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 competition 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 shipped 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 shipped 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 constituting 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.

The manufacture of commercial grape-juice in America, to which country the industry is confined, began as a home practice following the fundamental processes of canning fruit. Toward the close of the last century, several inventive minds discovered methods of making a commercial product and began developing markets for their wares. The beginning of the present century found the new industry in full swing, since which time its growth has been truly marvelous. In 1900 the amount of grape-juice made in the United States was so small as to be negligible in the census report of that year. By 1910, the annual output had reached for the whole country over 1,500,000 gallons and at present writing, 1918, it is well above 3,500,000 gallons per annum. The manufacture of grape-juice is no longer a home industry but a great commercial enterprise. It is an industry closely associated with grape-growing, however, and as such needs further consideration here.

Grape-juice regions.

The manufacture of grape-juice is centered in the Chautauqua grape-belt in New York, Pennsylvania and Ohio. So far, the demand seems to be almost wholly for juices made from native grapes, the juice of European grapes grown on the Pacific slope being so sweet as to be insipid. Possibly 80 per cent of the grape-juice now manufactured in America comes from a single variety, the Concord. There can be no question, however, but that sooner or later grape-juices of distinct qualities will be made from many varieties of grapes, thus giving wider sale and greater variation for the product. A very good sparkling grape-juice is now on the market and its reception seems to promise a great increase in the production of an article that closely simulates champagne in color and sparkling vivacity, but not, of course, in taste, since it contains no alcohol. The grape-juice industry has been started and is in a flourishing condition in several other grape regions than the Chautauqua belt which is now its center. There are factories at Sandusky, Ohio, using grapes grown in the Kelly Island district; in southwestern Michigan there are several factories; and the industry still survives at Vineland, New Jersey, which probably should be called the original home of the manufacture of grape-juice. In the South, some grape-juice is made from Muscadine grapes, but this product seems not as yet to have been well received in the markets.

Commercial methods of making grape-juice.

There is at present a great diversity of methods and of apparatus employed in the grape-juice manufacturing plants throughout the country. Since the industry is in its infancy, and the attempt has been made to hold some of the methods as trade secrets, the diversity of methods and appliances is not to be wondered at. No doubt there will be greater uniformity of method and machinery and, therefore, greater efficiency, as the industry develops.

Husmann[19] gives the following account of the manufacture of grape-juice in the eastern states and in California:

"Sound, ripe, but not over-ripe, grapes are used. These are first crushed or, in case the stems are to be removed, are run through a combined stemmer and crusher. If the machinery is stationed high enough, the crushed fruit can be run through chutes directly into the presses or kettles; otherwise, it must be pumped into them by means of a pomace or must pump or carried in pomace carts or tubs.
