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.
