cooled distillate (tops product) into the column to further purify the bottoms product, removing more incremental light material from the bottoms
A ____ column is able to separate a mixture into its two parts through a series of vaporization-condensation steps.
A weir on the tray ensures that there is always some liquid (holdup) on the tray and is designed such that the the holdup is at a suitable height, e.g. such that the bubble caps are covered by liquid.
Between each tray is a ______, a device for liquid to flow from one tray to another.
liquid vaporizes in column, it passes through many trays, mounted on risers on the liquid covered trays, lift to allow a small amount of vapor through, vapor contact liquid on tray, transfer some heat energy
A big container full of liquid culture medium, which microorganisms can grow and reproduce in. Fermenter is sterilised using steam to prevent other microorganisms growing. Incoming nutrients are heat sterilised and the air supply is filtered. Then harvested and purified.
