The picking ordinarily commences with daylight, and the vintagers assert that the grapes gathered at sunrise always produce the lightest and most limpid wine. Moreover by plucking the grapes when the early morning sun is upon them they are believed to yield a fourth more juice. Later on in the day, too, spite of all precautions, it is impossible to prevent some of the detached grapes from partially fermenting, which frequently suffices to give a slight excess of colour to the must, a thing especially to be avoided--no matter how rich and ripe the fruit may be--in a high-class champagne. When the grapes have to be transported in open baskets for some distance to the press-house, jolting along the road either in carts or on the backs of mules, and exposed to the torrid rays of a bright autumnal sun, the juice expressed from the fruit, however gently the latter may be squeezed, is occasionally of a positive purple tinge, and consequently useless for conversion into champagne. On the right of the road leading from Dizy to Ay we pass a vineyard called Le Léon, which tradition asserts to be the one whence Pope Leo the Magnificent, the patron of Michael Angelo, Raffaelle, and Da Vinci, drew his supply of Ay wine. The village of Ay lies right before us at the foot of the vine-clad slopes, with the tapering spire of its ancient church rising above the neighbouring hills and cutting sharply against the bright blue sky. The vineyards, which spread themselves over a calcareous declivity, have mostly a full southern aspect, and the predominating vines are those known as golden plants, the fruit of which is of a deep purple colour. After these comes the _plant vert doré_, and then a moderate proportion of the _plant gris_, the latter a white variety, as its name implies. A limited quantity of wine from white grapes is likewise made in the neighbouring vineyards of Dizy.
