At the vintage, which commences towards the end of October and lasts until the middle of the following month, all the rotten or unripe grapes are carefully set aside and the sound ones only submitted to the action of a screw-press. After the must has flowed for about half-an-hour the grapes are newly collected under the press and the screw again applied. The produce of this double operation is poured into a vat termed a _sapine_, where it remains until bubbles are seen escaping through the _chapeau_ that forms on the surface of the liquid. The must is then drawn off--sometimes after being fined--into casks, which the majority of wine-growers previously impregnate with the fumes of sulphur. When in cask the wine is treated in one of two ways; either the casks are kept constantly filled to the bunghole, causing the foam which rises to the surface during the fermentation to flow over, and thereby leave the wine comparatively clear, or else the casks are not completely filled, in which case the wine requires to be racked several times before it is in a condition for fining. This latter operation is effected about the commencement of February, and a second fining follows if the first one fails to render the wine perfectly clear. At the tirage, which invariably takes place in April, the Jura wines rarely require any addition of sugar to insure an ample effervescence. After bottling they are treated in exactly the same manner as the vintages of the Marne are treated by the great champagne manufacturers. In addition to white sparkling wine a pink variety, with natural effervescent properties, is made by mixing with the savagnin and melon grapes a certain proportion of the poulsard species, from which the best red wines of the Jura are produced. One of the principal sparkling wine establishments at Lons-le-Saulnier is that of M. Auguste Devaux, founded in the year 1860. He manufactures both sweet and dry wines, which are sold largely in France and elsewhere on the Continent, and have lately been introduced into England. Their alcoholic strength is equivalent to from 25° to 26° of proof spirit, being largely above the dry sparkling wines of the Champagne, which the Jura manufacturers regard as a positive advantage rather than an obvious drawback. M. Devaux’s principal brand is the Fleur de l’Etoile, of which, he has white, pink, and amber-coloured varieties, quoted by him at merely three francs the bottle for the grand years. Besides being too spirituous, the sparkling wines of the Jura are deficient in refinement and delicacy. The commoner kinds, indeed, frequently have a pronounced unpleasant flavour, due to the nature of the soil, to careless vinification, or to the inferior quality of liqueur with which the wines have been dosed. Out of some fifty samples of all ages and varieties which in my capacity of juror I tasted at the Paris Exhibition I cannot call to mind one that a real connoisseur of sparkling wines would care to admit to his table.
