Pot and Column Stills (O-1)

Question 1

Most pot stills are made from _____ because?

Answer 1

-Copper
-Great heat conductor and easy to shape

Question 2

Most modern pot stills are heated using?

Answer 2

Stream
•internal steam coils
OR
•External steam jacket

Question 3

The POT in a pot still has has what function?

Answer 3

Holds the liquid that will be distilled

Question 4

What is the SWAN NECK of a pot still?

Answer 4

A section of tubing between the pot and still head

Question 5

What is the STILL HEAD in a pot still?

Answer 5

The top of the swan neck

Question 6

What is the function of the the LYNE ARM?

Answer 6

Tubing that links the still head to the condenser

Question 7

What is the purpose of the CONDENSER in a pot still?

Answer 7

It converts the vapor back into a liquid

Question 8

How does a shell and tube condenser work? And what spirit uses it?

Answer 8

Vapor enters at the top, comes in contact with a coolant tube (water) that causes vapor to condense back into a liquid that flows from the bottom
•Cognac

Question 9

Between a worm tub or shell and tube, which one is most commonly seen today?

Answer 9

Shell and tube

Question 10

A fermented alcoholic liquid has to be distilled at least __in order to produce a spirit?

Answer 10

2 times out of

Question 11

Which still is a batch process that produces low rectification with a medium to pronounced aroma?

Answer 11

Pot still

Question 12

What is the aim of the first distillation?

Answer 12

•Remove some water and other non volatile liquid waste
•Distill and collect volatile liquid from 10% ABV to 25-30% (Low Wines)

Question 13

What are the basic steps of how first distillation works?

Answer 13

1. 10% ABV ethanol+water
2. Boiled & vapors rise up into condenser
   3.Flows until 1%ABV and low wines are collected (25-30% ABV)
3. Liquid remaining is discarded

Question 14

What is the aim of second distillation?

Answer 14

Create a liquid the distiller can sell by selecting and concentrating Group 2 fractions (ethanol and fractions with similar boiling point)

Question 15

What are steps in 2nd distillation?

Answer 15

1. Distill low wines with heads and tails from previous batch
2. Boiled and condensed
3. Selections over time
   1.Heads (concentrated group 1 factions
   2.Heart (75% ABV concentrated group 2 factions
   3.Tails (concentrated group 3 factions)
4. Discard waste

Question 16

What is the order in which liquid is captured in 2nd distillation?

Answer 16

1. Heads (Group 1 fractions)
2. Heart (75% ABV concentrated group 2 fractions
3. Tails (Concentrated group 3 fractions)

Question 17

What are the parts of a Column Still?

Answer 17

•Steam heat source
•Plates (all have in common)
•Downcomer
•Bubble Cap

Question 18

What is the aim of using plates in a column still? And how does it work?

Answer 18

maximize reflux
•Vapor forced through bubble cap onto plate
•Greater concentrations rise and less volatile fall.

•

Question 19

What is the aim of continuous distillation?

Answer 19

Managing the flow of liquid and vapor through the still to keep collecting spirit with consistency still and quality.

Question 20

Column Still Distillation steps:

Answer 20

1. Constant pre-heated alcoholic liquid enters bottom half of still
   2.constant flow of vapor rising and liquid falling
   •Group 1 fractions: (lower boiling point than ethanol) will flow out as heads
   •Group 2 Heart will be selected a few plates below Heads
   •Group 3 (higher boiling points than ethanol) drained off lower plate as tails.
2. Waste removed
