WHISKY - FAQ's IV

THE MAKING OF MALT WHISKY

The origins of malt whisky distilling in Scotland are lost in the mists of antiquity. They date back at least to the monks of the 15'" century and probably long before.
Although the distillers' art has been understood since earliest times, the subtle aromas and flavours of whisky have never been fully explained, even today. The ancient term using beatha, which is Gaelic for the Latin aqua vitae or 'water of life', was corrupted in the 18'" century to usky, and then to whisky. The following description is a generalisation of the process.
It should be remembered that each distillery has its own unique specifications.

1. Malting

Best quality barley is first steeped in water and then spread out on malting floors to germinate. It is turned regularly to prevent the build up of heat. Traditionally, this was done by tossing the barley into the air with wooden shovels in a malt barn adjacent to the kiln.
During this process enzymes are activated which convert the starch into sugar when mashing takes place. After 6 to 7 days of germination the barley, now called green malt, goes to the kiln for drying. This halts the germination. The heat is kept below 70°C so that the enzymes are not destroyed. Peat may be added to the fire to impart flavour from the smoke.
2. Mashing

The dried malt is ground into a coarse flour or grist, which is mixed with hot water in the mash tun. The water is added in 3 stages and gets hotter at each stage, starting around 67°C and rising to almost boiling point.
The quality of the pure Scottish water is important. The mash is stirred, helping to convert the starches to sugar. After mashing, the sweet sugary liquid is known as wort. The spent grains - the draff - is processed into cattle feed.
3. Fermentation

The wort is cooled to 20°C and pumped into washbacks, where yeast is added and fermentation begins. The living yeast feeds on the sugars, producing alcohol and small quantities of other compounds known as congeners, which contribute to the flavour of the whisky. Carbon dioxide is also produced and the wash froths violently. Revolving switchers cut the head to prevent it overflowing. After about 2 days the fermentation dies down and the wash contains 6-8% alcohol by volume.
4. Pot Stills

In some mysterious way the shape of the pot still affects the character of the individual malt whisky, and each distillery keeps its stills exactly the same over the years.
In distillation, the still is heated to just below the boiling point of water and the alcohol and other compounds vaporize and pass over the neck of the still into either a condenser or a worm - a large copper coil immersed in cold running water where the vapour is condensed into a liquid.
5. Distillation

The wash is distilled twice - first in the wash still, to separate the alcohol from the water, yeast and residue called pot ale - the solids of which are also saved for use in animal feeds.
The distillate from the wash still, known as low wines, and containing about 20% alcohol by volume, then goes to the spirit still for the second distillation. The more volatile compounds which distil off first - the foreshots, and the final runnings called feints where more oily compounds are vaporized, are both channelled off to be redistilled when mixed with the low wines in the next batch.
Only the pure centre cut, or heart of the run, which is about 68% alcohol by volume is collected in the spirit receiver.
6. Spirit Safe

All the distillates pass through the spirit safe - whose locks were traditionally controlled by the Customs & Excise. The stillman uses all his years of experience to test and judge the various distillates without being able to come into physical contact with the spirit.

The newly distilled, colourless, fiery spirit reduced to maturing strength, 63% alcohol by volume, is filled into oak casks which may have previously contained Scotch whisky, bourbon or sherry, and the maturation process begins. 

WHISKY - FAQ's III

What are the principal by-products of Scotch Whisky?

The liquids and solids remaining after distillation are not wasted, nor are they allowed to pollute rivers or coastlines. In recent years the Scotch Whisky industry has invested heavily in developing methods of treating the residue of distillation so that it now makes an important contribution to the animal foodstuffs industry.
Most distilleries now possess by-products plants or, in the case of smaller distilleries in remote areas, send their waste material to the area plants which process it into dark grains. These are extremely rich in protein and are sold in palletised form to farmers who use them to enrich cattle food.
Grain Whisky distilleries usually recover the carbon dioxide produced during the fermentation stage. This has several applications in industry and in the production of soft drinks.

What is meant by Under Bond and Duty Paid sales, respectively?

(a) Sales Under Bond are sales on which the Excise Duty has not been paid. The goods are consigned to a bonded duty-free warehouse.
(b) Sales Duty Paid are sales on which the Excise Duty has already been paid.
What is the origin of the name 'whisky'?
The term ‘whisky’ derives originally from the Gaelic ‘uisge beatha’, or ‘usquebaugh’, meaning ‘water of life’. Gaelic is that branch of Celtic spoken in the Highlands of Scotland.
When was Scotch Whisky first distilled?

Whisky has been distilled in Scotland for hundreds of years. There is some evidence to show that the art of distilling could have been brought to the country by Christian missionary monks, but it has never been proved that Highland farmers did not themselves discover how to distil spirits from their surplus barley.

The earliest historical reference to whisky comes much later, Mr J Marshall Robb, in his book ‘Scotch Whisky’, says: ‘The oldest reference to whisky occurs in the Scottish Exchequer Rolls for 1494, where there is an entry of ‘eight bolls of malt to Friar John Cor wherewith to make aquavitae’. A boll was an old Scottish measure of not more than six bushels. (One bushel is equivalent to 25.4 kiIograms)
When King James IV was in Inverness during September 1506, his Treasurer’s Accounts had entries for the 15th and 17th of the month respectively: ‘For aqua vite to the King. . .’ and ‘For ane flacat of aqua vite to the King. . .’. lt is probable that the aquavitae in this case was spirit for drinking.
The earliest reference to a distillery in the Acts of the Scottish Parliament appears to be in 1690, when mention is made of the famous Ferintosh distillery owned by Duncan Forbes of Culloden.
There is also a reference to distilling in a private house in the parish of Gamrie in Banffshire in 1614. This occurs in the Register of the Privy Council, where a man accused of the crime of breaking into a private house, combined with assault, was said to have knocked over some ‘aquavitie’.
One of the earliest references to ‘uiskie’ occurs in the funeral account of a Highland laird about 1618.
An unpublished letter of February 1622, written by Sir Duncan Campbell of Glenorchy to the Earl of Mar, reported that certain officers sent to Glenorchy by the King had been given the best entertainment that the season and the country allowed. It stated: ‘For they wantit not wine nor aquavite.’ This ‘aquavite’ was no doubt locally distilled whisky.
Another writer affirms that aquavitae occasionally formed part of the rent paid for Highland farms, at any rate in Perthshire, but no actual date is given for this practice.

What is the history of charging duty on Scotch Whisky?
The Scots Parliament in 1644 passed an Excise Act fixing the duty at 2/8d (13p) per pint of aquavitae or other strong liquor - the Scots pint being approximately one third of a gallon. For the remainder of the 17th century various alterations were made to the types and amounts of duty collected.
After the Union of the Parliaments in 1707, English revenue staff crossed the border to begin their lengthy attempts to bring whisky production under control. Ninety years later the excise laws were in such a hopeless state of confusion that no two distilleries were taxed at the same rate. Illicit distilling flourished, the smugglers seeing no good reason for paying for the privilege of making their native drink.
After a lengthy Royal Commission, the Act of 1823 sanctioned legal distilling at a duty of 2/3d (12p) per gallon for stills with a capacity of more than 40 gallons. There was a licence fee of £10 annually and no stills under the legal limit were allowed. The first distillery came into ‘official’ existence in the following year and thereafter many of the more far-sighted distillers came over on to the side of the law.
In 1840, the duty was 5d (2.5p) per bottle and by the beginning of the First World War it had risen to 1/81/2d (9p). In 1939, a typical bottle of Scotch Whisky cost 14/3d (72p) of which 9/71/2d (48p) was duty. By 1992, after a succession of duty increases, the same bottle was costing around £10.80. The duty on it was £5.55, equivalent to £19.81 per litre of pure alcohol.
In 1995, for the first time in one hundred years, the tax on Scotch Whisky was reduced. Duty fell from £5.77 to £5.54 a bottle (70cl). In 1996, the tax on Scotch Whisky was again reduced.
Since 1973 the price of a bottle of whisky, including the Excise Duty, has been subject to a Value Added Tax.

WHISKY - FAQ's II

What is patent still distillation?

Unlike Malt Whisky, Grain Whisky is distilled in a continuous operation in a Patent Still. This is sometimes known as the Coffey Still, after Aeneas Coffey, who developed it in 1831.

Steam is fed into the base of the analyser and hot wash into the top. As the two meet on the surface of the perforated plates, the wash boils and a mixture of alcohol vapours and uncondensed steam rises to the top of the column. The spent wash runs down and is led off from the base.
The hot vapours enter the rectifier at the base and as they rise through the chambers they partially condense on the sections of a long coil through which wash is flowing. The spirit vapour condenses at the top of the rectifier and is run off through a water-cooled condenser to the spirit safe and on to the spirit receiver. Once the spirit begins to be collected it runs continuously until the end of distillation.
Because of the rectifying element present in this process the distillate is generally lighter in aroma than most Malt Whiskies. It consequently has a milder character and requires less time to mature.

What is the worm?

The worm and its surrounding bath of cold running water, or worm-tub, form together the condenser unit of the Pot Still process of manufacture. The worm itself is a coiled copper tube of decreasing diameter attached by the lyne arm to the head of the Pot Still and kept continuously cold by running water. In it the vapours from the still condense. Fed by the still, it in turn feeds the receiving vessel with the condensed distillate.

The worm is being replaced gradually by the more modern tubular condenser.

What are low wines?

This is the name given to the product of the first distillation in the Pot Still process of manufacture. It is the distillate derived from the wash and contains all the alcohol and secondary constituents and some water. It forms the raw material of the second distillation, which is carried out in the Spirit Still. The feints and foreshots are added to the low wines when the Spirit Still is charged.

What is pot ale?

Pot ale, alternatively burnt ale, is the liquor left in the Wash Still after the first distillation in the Pot Still process. It is the residue of the wash after the extraction by distillation of the low wines.

What are foreshots?

Foreshots is the term applied to the first fraction of the distillate received during the distillation of the low wines in the Spirit Still used in the Pot Still process of manufacture. They form the first raw runnings of this second distillation and their collection is terminated by the judgement of the stillman. The following fraction of the distillate is the potable spirit. The foreshots are returned to the still, together with the feints.

What are feints?

Feints is the name given to the third fraction of the distillate received from the second distillation in the Pot Still process. They form the undesirable last runnings of the distillation. As noted above, they are returned with the foreshots to the Spirit Still when it is recharged with low wines.
The term is also applied to the first and last runnings from the Patent Still, in which process they are returned to the wash for re-distillation.
The feints and foreshots from the last distillation of the season are kept for adding to the first low wines of the succeeding season.

What are spent lees?

Spent lees are the residue in the Spirit Still after the distillation of the foreshots, potable spirits, and feints. They are usually treated and run to waste.


What is draff?

Draff is the spent grain left in the mash-tun after the liquor, wort, has been drawn off. It represents, as a rule, about 25 per cent of the malt and unmalted cereals, if any, put into the mash-tun. Draff enjoys a large market as cattle food. 

WHISKY - FAQ's I

What is a single whisky?
A single whisky is the product of one particular distillery.

What is meant by saccharify?

To saccharify means to convert to sugar. In whisky distilling it refers to the process which takes place during the malting and mash-tun stages by which enzymes in the malt, referred to as diastase, turn the starch in the cereals into sugar ready for the fermenting action of the yeast.

What is diastase?

When conditions of temperature and moisture favour germination, the embryo and associated parts of the barley grain secrete a mixture of enzymes commonly known as diastase. These act to modify and make soluble the starch in the barley, thus preparing it for conversion at a later stage to maltose.

What is wort?

Wort is the liquid drawn off the mash-tun in which the malted and unmalted cereals have been mashed with warm water. Wort contains all the sugars of the malt and certain secondary constituents. After cooling, it is passed to the fermenting vats. In Malt distilleries the cereals are all malted; in Grain distilleries a proportion only is malted, the remainder being unmalted. In some cases, Grain distilleries do not separate off wort, passing the complete mash to the fermentation vessels.

What is wash?

The wort or mash technically becomes wash as soon as yeast is added to start fermentation. However, the term is usually used to refer to the liquid at the end of the fermentation. It is the wash which forms the raw material of the first distillation in the Pot Still process and of the only distillation in the Patent Still process.

What is the pot still distillation?

Malt Whisky is distilled twice - although a few distilleries may undertake a third distillation - in Pot Stills which resemble huge copper kettles.

The spirit is driven off from the fermented liquid as a vapour and then condensed back to a liquid.

In the first distillation the fermented liquid, or wash, is put into the Wash Still, which is heated either directly by fire or by steam-heated coils.

At this stage the wash contains yeast, crude alcohol, some unfermentable matter and the by-products of fermentation. During the process of boiling the wash, changes take place in its constituents which are vital to the flavour and character of the whisky.
As the wash boils, vapours pass up the neck of the still and then pass through a water-cooled condenser or a worm, a coiled copper pipe of decreasing diameter enclosed in a water jacket through which cold water circulates.

This condenses the vapours and the resulting distillate, known as low wines, is collected for re-distilling. The liquor remaining in the Wash Still is known as pot ale or burnt ale and is usually treated and converted into distillers’ solubles for animal feed.
The low wines are distilled again in the Spirit Still, similar in appearance and construction to the Wash Still but smaller because the bulk of liquid to be dealt with is less. Three fractions are obtained from the distillation in the Spirit Still. The first is termed foreshots, the second constitutes the potable spirit, and the third is called feints. The foreshots and feints are returned to the process and redistilled in the Spirit Still with the succeeding charge of low wines. The residue in the still, called spent lees, is run to waste.
In the case of the Spirit Still, the design of the still, the height of the head (or top) of the still and the angle of the wide-diameter pipe or lyne arm, connecting the head to the condensing unit, are all very important and have an effect on the distillate.
The Pot Still has changed little in general design over the centuries.

LOIRE VALLEY WINES - HISTORY OF WINE MAKING

Vines already existed when Romans invaded the Loire Valley.
The legend says that Saint Martin was the first to make wine in the Loire region. It was in 380.
The wine production then grew fast. In both river banks, wine makers made white wine. On the hills, they went for red wine.
Such as in Burgundy, most of the vineyards belong to monasteries and monks had developed the wine production in the whole region.

Is consuming Wine daily good for health?

 The idea of consuming wine daily, particularly red wine, has been a topic of interest for many years, with some studies suggesting potentia...
