Its introduction raised the standard of quality in our viticulture to that of the Old World, for there is no variety of _Vitis vinifera_ more richly or more delicately flavored or with a more agreeable aroma than the Delaware. This variety is rightly used wherever American grapes are grown as the standard whereby to gauge the quality of other grapes. Added to high quality it is endowed with a constitution which enables it to withstand climatic conditions to which all but the most hardy varieties will succumb, and so elastic as to adapt it to many soils and conditions, and to bear under most situations an abundant crop. All of this makes it, next to the Concord, the most popular grape for garden, vineyard and wine-press, now grown in the United States. As with the Concord, its introduction gave American grape-growing a great impetus and it is a question whether or not, with its high quality, it has not had a more beneficial effect on the viticulture of the country than the Concord.
