The society had discussed offering the £200 to both men for their achievements. However, the Society raised concerns about the legitimacy of Alexander's claim to a title of nobility. On 2 December 1767, the Society offered the cash award to Antill, and three weeks later offered Lord Stirling a gold medal "for having planted 2100 vines in North America in pursuance of the Views of the Society." Shortly after his death, Antill published an 80-page tract entitled "An Essay on the cultivation of the Vine, and the making and preserving of Wine, suited to the different Climates in North-America" (1771) and this account influenced scholarship well into the nineteenth century.
