Ever busy among his vats and presses, barrels and bottles, Perignon found out a method of clearing wine, so as to preserve it perfectly limpid and free from all deposit, without being obliged, like all who sought to rival him in its production, to _dépoter_ the bottles--that is, to decant their contents into fresh ones.[103] This secret, which helped to maintain the high reputation of the wine of Hautvillers when the manufacture of sparkling Champagne had extended throughout the district, he guarded even better than he was able to guard the apple of his eye. At his death, in 1715, he revealed it only to his successor, Frère Philippe, who, after holding sway over vat and vineyard for fifty years, died in 1765, imparting it with his latest breath to Frère André Lemaire. Revoked perforce from his functions by the French Revolution, he in turn, before his death about 1795, communicated it to Dom Grossart, who exults over the fact that whilst the greatest Champagne merchants were obliged to _dépoter_, the monks of Hautvillers had never done so.[104] Dom Grossart, who had counted the Moëts amongst his customers, died in his turn without making any sign, so that the secret of Perignon perished with him. Prior to that event, however, the present system of _dégorgeage_ was discovered, and eventually _dépotage_ was no longer practised.[105] The material result of Dom Perignon's labours was such that one of the presses of the abbey bore this inscription: 'M. de Fourville, abbot of this abbey, had me constructed in the year 1694, and that same year sold his wine at a thousand livres the queue.'[106] Their moral effect was so complete that his name became identified with the wine of the abbey. People asked for the wine of Perignon, till they forgot that he was a man and not a vineyard,[107] and within a year of his death his name figures amongst a list of the wine-producing slopes of the Champagne.[108] His reputation has outlasted the walls within which he carried on his labours, and his merits are thus recorded, in conventual Latin of the period, on a black-marble slab still to be seen within the altar-steps of the abbey-church of Hautvillers.[109] [Illustration: D .
