    • DefinationDefination • Spirit is defined as product of distillation of fermented beverage.
    • DistillationDistillation • 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 after fermentation. • 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 distillation. • 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 Head Heart ( 30% Alcohol remaining water) Tail •
    • Cont..Cont.. • 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 Head Heart ( 70% alcohol remaining water) Tail
    • Cont..Cont.. • 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 operation.
