—The older vineyards had their vines set seven feet by seven feet, but of late the vines are planted generally eight feet by four feet, thus much closer than by us in California.
Pruning.
—The pruning of the vineyard is performed very much as in California. Formerly the soil had to be removed from the vines before they could be pruned; now this is not necessary except while the vines are very young. The various branches are pruned back to a few inches, with two eyes each, while the heads are elevated only a few inches above the ground.
Manuring and Fertilizing.
—The Malaga vineyardist fully understands the value of manuring his vineyards, and uses for this purpose not only all fertilizers available at home, but also imports directly from distant countries. The most valued fertilizers are the Mexican and Chilean guanos or phosphates. The Mexican phosphate costs in Malaga sixty-five dollars per ton; still it is used by all the principal vineyardists, who know the value of fertilizers. In fact, concentrated fertilizers are a necessity to the Malaga vineyards; without them they could not be cropped. Even the most virgin soil is exhausted in ten years’ time by constant croppings of raisin grapes; no paying crops could be expected if fertilizers were not used yearly. This fertilizing of the soil is, however, of recent origin, and fifty years ago was almost unknown.
When home manures are used, it is placed in holes dug round the roots of the vines, which, after exposure to the air for several months, are again filled up at the advent of spring, generally in March, before the vines start to bud.
Drying-floors, or Sequeros.
—The raisins, when picked, are dried on so-called sequeros, or drying-floors, characteristic of the Malaga district. These floors are of different sizes and lengths in different vineyards, but everywhere constructed on the same general principles. Where an incline or a hill is found, the floor may simply be built on the slope, with no artificial elevation; but, where the ground is level, the structure of the sequero is different. The floor must always face the south, and the back is raised to give the floor the proper slope. The sequero thus consists of four walls, the front one of which is only a foot high, and the back wall from six to eight feet high. The side walls slope between these, generally with an angle of forty-five degrees. In length, these floors vary from forty to fifty feet, according to the different ideas of the vineyardists. The whole interior is filled with black gravel, and is tamped hard. These sequeros are divided in beds, fourteen feet or so wide, by tiles that are sunk, thus forming walks of several feet in width, and which also serve for leading off the rainwater. Around every little bed of this kind are small upright tiles to prevent the rainwater entering from the walks. Finally, in the center of the bed, is a long row of upright tiles, high enough to support either boards, mats, or more generally canvas, in order that they may shed the rain into the tile walks. The value of such floors is evident. Being covered with canvas, etc., every night, the heat is preserved, and every morning, when the sun rises, the grapes are yet warm. The drying on such beds has never, in fact, been interrupted. The drying-floors are also useful in case of too hot weather, when the grapes can be properly sheltered with canvas and prevented from being cooked; when finally dried, the covering, again, will serve to keep the moisture from too quickly evaporating.
Drying and Curing.
—When the grapes are picked, the best vineyardists separate the bunches immediately in three different grades. Each grade is placed by itself on the gravelly drying-ground, and remains there to dry. When half dried, they are taken bunch by bunch by a workman, who picks out bad or overdried berries and rubbish, and in putting the bunch back turns it over. In ten days the grapes are generally dried, provided the weather has been favorable. Every night the canvas covering is slid down over the sequero, and the grapes protected from dew and cold, or rain. The drying is sometimes greatly hastened by the Terral or hot winds blowing from the plains of La Mancha, a wind very similar in its effect to the desert wind of Riverside and Santa Ana, in California.
