Part 5
Dr. Guyot's system of roofing the vines with straw matting, to protect them alike against frost and hailstorms, is very generally followed in low situations in the Champagne, the value of the wine admitting of so considerable an expense being incurred. This matting, which is about a foot and a half in width, and in rolls of great length, is fastened either with twine or wire to the vine stakes, and it is estimated that half-a-dozen men can fix nearly 11,000 yards of it, or sufficient to roof over 2½ acres of vines, during an ordinary day.
Owing to the system of cultivation by rejuvenescence, and the constant replenishing of the soil by well-compounded manures, the Champenois winegrowers entertain great hopes that their vineyards will escape the ravages of the phylloxera vastatrix. According to Dr. Plonquet of Ay they are already the prey of no less than fifteen varieties of insects, which feed upon the leaves, stalks, roots, or fruit of the vines. Between 1850 and 1860 the vineyards of Ay were devastated by the pyrale, a species of caterpillar, which feeds on the young leaves and shoots until the vine is left completely bare. The insect eventually becomes transformed into a small white butterfly, and deposits its eggs either in the crevices of the stakes or in the stalks of the vine. All the efforts made to rid the vineyards of this scourge proved ineffectual until the wet and cold weather of 1860 put a stop to the insect's ravages. More recently it has been discovered that its attacks can be checked by sulphurous acid.

The special characteristic of champagne is that its manufacture only just commences where that of other wines ordinarily ends. The must flows direct from the press into capacious reservoirs, whence it is drawn off into large vats, and after being allowed to clear, is transferred to casks holding some forty-four gallons each. Although the bulk of the new-made wine is left to repose at the vendangeoirs until the commencement of the following year, still when the vintage is over numbers of long narrow carts laden with casks of it are to be seen rolling along the dusty highways leading to those towns and villages in the Marne where the manufacture of champagne is carried on. Chief amongst these is the cathedral city of Reims, after which comes the rising town of Epernay, stretching to the very verge of the river, then Ay, nestled between the vine-clad slopes and the Marne canal, with the neighbouring village of Mareuil, and finally Avize, in the centre of the white grape district southwards of Epernay. Châlons, owing to its distance from the vineyards, would scarcely draw its supply of wine until the new year. The first fermentation lasts from a fortnight to a month, according as to whether the wine be _mou_--that is, rich in sugar--or the reverse. In the former case fermentation naturally lasts much longer than when the wine is _vert_ or green. This active fermentation is converted into latent fermentation by transferring the wine to a cooler cellar, as it is essential it should retain a large proportion of its natural saccharine to ensure its future effervescence. The casks have previously been completely filled, and their bungholes tightly stopped, a necessary precaution to guard the wine from absorbing oxygen, the effect of which would be to turn it yellow and cause it to lose some of its lightness and perfume. After being racked and fined, the produce of the different vineyards is now ready for mixing together in accordance with the traditional theories of the various manufacturers, and should the vintage have been an indifferent one a certain proportion of old reserved wine of a good year enters into the blend.
The mixing is usually effected in gigantic vats holding at times as many as 12,000 gallons each, and having fan-shaped appliances inside, which, on being worked by handles, ensure a complete amalgamation of the wine. This process of marrying wine on a gigantic scale is technically known as making the _cuvée_. Usually four-fifths of wine from black grapes are tempered by one-fifth of the juice of white ones. It is necessary that the first should comprise a more or less powerful dash of the finer growths both of the Mountain of Reims and of the River, while, as regards the latter, one or other of the delicate vintages of the Côte d'Avize is essential to the perfect _cuvée_. The aim is to combine and develop the special qualities of the respective crûs, body and vinosity being secured by the red vintages of Bouzy and Verzenay, softness and roundness by those of Ay and Dizy, and lightness, delicacy, and effervescence by the white growths of Avize and Cramant. The proportions are never absolute, but vary according to the manufacturer's style of wine and the taste of the countries which form his principal markets. The wine at this period being imperfectly fermented and crude, the reader may imagine the delicacy and discrimination of palate requisite to judge of the flavour, finesse, and bouquet which the _cuvée_ is likely eventually to develop.
These, however, are not the only matters to be considered. There is, above everything, the effervescence, which depends upon the quantity of carbonic acid gas the wine contains, and this, in turn, upon the amount of its natural saccharine. If the gas be present in excess, there will be a shattering of bottles and a flooding of cellars; and if there be a paucity the corks will refuse to pop, and the wine to sparkle aright in the glass. Therefore the amount of saccharine in the _cuvée_ has to be accurately ascertained by means of a glucometer; and if it fails to reach the required standard, the deficiency is made up by the addition of the purest sugar-candy. If, on the other hand, there be an excess of saccharine, the only thing to be done is to defer the final blending and bottling until the superfluous saccharine matter has been absorbed by fermentation in the cask.
The _cuvée_ completed, the blended wine, now resembling in taste and colour an ordinary acrid white wine, and giving to the uninitiated palate no promise of the exquisite delicacy and aroma it is destined to develop, is drawn off again into casks for further treatment. This comprises fining with some gelatinous substance, and, as a precaution against ropiness and other maladies, liquid tannin is at the same time frequently added to supply the place of the natural tannin which has departed from the wine with its reddish hue at the epoch of its first fermentation.
The operation of bottling the wine next ensues, when the Scriptural advice not to put new wine into old bottles is rigorously followed. For the tremendous pressure of the gas engendered during the subsequent fermentation of the wine is such that the bottle becomes weakened and can never be safely trusted again. It is because of this pressure that the champagne bottle is one of the strongest made, as indicated by its weight, which is almost a couple of pounds. To ensure this unusual strength it is necessary that its sides should be of equal thickness and the bottom of a uniform solidity throughout, in order that no particular expansion may ensue from sudden changes of temperature. The neck must, moreover, be perfectly round and widen gradually towards the shoulder. In addition--and this is of the utmost consequence--the inside ought to be perfectly smooth, as a rough interior causes the gas to make efforts to escape, and thus renders an explosion imminent. The composition of the glass, too, is not without its importance, as a manufactory established for the production of glass by a new process turned out champagne bottles charged with alkaline sulphurets, and the consequence was that an entire _cuvée_ was ruined by their use, through the reciprocal action of the wine and these sulphurets. The acids of the former disengaged hydrosulphuric acid, and instead of champagne the result was a new species of mineral water.
Most of the bottles used for champagnes come from the factories of Loivre (which supplies the largest quantity), Folembray, Vauxrot, and Quiquengrogne, and cost on the average from 28 to 30 francs the hundred. They are generally tested by a practised hand, who, by knocking them sharply together, professes to be able to tell from the sound that they give the substance of the glass and its temper. The washing of the bottles is invariably performed by women, who at the larger establishments accomplish it with the aid of machines, sometimes provided with a revolving brush, although small glass beads are more generally used by preference. After being washed every bottle is minutely examined to make certain of its perfect purity.

With the different champagne houses the mode of bottling the wine, which may take place any time between April and August, varies in some measure, still the _tirage_, as this operation is called, is ordinarily effected as follows:--The wine is emptied from the casks into vats or tuns of varying capacity, whence it flows through pipes into oblong reservoirs, each provided with a row of syphon taps, on to which the bottles are slipped, and from which the wine ceases to flow directly the bottles become filled. Men or lads remove the full bottles, replacing them by empty ones, while other hands convey them to the corkers, whose guillotine machines are incessantly in motion; next the _agrafeurs_ secure the corks by means of an iron staple, termed an agrafe; and then the bottles are conveyed either to a capacious apartment aboveground, known as a cellier, or to a cool cellar, according to the number of atmospheres the wine may indicate. It should be explained that air compressed to half its volume acquires twice its ordinary force, and to a quarter of its volume quadruple this force--hence the phrase of two, four, or more atmospheres. The exact degree of pressure is readily ascertained by means of a manometer, an instrument resembling a pressure gauge, with a hollow screw at the base which is driven through the cork of the bottle. A pressure of 5¾ atmospheres constitutes what is styled a "grand mousseux," and the wine exhibiting it may be safely conveyed to the coolest subterranean depths, for no doubt need be entertained as to its future effervescent properties. Should the pressure, however, scarcely exceed 4 atmospheres, it is advisable to keep the wine in a cellier aboveground that it may more rapidly acquire the requisite sparkling qualities. If fewer than 4 atmospheres are indicated it would be necessary to pour the wine back into the casks again, and add a certain amount of cane sugar to it, but such an eventuality very rarely happens, thanks to the scientific formulas and apparatus which enable the degree of pressure the wine will show to be determined beforehand to a nicety. Still mistakes are sometimes made, and there are instances where charcoal fires have had to be lighted in the cellars to encourage the effervescence to develop itself.
The bottles are placed in a horizontal position and stacked in rows of varying length and depth, one above the other, to about the height of a man, and with narrow laths between them. Thus they will spend the summer providing all goes well, but in about three weeks' time the process of gas-making inside the bottles is at its height, and may cause an undue number of them to burst. The glucometer notwithstanding, it is impossible to check a certain amount of breakage, especially when a hot season has caused the grapes, and consequently the raw wine, to be sweeter than usual. Moreover when once _casse_ or breakage sets in on a large scale, the temperature of the cellar is raised by the volume of carbonic acid gas let loose, which is not without its effect on the remaining bottles. The only remedy is at once to remove the wine to a lower temperature when this is practicable. A manufacturer of the pre-scientific days of the last century relates how one year, when the wine was rich and strong, he only preserved 120 out of 6,000 bottles; and it is not long since that 120,000 out of 200,000 were destroyed in the cellars of a well-known champagne firm. Over-knowing purchasers still affect to select a wine which has exploded in the largest proportion as being well up to the mark as regards its effervescence, and profess to make inquiries as to its performances in this direction.
It is evident that in spite of the teachings of science the bursting of champagne bottles has not yet been reduced to a minimum, for whereas in some cellars it averages 7 and 8 per cent., in others it rarely exceeds 2½ or 3. In the month of October, the first and severest breakage being over, the newly-bottled wine is definitively stacked in the cellars in piles from two to half-a-dozen bottles deep, from six to seven feet high, and frequently a hundred feet or upwards in length. Usually the bottles remain in their horizontal position for about eighteen or twenty months, though some firms, who pride themselves upon shipping perfectly matured wines, leave them thus for double this space of time. All this while the temperature to which the wine is exposed is, as far as practicable, carefully regulated; for the risk of breakage, though greatly diminished, is never entirely at an end.
[Illustration]
By this time the fermentation is over, but in the interval, commencing from a few days after the bottling of the wine, a loose dark-brown sediment has been forming which has now settled on the lower side of the bottle, and to get rid of which is a delicate and tedious task. The bottles are placed _sur pointe_, as it is termed--that is to say, slantingly in racks with their necks downwards, the inclination being increased from time to time to one more abrupt. The object of this change in their position is to cause the sediment to leave the side of the bottle where it has gathered; it afterwards becomes necessary to twist and turn it, and coagulate it, as it were, until it forms a kind of muddy ball, and eventually to get it well down into the neck of the bottle, so that it may be finally expelled with a bang when the temporary cork is removed and the proper one adjusted. To accomplish this the bottles are sharply turned in one direction every day for at least a month or six weeks, the time being indefinitely extended until the sediment shows a disposition to settle near the cork. The younger the wine the longer the period necessary for the bottles to be shaken, new wine often requiring as much as three months. Only a thoroughly practised hand can give the right amount of revolution and the requisite degree of slope; and in some of the cellars that we visited men were pointed out to us who had acquired such dexterity as to be able at a pinch to shake with their two hands as many as 50,000 bottles in a single day.
Some of these men have spent thirty or forty years of their lives engaged in this perpetual task. Fancy being entombed all alone day after day in vaults which are invariably dark and gloomy, and often cold and dank, and being obliged to twist sixty to seventy of these bottles every minute throughout the day of twelve hours. Why the treadmill and the crank with their periodical respites must be pastime compared to this maddeningly monotonous occupation, which combines hard labour, with the wrist at any rate, with next to solitary confinement. One can understand these men becoming gloomy and taciturn, and affirming that they sometimes see devils hovering over the bottle-racks and frantically shaking the bottles beside them, or else grinning at them as they pursue their humdrum task. Still it may be taken for granted that the men who reach this stage are accustomed to drink freely of raw spirits, and merely pay the penalty resulting from over-indulgence.
[Illustration]
In former times the bottles used to be placed with their heads downwards on tables pierced with holes, from which they had to be removed and agitated. In 1818, however, a man named Muller, in the employment of Madame Clicquot, suggested that the bottles should remain in the tables whilst being shaken, and further that the holes should be cut obliquely so that the bottles might recline at varying angles. His suggestions were privately adopted by Madame Clicquot, but eventually the improved plan got wind, and the system now prevails throughout the Champagne. When the bottles have gone through their regular course of shaking they are examined before a lighted candle to ascertain whether the deposit has fallen and the wine become perfectly clear. Sometimes it happens that, twist these men never so wisely, the deposit refuses to stir, and takes the shape of a bunch of thread technically called a "claw," or an adherent mass styled a "mask." When this is the case an attempt is made to start it by tapping the part to which it adheres with a piece of iron, the result being frequently the sudden explosion of the bottle. As a precaution, therefore, the workman protects his face with a wire-mask or gigantic wire spectacles, which give to him a ghoul-like aspect.

The cellars of the champagne manufacturers are very varied in character. The wine that has been grown on the chalky hills undergoes development in vaults burrowed out of the calcareous strata underlying the entire district. In excavating these cellars the sides and roofs are frequently worked smooth and regular as finished masonry. The larger ones are composed of a number of spacious and lofty galleries, sometimes parallel with each other, but often ramifying in various directions, and evidently constructed on no definite plan. They are of one, two, and, in rare instances, of three stories, and now and then consist of a series of parallel galleries communicating with each other, lined with masonry, and with their stone walls and vaulted roofs resembling the crypt of some conventual building. Others of ancient date are less regular in their form, being merely so many narrow low winding corridors, varied, perhaps, by recesses hewn roughly out of the chalk, and resembling the brigands' cave of the melodrama, while a certain number of the larger cellars at Reims are simply abandoned quarries, the broad and lofty arches of which are suggestive of the nave and aisles of some Gothic church. In these varied vaults, lighted by solitary lamps in front of metal reflectors, or by the flickering tallow candles which we carry in our hands, we pass rows of casks filled with last year's vintage or reserved wine of former years, and piles after piles of bottles of _vin brut_ in seemingly endless sequence--squares, so to speak, of raw champagne recruits awaiting their turn to be thoroughly drilled and disciplined. These are varied by bottles reposing necks downwards in racks at different degrees of inclination according to the progress their education has attained. Reports caused by exploding bottles now and then assail the ear, and as the echo dies away it becomes mingled with the rush of the escaping wine, cascading down the pile and finding its way across the sloping sides of the floor to the narrow gutter in the centre. The dampness of the floor and the shattered fragments of glass strewn about show the frequency of this kind of accident. The spilt wine, which flows along the gutter into reservoirs, is usually thrown away, though there is a story current to the effect that the head of one Epernay firm cooks nearly everything consumed in his house in the fluid thus let loose in his cellars.
In these subterranean galleries we frequently come upon parties of workmen engaged in transforming the perfected _vin brut_ into champagne. Viewed at a distance while occupied in their monotonous task, they present in the semi-obscurity a series of picturesque Rembrandt-like studies. One of the end figures in each group is engaged in the important process of _dégorgement_, which is performed when the deposit, of which we have already spoken, has satisfactorily settled in the neck of the bottle. Baskets full of bottles with their necks downwards are placed beside the operator, who stands before an apparatus resembling a cask divided vertically down the middle. This nimble-figured manipulator seizes a bottle, holds it for a moment before the light to test the clearness of the wine and the subsidence of the deposit; brings it, still neck downwards, over a small tub at the bottom of the apparatus already mentioned; and with a jerk of the steel hook which he holds in his right hand loosens the _agrafe_ securing the cork, Bang goes the latter, and with it flies out the sediment and a small glassful or so of wine, further flow being checked by the workman's finger, which also serves to remove any sediment yet remaining in the bottle's neck. Like many other clever tricks, this looks very easy when adroitly performed, though a novice would probably empty the bottle by the time he had discovered that the cork was out. Occasionally a bottle bursts in the _dégorgeur's_ hand, and his face is sometimes scarred from such explosions. The sediment removed, he slips a temporary cork into the bottle, and the wine is ready for the important operation of the _dosage_, upon the nature and amount of which the character of the perfected wine, whether it be dry or sweet, light or strong, very much depends.
Different manufacturers have different recipes, more or less complex in character, and varying with the quality of the wine and the country for which it is intended; but the genuine liqueur consists of nothing but old wine of the best quality, to which a certain amount of sugar-candy and perhaps a dash of the finest cognac spirit has been added. The saccharine addition varies according to the market for which the wine is destined: thus the high-class English buyer demands a dry champagne, the Russian a wine sweet and strong as "ladies' grog," and the Frenchman and German a sweet light wine. To the extra-dry champagnes a modicum dose is added, while the so-called "_brut_" wines receive no more than from one to three per cent. of liqueur.
