At the meeting of the American Philosophical Society in Philadelphia, July 19, 1768, it was resolved that the "Society would be obliged to any gentleman that would communicate to them any method of making wine of the American grape, without sugar or water, or the best way of making it with that addition;" and at the meeting of September 20th "a specimen was exhibited by Dr. Syng of wine made of the small black American grape, without water or sugar, in 1765, which appears to be perfectly sound and delicious to the taste," as the minutes of the Society of that date record. This was no doubt the Vitis cordifolia, the species that has given us the Clinton, so that this species may be regarded as among the earliest to give a good American wine.
