MASHING
which produces WORT (sugar solution) from ground or crushed MALT.
FERMENTATION
that produces WASH (a weak, crude, impure spirit) consequent upon
the introduction of YEAST in the WORT.
DISTILLATION
that strengthens and purifies the spirit contained in the WASH
and also separates the solids contained in the spirituous liquor.
MATURATION
that transforms the raw SPIRIT into WHISKY.
In
two of the above stages the distiller is concerned with the behaviour
of living organisms. In MALTING
the involvement is the controlled germination of the barley corn
and in FERMENTATION
the action of the yeast when placed in a solution rich in fermentable
sugars and growth factors. All living organisms are susceptible
to conditions of their environment and many of the distiller's problems
arise therefrom.
