Introduction to SpiritIntroduction to Spirit
• Spirit is defined as product of distillation of
• Distillation is the process of separation of
two miscible liquids by using difference in
their boiling point. In present context the
alcohol has to be separated from water
• The evaporating temp. of ethyl alcohol is
78.5C where as for water is 100C.
Method of DistillationMethod of Distillation
• Traditionally there are two method of
• Pot still
• Patent still/ Coffey still/ Continuous still.
Pot still DistillationPot still Distillation
• The pot is made from Copper
• Size differ from place to place
• Alcohol vaporize at 78.5 c
• The Vapours passes through Condenser and
converted to liquid
• Liquid alcohol is collected into three parts
Heart ( 30% Alcohol remaining water)
• The head & tail is collected in a separate vessel.
• The head contains a lot of methyl alcohol & not
suitable for consumption.
• The head & tail are put back for re distillation
with a fresh batch of alcohol water mixture.
• The heart will be taken for a second distillation.
The will also produce the same
Heart ( 70% alcohol remaining water)
• The spirit produced by this method
contains lot of congener element, which
contributes to flavour & body of spirit.
• Spirit, which produced, is Scotch malt
whisky, Cognac, Dutch gin, Dark Rum,
Tequila & some Polish vodka.

Patent Still/Coffey/ContinousPatent Still/Coffey/Continous
• This is also known as Coffey still because
Mr. Aneas Coffey patented it in 1830.
• Aneas Coffey patented an improvement
on an already existing model of which was
developed by Robert Stein.
• This is also known as a continuous still
because the entire process of distillation
gets completed in one continuous
