—The Muscat cuttings are planted generally in February. The best cuttings are considered to be those taken from vines at least six years old. The cuttings are set at various distances according to the richness of the soil. The richer the soil the less room is given the vines. Thus the vines are set either five by eleven feet or five by twelve feet, or, in other words, they are set in rows eleven or twelve feet apart, with the vines five feet apart in the row. The depth of the cutting is regulated by the moisture of the surface soil, but averages eighteen inches. The vines begin to bud in the middle of March, and are from the start subject to great care and constant cultivation. The first operation after the cutting is planted is to cut off the top bud as soon as the vine starts to grow, leaving the two shoots only from the two lower buds. No more shoots are allowed to grow the first year. Next winter the smaller of these two branches is cut off completely and the remaining branch is pruned back to two eyes. In the second year the young shoots from the vine are allowed to grow to ten inches or so long, when all are cut away except two of the strongest. Next winter again these are pruned so to leave only two eyes on each, or four buds on the whole vine. In the succeeding years the branches are gradually increased in number, but always pruned back to two eyes. After the vine is five years old, it is seldom increased as to branches; it is then always pruned back to the same number of spurs. It can be said that the Denia growers pay less attention to the quality of the raisins, and prune more to attain quantity. They leave more spurs on their vines than do those in Malaga, and in this respect resemble many of our own California growers, who frequently leave from twelve to fifteen spurs on a vine. The vines in Denia are also raised higher above the ground than in Malaga, very much as we have been in the habit of pruning our own vines. At the age of three years the vines come into bearing; but no fine raisins are made until the vines are five or six years old.
Dipping and Scalding.
—The dipping process is one of the greatest importance, and gives the peculiar characteristics to the Valencia or Denia raisins. As a similar process will sometime or other be more generally used in California, a more detailed description may prove interesting to California growers. We can probably not do better than to imitate them, although in mechanical appliances we will readily improve upon their methods. The dipping is always done at the drying ground or secadero. The larger part of the dipping apparatus, or the kettles, are placed under the ground so as to save heat and fuel. A trench eight or nine feet in length is dug to the depth of three or four feet. At one end is built a chimney protruding three or four feet above the level of the ground. In the other end of the trench is built a brick wall with an opening for feeding the fire. Some trenches are lined inside with bricks, making them more permanent and solid. On the top of this flue, and on a level with the ground, are built the kettles or boilers, containing not less than twenty gallons each. The boiler nearest the fire entrance is destined to contain a solution of lye or ashes, the one next to the chimney being for boiling water only.
The lye is made from the ashes of burnt vine cuttings, together with lime and sometimes some salt, by men who have acquired the art from years of experience, and who know by the appearance of the scalded grapes whether the solution is too strong or too weak. If too weak, the skins of the grapes will be insufficiently cut, which will delay the drying of the grapes, and cause them to rot if the weather is damp and foggy. If, again, the lye solution is too strong, the skin will be destroyed and the berries seriously injured.
The grapes to be dipped should be perfectly ripe. If dipped before, they will become inferior both as to color and taste. The perfect ripeness is a most important point. The grapes are picked in baskets of about ten pounds each, and carried to the scalder. The man nearest him on the right fills a perforated ladle with about twenty pounds of the grapes. The ladle is made either of wire netting or of tin or zinc, with large perforated holes about three-eighths of an inch wide. There is a scalder at each boiler. The first scalder dips the grapes in the scalding water for a second, and immediately hands them to the second scalder, who dips the same ladle in the boiling lye solution for not over two seconds. The grapes are then carefully turned out on trays to dry.
The dipping first in scalding water is of the greatest importance, both in washing off the dust of the grapes and in preparing them to receive the alkali wash with more effect. Since the hot-water process was introduced, the Valencia raisins have materially improved in quality. The grapes are never rinsed in cold water after being dipped, and it is more than likely that the lye prevents molding, as, according to A. B. Butler, dipped raisins are sometimes exposed to the rain for three weeks without being totally ruined. In California, our dipped and washed raisins spoil quickly if exposed to rain. The object of dipping is, of course, to slightly crack the skins so as to allow the water to readily evaporate. Dipped raisins dry sometimes in five days, while undipped raisins would require as many weeks. Efforts to produce sun-dried raisins without dipping them have repeatedly been made in Denia; but they are invariably spoiled by the rain, and lately two firms were ruined in their attempts to dispense with the dipping process.
Drying and Curing.
—After the grapes have been properly dipped, the drying proceeds very quickly. The grapes are immediately spread on cane trays or cañezos, about six feet long by three or four feet wide. These cane trays are made of the common Italian reed or Arundo donax, which grows everywhere, even in California, and is here incorrectly known as bamboo. The trays are made either of split or of entire canes tied strongly together. These trays are placed flat on the ground, only leaving enough space around each one to allow the workmen free access to the tray on all sides. After having been exposed to the sun for three days, the grapes are turned, in order to dry evenly on both sides. On the fifth day, the raisins are turned again, and, if the weather has been favorable, many of the raisins are then ready to pack. A day or two after this, all the raisins are ready, and are collected and housed. If, again, the weather has been unfavorable, the drying is very much delayed. At the approach of rain, the mats or trays are taken up and piled on the top of each other, under sheds previously made. Every drying ground has stationary appliances for this purpose. These simply consist of poles stuck in the ground, and extending five or six feet above the same. Other cross-rafters or scantlings are nailed between the poles, thus forming rows of roofless sheds eight or nine feet wide, of greater or shorter length. Painted canvas, or simply mats or empty reed trays, are used as covers, under which the raisin trays are piled. Under and between each tray are placed five little cubes of wood, for the purpose of lifting the tray and preventing it from pressing too heavily on the grapes underneath.
Packing and Disposing of the Crop.
—When at last the raisins are dried, they are either stored by the producer, or, as is more generally the case, are taken to the merchant or packer who has supplied the grower’s wants during the year in anticipation of the coming crop. There are thus a number of special packers in Denia, who own large and splendid packing-houses in which the crop is yearly handled. The grower never packs himself, the enhanced value of the raisins not being sufficient to warrant the trouble. One of the best and by far the largest packing-houses in Denia is owned by J. D. Arquimbau. A more perfectly equipped establishment is not found anywhere else.
