The Swedes made some attempts at an early day to grow grapes on the Delaware. Queen Christina instructed John Printz, governor of New Sweden, to encourage the "culture of the vine" and to give the industry his personal attention. Later when New Sweden had become a part of Pennsylvania, William Penn encouraged vine-growing by importing cuttings of French and Spanish vines; and several experimental vineyards were set out in the neighborhood of Philadelphia, but all efforts to establish bearing plantations came to naught. Penn's interest in grape-growing seems to have been greatly stimulated by wine made by a friend of his from native grapes which grew about Germantown. There are no detailed accounts of grape-growing by the Dutch of New York but the following taken from the writings of Jasper Dankers and Peter Sluyter, two Hollanders who visited New York in 1679, soon after the English took possession of New Netherland, indicates that there had been attempts to cultivate grapes.[13] "I went along the shore to Coney Island, which is separated from Long Island only by a creek, and around the point, and came inside not far from a village called _Gravesant_, and again home. We discovered on the roads several kinds of grapes still on the vines, called _speck_ (pork) grapes, which are not always good, and these were not; although they were sweet in the mouth at first, they made it disagreeable and stinking. The small blue grapes are better, and their vines grow in good form. Although they have several times attempted to plant vineyards, and have not immediately succeeded, they, nevertheless, have not abandoned the hope of doing so by and by, for there is always some encouragement, although they have not, as yet, discovered the cause of the failure." The "_speck_" grape was without question _Vitis labrusca_ and the small blue grape was probably _Vitis riparia_.
