Q

How does water temperature affect the flavor of the spirit?

A

The temperature of the water in the condenser affects how long the vapor will be in contact with the copper

Since copper is a purifier and warmer water causes it to take longer for the vapour to liquify, the extended copper contact creates a purer and lighter spirit

Colder water will do the opposite and will yield a heavier, more “traditional” spirit

  • The temperature must be kept below 60º C or else the phenols in the peat will be destroyed
  • These phenols only adhere to the barley when they are still damp, so you want smoke, rather than heat, at this stage
  • The lower the temperature, the higher the peatiness
102
Q

How is heat drawn out of the kiln?

A

Through a tapering roof

103
Q

Describe the free drying phase of kilning.

A

This stage evaporates moisture on the surface of the green malt. Air is drawn through the malt at a temperature of 60-65ºC (140-149ºF). Peat, if used, will be added at this phase and the temperature should be below 60ºC (140ºF).

104
Q

Describe the forced drying phase of kilning.

A

Temperature is increased 70-75ºC (158-167ºF) and the airflow is decreased. The moisture content of the malt will now have decreased by 5%

105
Q

Describe the cooling phase of kilning.

A

The temperature is reduced to 30ºC (86ºF) to prevent further curing of the malt

  • The entire kilning process takes between 20 and 48 hours, depending on the type of kilning, the size of the kiln, and the amount of malt
106
Q

What is peat?

A

Acidic, decayed vegetation made from bog plants, such as sphagnum moss, heather, sedges, and grasses

  • For peat to develop there must be high rainfall, a cold atmosphere, and poor soil draining or aeration
  • The waterlogged ground cannot break down the vegetation, so a thickening layer of peat develops
107
Q

How is peat cut?

A

Peat is cut in May/June, then laid out on the heather around the pet bank for 2 weeks, then stacked in small pyramids, “cas bhic”, Gaelic for “little feet”, to dry thoroughly for a year

108
Q

Describe Lowland peats.

A

Looser, softer texture, containing more vegetable matter

  • Burn more rapidly and give off more dust
109
Q

In Orkney, what are “fog”, “yarphie”, and “moss” peats?

A

Fog: the rooty top layer
Yarphie: the small roots
Moss: the deepest, darkest layer – best for heat, but not smoke

110
Q

How is the intensity of peating categorized?

A

3 categories: lightly peated, medium peated, and heavily peated

Lightly peated: 1-5 ppm total phenols
Medium: 10-20 ppm total phenols
Heavily: 30-50 ppm total phenols

111
Q

What is the “culm”?

A

Withered shoots of the malted barley

112
Q

What is the malt tested for at the distillery prior to milling?

A
  1. Moisture: 12% maximum permitted
  2. Viability of germination: must be 99% viable
  3. Insect infestation: this can destroy a hopper-full in hours
  • The malt is then screened to remove any reamining dust, stones, and small grains
113
Q

What does it mean when a malt has been “dressed”?

A

Passed over a reverberating wire-mesh that removes the “culm” and rootlets produced during malting

114
Q

How is grist made?

A

In a mill hopper
• Malt is loaded in hundredweight (50kg) lots
• Mill has two sets of rollers: one to crack the husks, one to grind the malt
• It must produce 10% flour, 20% husk, and 70% grist

  • If it is too fine, the mash tun will not drain quickly enough
    If it is too coarse, the liquor will drain too fast and maximum extraction will not occur
115
Q

What is the first things that happens in a mash tun?

A

The grist is mashed with hot water in order to extract the maximum amount of soluble starch

116
Q

What is a mash tun?

A

A large circular vessel with perforated floors through which “worts” can drain after mashing is complete

  • Usually covered, often with copper, to retain heat and is made from stainless steel or cast iron
117
Q

How is the mash stirred?

A

Revolving mechanical rakes periodically stir the mash

118
Q

What is the size of a mash tun?

A

Varies from 1 to 15 tonnes

  • The size is related to the capacity of the fermentation vessel it will later fill
  • 1 tonne of malt should produce 5.000 litres of wort
119
Q

What is a Lauter tun?

A

A German invention, widely used by brewers, designed to increase extraction

  • Most distilleries have adopted this tun
120
Q

How many waters (“extractions”) are used in the mashing process?

A

3

  • The first includes the third water leftover from the previous mashing
121
Q

Describe the process of the three waters of the mashing process.

A

1st: heated to around 63-64ºC (147ºF), then mixed with the grist in a mashing machine and filled into the mash tun. If the water is too hot, it will kill the enzymes; if it is too cool, the amount of grist will have to be reduced.
2nd: water is pumped into the mash tun, this time at 70ºC (158ºF), stirred, left for 30 minutes, then emptied into the under back.
3rd: the “sparge”. Goes into the mash tun at 85ºC (185ºF), takes 15 minutes to fill and settles, then is pumped into the hot water tank to be used as the first water of the next mashing. This contains about 1% sugar.

122
Q

What happens to the wort after the mashing process?

A

The warm wort is then passed from the under back through a heat exchanger to reduce the temperature to below 20ºC (68ºF).

  • If the wort is not cooled, the maltose will decompose and the yeast will be killed off
123
Q

What is a “pot ale”?

A

Residues of wash still distillation

  • Combined with draff at a dark grains plant to be compressed into a “cattle-cake”
124
Q

What happens to the worts after being chilled in a heat exchanger?

A

The chilled worts are pumped into the washback (fermentation vessel)

125
Q

After the washback is initially filled, about 2/3 full with wort for fermentation, what happens?

A

Yeast is pitched in, usually as the worts enter the back

  • The worts from now on become the wash
126
Q

Describe the first phase of fermentation.

A

The “log phase” typically lasts a couple hours and the yeast gets used to its surroundings

127
Q

Describe the second phase of fermentation.

A

During the second phase, yeast cells rapidly multiple, consuming the sugars in the wash and turn the mixture into CO2 and alcohol.

This causes the wash to seethe and froth.

The temperature of the wash increases to 35ºC (95ºF).

128
Q

Describe the third (final) phase of fermentation.

A

The final phase lasts about 12 hours and the wash calms down as the alcohol inhibits the activity of the yeasts cells.

The growth of bacteria dramatically increases; this bacteria growth makes a second, bacteriological, fermentation possible.
• The bacteria come mainly from the malt and are basically lactic acid
• Lowering the pH, these lactic acids allow further flavors to develop

129
Q

How often are washbacks cleaned?

A

After each fermentation, as excessive bacterial infestation can render yeasts useless

130
Q

In simple terms, what is distillation?

A

Distillation separates the alcohol in the wash from the water and concentrates it

131
Q

Q

How do direct-fired pot stills prevent solids from sticking to the bottom and burning?

A

They are fitted with “rummagers”, revolving arms that drag heavy, copper, chain-mail around their bases

135
Q

What are rummagers?

A

Revolving arms that drag heavy, copper, chain-mail around the bases of direct-fired pot stills

136
Q

How does a narrow neck of a copper pot still affect the flavors of the spirit?

A

A narrow neck will increase the velocity of the ascending caper and reduce contact with the copper, thus being less pure

137
Q

After fermentation, the wash is pumped from the washback to the wash charger, then to the wash still. What happens next?

A

First distillation

138
Q

What does the first stage of distillation accomplish?

A

It extracts alcohol from the wash

139
Q

Describe the first distillation.

A

The wash is heated, comes to a boil, then begins to froth up within the vessel.

As soon as the froth is visible in the sight glass, the heat is reduced.

The wash then settles, then the heat is gradually increased. This process is repeated a few times to “break the head” of the froth, then steadily distills off the low wines.

140

A

8

141
Q

A

3-4

  • They are deemed to be “exhausted” or “spent”
163
Q

What is “de-char/re-char”?
