Method of Distillation Method 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 sameHeadHeart ( 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.
