The Whisky Distilleries of the United KingdomThe following is from The Whisky Distilleries of the United Kingdom by Alfred Barnard: Glen Grant
The barley, most of which is grown in the fine county of Moray, is received at the doors of the Granaries, and conveyed by elevators to the different barley- lofts. Two of the Granaries are splendid three-decker buildings, of solid stone, and slate roofed; the ground floors are concreted for Malting, each having a stone Steep with the usual draining arrangements. The No. 3 buildings, used for the same purpose, are larger, but not quite so long. Contiguous is the Kiln, 58 feet long by 20 feet wide, with wire flooring, heated by peat and coke in two open chauffeurs. It is capable of drying 50 quarters in 24 hours. The Malt Deposit adjoins the Kiln, at a lower elevation. The malt falls through a shoot, of same five feet in length, direct to the Malt Deposit, which holds about 3,000 bushels, and thence to the Mill underneath, where it passes through a powerful set of rollers or crushers. After the Malt is ground it falls by gravitation into the Hopper over the Mash House, through the Mashing Machine into the Tun below, which has the usual rotary stirring gear. This Mash Tun is a circular vessel, 18 feet in diameter, 5 feet deep. The Worts are drained off from this vessel by three huge cocks into the Underback, which has a capacity of 1,200 gallons. After this the Worts are pumped up into the Receiver, contiguous to the Tun Room. They then go through a Morton's Refrigerator, thence by gravitation to the Washbacks of which there are eight, each containing 7,000 gallons. The Worts rise from the bottom of these vessels, and as soon as they reach the proper temperature a certain proportion of yeast is added. Fermentation then takes place, and as the froth rises, revolving switchers, driven by a small steam-engine, break it up and prevent it from overflowing. Now commences the interesting part of the process the liquor changes its name and is called wash, and is run off through close copper pipes into the Jackback, a timber vessel let into the floor of the Mash House. From the Jackback the wash is pumped into the Wash Charger, which holds 6,000 gallons, whence it runs by gravitation into two Wash Stills~ holding 5,000 gallons and 2,500 gallons respectively. A small water-wheel, propelled by the waste water from the Worm Tub, turns the rummagers in the Wash Stills, all of which are of the Old Pot kind. These rummagers prevent the sediment of the Wash from settling down to the bottom of the Stills, while preventing at same time the danger of the Stills being burned. We noticed a purifier attached to the head of each Still, consisting of a copper vessel with a water basin at the top, which effectually prevents anything but the purest steam from passing, all impurities being gent back into the Still. There are above the Stills, on an elevated gallery, two upright condensers. From the Wash Stills the spirit goes through the condensing worms, which coil through a concrete exterior Malt House tank, 24 feet long and 8 feet I deep. The water in this tank is supplied from a constant stream brought from an aqueduct erected on the side of the hill above the Distillery. There is also another Worm Tub, a huge square vessel, lower down, supplied from the same source. From the Worm the spirit flows through the Safe into the Low-wines and Feints Receiver, whence it is pumped up into the Low-wines and Feints Charger above; whence again it flows into the two Spirit Stills, each holding 2,500 gallons and 1,600 gallons. The same process is repeated as before described, except that the pure spirit, after passing through the Safe, falls into the Spirit Receiver, which is in the Running Room. Of course the reader will understand that the impure, or feints Spirits, go back into the Still to be re-distilled. From the Receiver the Whisky is pumped into a Vat in the Spirit Store which holds 2,500 gallons. We may here remark that the Still House is a most substantial building, with iron roof, and girders of the same material. The heaters, or coppers, holding 6,000 gallons and 4,500 gallons respectively, are heated by steam. In the boiler-house we noticed two boilers, 18 feet long by 5 feet in diameter, each possessing steam-domes. In the engine-house are two fine engines, one horizontal of 14 horse-power, the other one a vertical of 24 horse-po\'1er, for driving a dynamo, the electric light being laid all over the premises, for the first time in any manufacturing place in the North of Scotland; it is also laid over the whole of Major Grant's residence. The chimney-shaft is 100 feet high, but looks dwarfed by the background of the steep wooded hill, twenty yards distant. There are thirteen Warehouses on the premises, of enormous size, five of them having two floors, and several of them being 21 feet long and 31 feet wide. They are alt stone buildings, and slated. Some idea of their size may be obtained by the fact that they contained over 500,000 gallons of Whisky, nearly all of which lies to the order of customers. The arrangements for prevention of fire are very complete, and consist of hydrants, with water supply, and hose to carry same allover the premises, assisted by a portable fire-engine which is kept on the works. Capital offices for the Managing Brewer, Clerks, and Excise Officers, have been provided. The following industries are to be found on the premises - a Cooperage, Smithy, Carpentry, and Engineers and Fitters' shop, &c., whilst in the yard, at the back of the Distillery, we saw large stacks of peat, sufficient for two winters consumption, and stacks of ice, for summer use, covered with sawdust and thatched with straw. There is fine stabling for eight horses, and a capital farm-steading, where large numbers of cattle are red on the draff and spent wash. The water, used for distilling, is brought some miles from a mountain spring, and the Glen Grant burn supplies the driving power supplemented by the engines. The make is pure Highland Malt, and the distilling power is 4,500 gallons per week, or 234,000 gallons a year. The output for 1883-4 was 172,917 gallons for 1884-5, 140,370 gallons. The Whisky is gold principally in England, Scotland, and the Colonies, and commands a high price in the market, alike for use by itself and for blending. "WHISKY" |
