Manual of American Grape-Growing Part 22

Table-grapes from both eastern and western grape regions are now almost entirely s.h.i.+pped in carload lots. Since few grape-growers are prepared to load a car quickly with grapes, some kind of cooperation is required, or the crop must be handled by large buyers. Cooperative methods are becoming more and more popular, although a large part of the grape crop, both East and West, is now handled by buyers.

There are several important advantages in selling through a cooperative organization. Thus, in selling cooperatively, the grapes are graded and packed in accordance with one standard; more favorable transportation rates can be secured by a cooperative a.s.sociation; and, most important of all, the output can be distributed to the grape markets of the country without the disastrous compet.i.tion that attends individual marketing. In some of these organizations, also, supplies needed by the grape-grower in producing a crop are purchased more economically than by individuals; in particular, grape packages can be purchased better by an organization than by an individual.

As the grape industry and compet.i.tion grow in the different regions of the country, the necessity of forming marketing organizations becomes greater. Such organizations must be founded on the principles which many experiments have shown best govern fruit-marketing a.s.sociations.

It is not possible to discuss these principles at length, but the following fundamentals will suffice:

An ideal cooperative a.s.sociation is one in which there are no profits nor dividends. Every member of the whole organized a.s.sociation is a producer. All of the product grown by a member is sold through the a.s.sociation. The a.s.sociation is democratic, all members having an equal voice in its management and all sharing alike in its successes and failures. When profits arise of necessity, they are distributed to the members of the a.s.sociation in proportion to the amount of business each has done. The work of the organization is conducted at as near cost as possible and profits are declared only after expenses, depreciation, interest on capital for future operations are deducted.

Thus it is seen that the plan of the organization is to give each member as nearly as possible the exact price his fruit has brought in the markets.

VINEYARD RETURNS

Grape-growing as a business is a comparatively new industry in America. It is true that the first attempts at growing this fruit were made to found an industry, but these were complete and dismal failures, and the start in growing grapes in America eventually came as a pleasing hobby. In evolving from a hobby into vineyard culture on a large scale, the business side of the industry long lagged. At present, with increasing compet.i.tion, manifold uncertainties in vineyard conditions, and much unbusinesslike administration, interest in cultural operations, with which pioneers in the industry were chiefly concerned, is eclipsed by the conception that grape-growing is a highly developed commercial enterprise requiring for success careful business management.

Unfortunately there is nowhere a substantial body of figures from which growers can obtain a fair conception of what the outgo and income of average vineyards in grape regions are. The value of such data to investors or to those making an effort to keep track of the finances of their business is obvious, and an attempt is made here to put the reader in possession of figures that ought to be helpful. The data given, although scant and fragmentary, show fairly accurately the cost of producing grapes, selling prices and profits in the culture of this fruit in one of the great grape regions.

The New York Agricultural Experiment Station is carrying on experiments to determine the outgo and income from vineyards in the Chautauqua grape-belt. The work is not yet finished, nor could the findings be published in detail before being sent out by the Station, but F. E. Gladwin, in charge of the work, has consented to set down summaries of costs and returns taken from vineyards at Fredonia, which will serve as a guide to planters of grapes in this region at least:

CHAPTER XIV

GRAPE PRODUCTS

Over-production, with the attendant losses caused by glutted markets, is a factor which, like frosts and freezes, is ever in the mind of the grape-grower. No season pa.s.ses but that some of the grape regions of the country suffer from over-production. Not uncommonly the grape industry in a region is better off in a season when the crop is small and prices high, than when the crop is large and prices low. In every part of the country where grapes are grown, over-production has been a great deterrent to viticulture; this, in spite of the fact that grape-growers have availed themselves of the opportunity to manufacture products from this fruit. Thus, wine and raisins are made from the grape in California, and a large part of the harvest in the East goes into wine, champagne and grape-juice. But the growth of prohibition now threatens the wine and champagne industries of the country, in fact may be said to have driven them to the wall, making the need of new outlets in manufactured products a greater necessity.

Under these conditions, grape-growers must seek in every way to enlarge the sale of the crop to manufacturers with the hope that thus, together with more perfect distribution of his commodities, the inroads made by prohibition on the industry may be offset and the over-production of table-grapes be better prevented. With this brief emphasis on the importance of manufactured products of the grape, we approach the discussion of the several possible outlets to over-production in this fruit.

WINE

The manufacture and use of wine in America, as has been intimated, is likely to cease through prohibition. Therefore, whatever may be said of this product of the grape is of less and less interest to grape-growers. However, a few years of grace probably remain for the making of wines in America, and since wine-making yet offers the greatest outlet for the grape crop, next to table-grapes, wine must be considered as a factor in the grape industry.

Since the demand and price for grapes depend very largely on the kind of wine to be made, it is necessary to characterize the wines made in America. Wine, it should be said, is the product of alcoholic fermentation of the grape. Alcoholic fermentations made from other fruits are not, strictly speaking, wines. Natural wines are divided into three broad groups; dry, sweet and sparkling wines. Dry wines are those in which sugar has been eliminated by fermentation; sweet wines those in which sufficient sugar remains to give a sweet taste; and sparkling wines are those which contain sufficient carbonic acid gas to give a pressure of several atmospheres in the bottle. The carbonic acid gas is produced in sparkling wines by fermentation in the bottle of a dry wine.

The color in these three cla.s.ses of wine may be red or white, depending on whether or not the color is extracted from the skins in the process of fermentation. To make red wine, of course, the grapes to be fermented must have red coloring matter in skin or juice or both. Each of these groups of wine includes a very large number of kinds distinguished by the name of the region, the locality or the name of the vineyard in which a wine is made. Wines are still further distinguished according to the year of the vintage.

_Wine-making._

There are four distinct stages in the making of wine after the grapes are grown. The first is the harvesting of the grapes when they have reached the proper stage of maturity, which is known as "wine-making ripeness." This stage of ripeness is determined by means of a must-scale or saccharometer. The wine-maker squeezes the juice from a number of bunches of grapes into a receptacle into which he drops the must-scale, whereupon the sugar-content of the juice is indicated on the scale, determining whether the proper stage of ripeness has been reached. Suitable varieties of grapes having been grown, it is necessary that they be permitted to hang on the vine until the proper degree of ripeness is developed, after which they are delivered at the winery as free as possible from injury or decay.

The second stage is the preparation of the grapes for fermentation.

The grapes are weighed on arriving at the winery and are then conveyed either by hand or more often by a mechanical conveyor to the hopper or crusher. The ancient method of crus.h.i.+ng, which still prevails in some parts of Europe, was to tramp the grapes with bare feet or wooden shoes. Tramping has been superseded by mechanical crushers which break the skin but do not crush the seeds. The best mechanical crushers consist of two-grooved revolving cylinders. As the grapes pa.s.s through the crusher, they fall into the stemmer, a machine which tears off the stems, discharging them at one end, while the seeds, skins, pulp and juice pa.s.s through the bottom to the presses usually on the floor below. There are several types of wine-presses, all of which, however, are modifications of screw, hydraulic or knuckle-joint power. In large wineries, the hydraulic press has almost driven out the other two forms of power and when great quant.i.ties of grapes must be handled a number of hydraulic presses are usually in operation. The grape pomace is built up into a "cheese" by the use of cloths and racks variously arranged. The "cheese" is then put under heavy pressure from which the juice or "must" is quickly extracted.

The third stage is fermentation. The "must" is carried from the press into open tanks or vats which hold from 500 to 5000 gallons or even more. The yeast cells which cause fermentation may be introduced naturally on the skins of the grapes; or in many modern wineries the "must" is sterilized to rid it of undesirable micro-organisms and a "starter" of "wine-yeast" is added to start the fermentation. Yeast organisms attack the sugar and must, breaking it up into alcohol and carbonic acid gas, the latter pa.s.sing off as it is formed. When active fermentation ceases, the new wine is drawn from the pomace and is put into closed casks or tanks where it undergoes a secondary fermentation, much sediment settling at the bottom of the cask. To rid the new wine of this sediment, it must be drawn off into clean casks, an operation called "racking." The first racking usually takes place within a month or six weeks. A second racking is necessary at the end of the winter and a third is desirable in the summer or fall.

The fourth stage is the aging of the wine. Before aging begins, however, the wine usually must be rendered perfectly clear and bright by "fining." The materials used in fining are isingla.s.s, white of egg or gelatine. These, introduced into the wine, cause undissolved matters to precipitate. The wine is now ready for bottling or consumption. Most wines acquire a more desirable flavor through "aging," a slow oxidation in the bottles.

_Champagne._

When champagne wines have gone through their first fermentation, they are racked off into casks to age until their quality can be ascertained, after which a blend of several different wines is made.

This blend is called the "cuvee." The cuvee is bottled and a second fermentation starts. The bottles are now put in cool cellars, corded in horizontal layers with thin strips of wood between each layer of bottles. The champagne in this stage is said to be in "tirage." The carbonic acid gas generated at this second fermentation is confined in the bottles and absorbed by the wine. When the bottle is uncorked, the gas, seeking to escape, produces the sparkling effect desirable in sparkling wines. After the wine has been in tirage for one or two years, the bottles are placed in A-shaped racks, the neck of the bottle pointing downward so that the sediment formed during fermentation drops to the cork. To further the settling of the sediment, workmen turn or shake each bottle daily for a period of one to three months. The bottles are then taken to the finis.h.i.+ng room, cork down and the wine is "disgorged." Disgorging is accomplished by freezing a small quant.i.ty of wine in the neck of the bottle containing the sediment, after which the cork is removed and with it the frozen sediment. The bottle is refilled, recorked, wired, capped, and the champagne is ready for s.h.i.+pment.

_The vintage._

The wine-making season the world over is known as the "vintage." The time at which the vintage begins depends, of course, on the region, the variety of grapes, the growing season and the location of the vineyard. Its duration, also, depends on these same factors. The season is usually lengthened by the fact that wine-makers require for their purposes a number of varieties of grapes which ripen at different times. Before or during the vintage, representatives of wine cellars usually make contracts for the number of tons of grapes required at a certain price a ton.

The notion prevails that grapes for wine and grape-juice need not be first-cla.s.s. This is far from the truth. To make good wine the grapes must be carefully harvested, transported with as little injury as possible and must be protected from dirt, mold and fermentation before reaching the winery. European vintagers maintain that grapes picked at sunrise produce the lightest and most limped wines and yield more juice. They say, also, that the grapes should not be gathered in the heat of the day because fermentation sets in at once. These niceties are not observed in America.

_Prices paid for wine grapes._

Supply and demand regulate the price paid for wine grapes. There is always demand for good wine grapes, although a poor product often goes begging for market. In the East, the highest prices are paid for the grapes used in making champagne. The champagne region of the East is confined to a few localities along Lake Erie and to western New York about Keuka Lake, where the industry is most largely developed. The varieties used in champagne-making in the East are Delaware, Catawba, Elvira, Dutchess, Iona, Diamond and a few other sorts. Prices differ with the many conditions affecting the grape and champagne industries, perhaps the average price for Catawba, the grape chiefly used in making champagne in this region, being from $40 to $50 a ton. Choicer grapes, as Delaware, Iona and Dutchess, often sell from $75 to $100 a ton. Concords are sometimes utilized in making dry wines in the eastern states, $30 or $40 a ton being the average price. Ives and Norton are much used for red wines and sell for top prices.

Wine-makers in the East are at a disadvantage in producing wines other than champagne, since the price paid on the Pacific slope for wine grapes is much lower; Grapes for sweet wine in California often sell as low as $6 or $7 a ton, the average price being $10 or $12. Grapes for dry wines, such as Zinfandel and Burger, bring on the Pacific coast from $10 to $12 a ton. Choice varieties of grapes in this region, such as Cabernet, Sauvignon, Pet.i.te Sirah and Riesling, bring from $22 to $24. The eastern wine-makers, however, have the advantage of being close to the largest and best markets in the country. Wines made in the East are very different from those made in California and supply a different market.

A few years ago most of the Muscadine grapes grown in the South were used for wine-making. From these grapes wine has been made since colonial times, and for a century there have been some large vineyards of Muscadine grapes in the South from which wine was made in a commercial way. Since Muscadine grapes do not sell well in the markets in compet.i.tion with the grapes of the North or the Pacific slope, the Muscadine grape industry has been dependent on the wine industry of the section in which the fruit is produced. The growth of prohibition in the South, however, has driven the wine industry to the North and West and there is now little wine manufactured from Muscadine grapes in the South, although some grapes are s.h.i.+pped North for wine-making.

The wine made from these grapes is very distinct in flavor and on that account a special trade has been developed for it. It is possible that this special trade will keep up the demand for Muscadine wine so that some part of the crop may be s.h.i.+pped to wine-making states to supply this demand.

GRAPE-JUICE

When properly made, grape-juice is the undiluted, unsweetened, unfermented juice of the grape and contains no preservatives, fermentation being prevented by sterilization with heat. The product is as ancient as wine, and, therefore, as the cultivation of the vine, for all wine-making peoples have used new wine or grape-juice as a beverage. For centuries physicians in wine-making countries have prescribed grape-juice as it comes from the wine-press for certain maladies, the treatment const.i.tuting an essential part of the grape-cures of European countries. The process of making an unfermented grape-juice that will keep from season to season as an article of commerce is, however, a modern invention, and is the outcome of the discoveries of the last half century regarding the control of the agents of fermentation.
