LAYER RAISINS.
Sweating or Equalizing.
—This is a process by which the overdried raisins are made to attract sufficient moisture from the underdried raisins in the same box or bunch, and whereby the overdried raisins are made moister, while the underdried ones become drier. Equalizing also moistens the stems sufficiently to prevent them from breaking when being handled. In our California climate, where the air is so dry, this equalizing process is an absolute necessity, and no first-class raisin pack can be produced without the raisins having first been equalized. The word “equalizing” is to be preferred to “sweating,” as the latter word may be misunderstood as meaning that a certain amount of heat is developed by storing the raisins. Heat is indeed necessary, but it should come from the outside air, not from the inside or from the raisins. If from the latter the raisins will be in a fair way to become spoiled. In the foregoing I have described the construction and workings of the sweathouse. It may be suggested that, if there is no sweathouse on the vineyard, a large sail or canvas may be used as a substitute. The latter is simply thrown over the boxes where they are piled out-of-doors, and answers to some degree in keeping the raisins moist. But as this is only a substitute, I shall not dwell longer on its usefulness. It may, however, be said in favor of this appliance, that it is used by one of our largest packers, and by him considered as of equal value if not superior even to a regularly constructed equalizing house.
The raisins which are to be sweated are only the clusters or layers, and not the loose, which as we have seen should at once be taken from the field to the stemmer, while the stems are yet crisp and dry. It is therefore of importance that the bunches or layers should be separated from the loose already in the field, or, which is much preferable, before they are dried, at the time when they are picked from the vines. If the latter is done properly, there will be only a small quantity of loose which will go in the sweating-house with the layers. The layers should at any rate be placed at once in sweatboxes when taken from the trays, and between every two layers of bunches there should be a stout sheet of manilla paper, in order that the bunches may not become mixed. When taken to the sweathouse the boxes should be so placed that air can enter every one. It will not do to place one box on top of another so as to cover up the top entirely, as the raisins are then apt to ferment in a very short time, and, before the raisin-packer is aware, whole piles may be absolutely spoiled. It is not necessary to place the boxes crosswise, as it is enough to allow the short side of each box to overlap the underlying box a little; sufficient air will then enter. In very dry weather the floor of the sweathouse may be sprinkled with water, but this is generally not needed, as the underdried raisins will give out moisture enough to soften those that are too dry, as well as the stems. Every day the sweathouse should be aired, and it is a mistake to believe that all air should be excluded. If air is not daily admitted, the raisins will mold and spoil, and it is even advisable to keep a circulation of air constantly through the house during the daytime. The attentive packer will soon learn to regulate this, and nothing but actual experience with his particular sweathouse will enable him to decide how much air should be let in and to what extent the doors should be closed.
At the end of from ten days to three weeks, the equalizing process should be over, and the layers ready for further packing. When the boxes are removed, it will be found that the majority of those raisins which had been too moist or underdried have dried sufficiently, while on the contrary the overdried raisins, as well as the formerly brittle stems, will have acquired sufficient moisture to enable the packer to manipulate them without risk of breaking the bunches. The raisins should be pliable, and stand moderate pressure without cracking or breaking. But while equalizing is an important operation, and one which we cannot dispense with, it is always to the grower’s interest to so dry his raisins previously that they will require as little equalizing as possible, as even the most carefully sweated raisins which have once been overdried will never afterwards equal those which were at once properly dried in the field. The overdried raisins will always have a tougher skin and be inferior in color; but on the other hand they will keep better than raisins which have been dried less.
Grading and Weighing.
—The next step after the raisins have been equalized is to remove them to the grading tables. This should not be done by dumping the contents of a sweatbox on the table, as in this way but very few of the real choice bunches are saved for the packer. If, however, the raisins have been placed carelessly in the boxes, without sufficient or perhaps without any manilla papers between the layers, the only way is to dump out the contents. By first placing the sweatbox on the long side, and then turning it over, the raisins are but slightly disturbed. But to get these out afterwards from the chunk is the great difficulty, and many bunches must necessarily be broken. If, again, the raisins have been carefully handled and consigned to the sweatboxes, with four papers in every box, not counting in the top cover, the care and handling of the sweatboxes will be much simplified. The sweatbox is then placed alongside of the grading table, and each layer with its paper is lifted out carefully, and placed on the table. The assorting is now to begin. The bunches are taken up one by one, all inferior berries are clipped out, all soft ones are separated and placed in a box by themselves to be further dried. As each bunch is examined and cleaned, it is put in one of the weighing trays resting on small scales at either end of the table, and, when the scales indicate that five pounds of raisins are in the tray, the latter is removed to the packing table.
In the meantime all loose or inferior bunches are raked down through the openings in the grading tables and received in sweatboxes below, to be either further dried or to be stemmed and graded at once. In packing several grades of layer raisins, the grading of the bunches should be made at this table. No great choice in selecting the bunches should be left to the packer, as his time should alone be occupied with the packing of his box. The best way is to have differently colored scales for number one and number two layers, and when taking them out of the sweatbox assort them at once by placing them in different trays. The graders can never be too careful. No moist raisins, no small ones, no red and poor raisins, should ever be allowed among a better quality. They will lower the grade of the whole box, while the good quality of high-grade raisins will not raise the grade of a generally poor box. Thus, while the many good raisins in a poor box are not paid for according to their value, the few poor raisins which will be accidentally or carelessly smuggled in a good box will lower the value of the whole. Few packers will sufficiently understand this, which is really the principle of all good packing, and which should be scrupulously adhered to. Even inferior size berries, if otherwise ever so good, should be carefully clipped from the large-berried bunches. It is astonishing how quickly the buyer will notice a few small berries, and how readily he will ignore the value of the largest raisins in the box.
Packing Layers, Top-up Method.
—As with packing the loose raisins, there are two methods, the top up and the top down. The top-up method can be as little recommended in this case as in the former, but as it is used by many of the packers I will here describe it: The trays containing the five-pound layers are placed in front of the packer on the packing table, so as to be within easy reach of the packer. The trays or frames with the sliding bottom are now used. The first move is to place one of the inner paper wrappers in the tray, and next the layers are placed in the frame as carefully as possible. There are two ways in vogue in which this is done. One of them is to crowd the raisins to one side,—“bunch” them, so to say, beginning at one end of the tray and gradually working towards the other end. This is the wrong way, which I am sorry to say is used by very many packers, who desire speed above everything, thus sacrificing care and quality and even appearance. Raisins packed this way point their ends upwards in a slanting way, which not only detracts from their appearance, but causes them to get entangled in each other. Such bunches when pressed will generally break, and, when lifted out of the box afterwards, will be very different from what they were when they were placed there in the first instance. The raisins, whatever method is used, should always be placed flat on the bottom of the tray. Care should be taken to arrange them so that they will fit, and only very few broken bunches should be allowed to fill unoccupied corners or spaces in the box. It is better even to leave such spaces empty than to tear up good bunches in order to get the small quantities needed, or in using inferior berries to fill up the holes.

When at last the tray is full, and all the five pounds of raisins from the weighing tray are in, the upper surface should be smooth so as to require as little pressure as possible. When full the trays are taken to the press and stored on a side table until actually used. The presses are generally arranged for four trays. These are now placed under the press, a follower is placed on the top of every tray, and only sufficient pressure applied. Frequently too much pressure is used, and the raisins are flattened out to their greatest possible extent, many even crushed and so broken that the juice runs out. All such crushed raisins will sugar in a few months, and the whole box containing them will spoil and deteriorate in value. If, again, the raisins have been properly pressed, they will keep for months or even years. After the trays have been sufficiently pressed, which generally is accomplished in one minute’s time, the pressure is released, the follower removed, the folders turned over the raisins, and the trays removed to the boxing table, on which they may be allowed to accumulate until the boxer is ready to fill his boxes. On this table the final packing or “making up” of a box is done. It takes four of these five-pound frames to fill one whole box. Each tray is in its turn placed over a box, the sliding bottom is quickly removed, and the five-pound layer drops down in the box undisturbed. Every fourth frame should, in addition to the common paper wrapper, have labels and fancy paper pasted on the folders, or, as is sometimes done, an extra fancy folder or wrapper is placed on the third layer, and on the top or inside of it the fourth layer is dropped. Each layer will thus be found in its own wrapper, but the upper layer will have two, the outside one of which is fancy. Fine layers should have a waxed paper immediately above the raisins, in order that the moisture or sugar from them may not spoil the labels. On the top of the waxed paper the chromo or label is placed. The box is now ready for nailing.
Packing Layers, Top-down Method.
—This method I advocate as the most proper one to use. Thin galvanized-iron trays with a drop bottom are used. On the top of the drop bottom is placed a heavy follower of metal. White’s facing-plate, turned over, can be used to great advantage, even where no facing is required. The choicest bunches are now selected and spread evenly on the bottom of the tray; other bunches are placed on top of them, and so on until the tray is full. Great care must be taken in packing so as to make the bunches fit each other and lie solid; otherwise they are very apt to be disturbed, or they will require too heavy pressure to be kept in place. When the tray is full, it is gently pressed, and the pressure kept up for a few seconds. A loose zinc plate is then placed over the tray, the latter is turned over and placed over the box, in which the necessary wrapping papers have been previously placed, the loose zinc plate is quickly withdrawn, and the contents fall into the box. The heavy follower keeps the top layer steady, and with a little care the raisins are not disturbed.
The top-down method for packing layers has the following advantages over the top-up method. It gives a smooth surface on which to pack the top layer, without necessitating pressure to first create such a surface, the packing being done on a hard plate. The wrappers are not soiled, as they are not first placed in the frames. The packer is enabled to pack and select his choicest bunches for the top layer while he has plenty to select from, and any odd berries and broken or smaller bunches come naturally in the bottom of each layer. In the top-up method all such odds remain for the top, where they must go in, in order to make up the required five pounds.
A raisin-packer averages seventy-five trays of five pounds each per day, for which she is paid two cents each. Some pack more than this; but very excellent packing proceeds slower, and a packer of very choice layers can only pack twenty-five trays of five pounds each per day, for which a correspondingly higher price is paid. In Malaga, a trained and expert packer receives between two and three dollars per day. In California, they do not receive any more. In our raisin district, the girls are rapidly becoming expert packers, and the same ones are reëngaged year after year by the same packing-house.
Filling.
—The filling of the raisins is a trick to make them appear larger than they are. This filling was invented in Spain, and is used there especially on Dehesa boxes and where very expensive packing is required. It is done in the following manner. The raisin is first flattened out as much as possible, then the edges are bent, making the raisins slightly concave. In placing the concave side downwards, a smaller raisin is slipped underneath so as to cause the manipulated raisin to keep its shape. These filled raisins are used for facing only. The Spanish filled raisins have been handled to such an extent that all the bloom is lost, and the raisin looks anything but attractive. The California method of filling is a great improvement on the Spanish way. When the facing-plate is used, the raisin is first placed in a cavity on the plate, then worked out by a pressure with the finger, and when sufficiently concave another raisin is dropped in the hollow and pressed tightly. The faced raisin is thus filled, and when seen from the other side will appear much larger than otherwise. When, again, the top-up method of packing is used, a small block of wood may be employed. This block contains a single cavity of the size, that a raisin when pressed will fill it. The counterpart of this block is furnished with a convex protuberance, and when the two halves are placed together with a raisin between, and pressure is brought to bear, the raisin flattens out and becomes concave just enough to receive the filling.
In this way no handling with the fingers is done, and the raisin keeps its bloom undisturbed. Nothing is more attractive than a raisin with its bloom untouched; similarly the raisin that has lost its bloom always gives the buyer an idea that it has been fingered. Its appetizing quality is gone. Spanish Dehesas are generally both faced and filled. Some objection to this method is that it deceives, but as long as people not only are willing to be deceived but are actually anxious to pay for the deception, there is no reason why the filling should not be used. The deception, besides, is a very innocent one. It has also another excuse: A well faced and filled box is really a work of art; it will help to educate the people up to the appreciation of what fine raisins and fine packing should be. Filling and facing combined are practiced but little in California, and it is doubtful if filled facing will ever grow in much demand here.
Nailing and Trimming.
—The boxes are next moved to the nailing table. Two nails are put in the short sides and two in the long sides of the cover. The boxes when nailed are passed to the trimmer, who with a drawknife trims the edges and cuts off the comers diagonally. The latter prevents the boxes or covers from splitting. The best nails are French wire nails for the sides and ends, one and one-quarter inches long, and for tops and bottoms one inch long.
Labels.
—I cannot finish this part without adding some words about our labels. It is of importance that our labels and colored lithographs should be appropriate. The time has come when our raisins should stand upon their own merits, and should be designated with appropriate names. I should wish to see only California names used, California layers instead of London layers, California scenes instead of foreign scenes, which give no idea of our conditions, and which do not help to advertise our State and its resources. Whatever our labels may represent, they should be distinctly Californian. Another point which is but seldom observed on these labels is the shape and color of our raisin grapes. The latter are often represented on the labels, but their shape is seldom observed. Nowhere have we seen on them a true Gordo Blanco or a true Muscat of Alexandria represented, the grapes there pictured being impossible as raisin grapes, or even well-known wine or table grapes, out of which no raisins could be made. The packer has a right to protest against such misrepresentations of our fair grapes, especially as the lithographer could just as readily and just as cheaply have followed the originals. A beautiful label is well worth its price. As a work of art, it is seldom thrown away, but is carefully kept and made to adorn the walls of many a humble home, in which the name and fame of our State will soon be a household word. Let these labels go out by the million yearly to tell of our climate and of our soil, and of the land where the luscious raisins are produced, with the same care as apples or garden stuff in countries less favored by nature.
