All of the regions we have been discussing, in which native grapes are grown, show a considerable falling off in production excepting the eastern one where the increase more than counterbalances the decrease in the other regions. The census report for 1900 shows three new states in the list of those producing grapes in commercial quantities. In the decade preceding, Michigan came up from an insignificant commercial production in 1890 to fifth rank in 1900 with 20,765 tons. Iowa and Oklahoma, states from which grapes were not reported in commercial quantities in 1890, produced 3701 and 3055 tons in 1900.
The shifting of grape areas indicated in the above paragraph was caused for most part by the grape diseases. The mildew and rot had ruined the grape industry in some of the older regions. The newer regions, as in Michigan, either enjoy comparative immunity from these troubles or the vineyards had not yet been attacked by them. In the case of the eastern region, New York and Pennsylvania, in the Chautauqua district, along the shores of Lake Erie in both states, where the production increased greatly during this decade, the vineyards are almost wholly immune to black-rot and are comparatively free from the mildew. In the other grape districts of this region these troubles are kept well in check by spraying.
The statistics given in the last few paragraphs show how greatly the grape-growing of eastern America has increased in the last half century. When one considers that at the time Erskine made his survey in 1859 there were but 6100 acres of grapes in the whole of this great region and that the culture of the European varieties was impossible, the total acreage grown in 1900, namely, 237,998 acres, makes an astounding figure. The results achieved seem all the greater when one considers that many of the best varieties now grown are the first and scarcely any are further removed than the second generation from wild plants. It is doubtful if any other cultivated plants have attained such importance as our native grapes in so short a time from the wild state. Yet their domestication has scarcely begun and few who grow them realize their possibilities.
THE WINE[86] AND GRAPE JUICE INDUSTRIES.
For over 200 years the grapes grown on this continent were almost wholly for wine-making. Yet the production of grapes was not sufficient to sustain a wine industry until the middle of the nineteenth century. When, with the introduction of new varieties of grapes and of better methods of growing them, the crop became sufficient in volume to support wine-making as an industry, its progress was checked by the enormous demand for table grapes, a demand not known in other countries, and by the cheapness of California wines. Furthermore the grapes most commonly cultivated, as the Concord, Worden and Niagara, do not make good wines; and knowledge and facilities for wine-making have not been such that the best wines could be made with varieties adapted for the purpose. All of these obstacles, to which we may add the fact that Americans are not a wine-drinking people, have prevented the building up of a wine industry as it exists in other grape-growing countries.
Although the United States stands second or third in the list of grape-producing countries it took lowest rank in wine production in 1900, falling below the small countries of Greece and Switzerland and such comparatively undeveloped countries as Chili and Argentine. Since by far the greater proportion of American wines come from the European grapes of the Pacific coast, it can be seen that wine made from American grapes is but a drop in the bucket in the world’s production. Reliable statistics of viticulture in the United States were not taken until 1890, but careful estimates, as we have seen, had been made by several men at different periods. These with the last two census reports show the output of wine in this country to be, in round numbers, as follows:
| Gallons | |
| 1850 | 250,000 |
| 1860 | 500,000 |
| 1870 | 5,000,000 |
| 1880 | 15,000,000 |
| 1890 | 24,000,000 |
| 1900 | 30,000,000 |
According to the American Wine Press,[87] the leading authority on wines in this country, the vintage of 1907 shows the following figures:
| Gallons | |
| Southern States | 1,000,000 |
| New Jersey | 250,000 |
| New York | 4,000,000 |
| Ohio | 2,500,000 |
| Missouri | 1,500,000 |
| California, dry | 30,000,000 |
| California, sweet | 10,000,000 |
| Western States | 500,000 |
| All other States | 500,000 |
| Total wine yield | 50,250,000 |
Subtracting the product of California from the total we have approximately the yield of wine from native grapes.
