The grapes of New York

by U. P. Hedrick

“Be mindful, when thou hast entomb’d the shoot,
With store of earth around to feed the root;
With iron teeth of rakes and prongs, to move
The crusted earth, and loosen it above.
Then exercise thy sturdy steers to plow
Between thy vines, and teach the feeble row
To mount on reeds, and wands, and, upward led,
On ashen poles to raise their forky head,
On these new crutches let them learn to walk,
’Till, swerving upwards with a stronger stalk,
They brave the winds, and, clinging to their guide,
On tops of elms at length triumphant ride.”[3]

His directions for pruning are equally fitting for present practice:—

“But in their tender nonage, while they spread
Their springing leaves, and lift their infant head,
And upward while they shoot in open air,
Indulge their childhood, and the nurslings spare;
Nor exercise thy rage on new-born life;
But let thy hand supply the pruning knife,
And crop luxuriant stragglers, nor be loth
To strip the branches of their leafy growth.
But when the rooted vines with steady hold
Can clasp their elms, then, husbandman, be bold
To lop the disobedient boughs, that strayed
Beyond their ranks; let crooked steel invade
The lawless troops, which discipline disclaim,
And their surperfluous growth with rigor tame.”

The history of the development of the vine from Vergil’s time through the early centuries of the Christian Era and of the Middle Ages to our own day, is largely the history of agriculture in the southern European countries; for the vine during this period has been the chief cultivated plant of the Greek and Latin nations. This history should furnish most instructive lessons in grape-growing and in grape-breeding.

But interesting and profitable as a detailed account of the development of the Old World grape would be, the brief outline in the few preceding paragraphs must suffice for this work. The reader who desires further information may find it in the agricultural literature in many languages and dating back two thousand years.

What are the characters of the European grape and how does it differ from the native grapes of America? The Old World grape is grown for wine; the American grapes for the table. The differences in the fruit of the vines of the two continents are largely the differences necessary for the two distinct purposes for which they are grown. The varieties of Vitis vinifera have a higher sugar and solid content than do those of the American species. Because of this richness in sugar they not only make better wine but keep much longer and can be made into raisins. The American grapes do not keep well and do not make good raisins. Taken as a whole the European varieties are better flavored, possessing a more delicate and a richer vinous flavor, a more agreeable aroma, and they lack the acidity and somewhat obnoxious foxy odor and taste of many American varieties. It is true that there is a disagreeable astringency in some Vinifera grapes and that many varieties are without character of flavor, yet, all and all, the species produces by far the better flavored fruit. On the other hand, American table grapes are more refreshing; one does not tire of them so quickly as they do not cloy the appetite as do the richer grapes; and the unfermented juice makes a much more pleasant drink. The characteristic flavor and aroma of the varieties of Vitis labrusca, our most commonly cultivated native species, are often described by the terms “foxy”[4] or “musky.” If not too pronounced this foxiness is often very agreeable though, as with the flavor in many exotic fruits, the liking for it must often be acquired, and of course may never be acquired; yet the universal condemnation of this taste by the French and some other Europeans is sheer prejudice. The bunches and berries of the European grape are larger, more attractive in appearance, and are borne in greater quantity, vine for vine or acre for acre. The pulp and skin of the berries of Vitis vinifera are less objectionable than those of any native species and the pulp separates more easily from the seeds. The berries do not shell from the stem nearly so quickly, hence the bunches ship better.

In comparing the vines, those of the Old World grape are more compact in habit, make a shorter and stouter annual growth, therefore require less pruning and training. The roots are fleshier, and more fibrous. The species, taken as a whole, is adapted to far more kinds of soil, and to much greater differences in environment, and is more easily propagated from cuttings, than most of the species of American grapes. The cultivated forms of the wild vines of this country have few points of superiority over their relative from the eastern hemisphere, but these few are such as to make them now and probably ever the only grapes possible to cultivate in America in the commercial vineyards east of the Rocky Mountains. Indeed, but for the fortunate discovery that the vine of Vitis vinifera could be grown on the roots of any one of several species of the American grapes, the vineyards of the Old World grape would have been almost wholly destroyed within the last half century because of one of its weaknesses. This destructive agent is the phylloxera,[5] a tiny plant louse working on the leaf and root of the grape, which in a few years wholly destroys the European vine but does comparatively little harm to most of the American vines. Three other pests are much more harmful in the Old World vineyards than to the vines of the New World; these are black-rot (Guignardia bidwellii (Ell.) V. & R.), downy mildew (Plasmopara viticola (B. & C.) Berl. & De Toni), and powdery mildew (Uncinula necator (Schw.) Burr.).

The susceptibility of the Old World grape to these parasites debars it from cultivation in eastern America and so effectually that there is but little hope of any pure-bred variety of it ever being grown in this region. American viticulture must, therefore, depend upon the native species for its varieties, though it may be hoped that by combining the good qualities of the foreign grape with those of one or several of the species of this country, or by combining and rearranging the best characters of the native species, we may in time secure varieties equal in all respects to those of the Old World. The comparative resistance of the American species to the phylloxera, the mildews, and black-rot has been due to natural selection in the contest that has been waged for untold ages between host and parasite. The fact that the native species have been able to survive and thrive is a guarantee of the permanence of the resistance thus acquired.

We have said that the Old World grape is debarred from cultivation in eastern America. It is worth while considering how thorough the attempts to grow it in this region have been and to give a more exact account of the failures and their causes, for there are yet those who are attempting its culture with the hope that we may sometime grow some offshoot of Vitis vinifera in the region under consideration.

It is probable that the first European grapes planted in what is now American soil, were grown by the Spanish padres at the old missions in New Mexico, Arizona and California. Early accounts of some of these missions speak of grapes which must have been planted before settlements were made in eastern America. We need take no further account of these vineyards except to say that in this region the European grape has always been grown successfully, and that under the skilled hands of the mission fathers, ever notable vineyardists and wine-makers, these early plantings must have succeeded.
