A little online research revealed that no paranormal activity was involved. The wine grapes growing beside the fairways are the project of Douglas Johnstone, president of the Golf Center of Staten Island, which runs the Silver Lake Golf Course. As of 2009, the intent was to produce a vintage called Skye Dog Wine from plantings of Corot noir and noiret grapes. However, a lack of recent updates suggests that the project, like so many earlier attempts at wine making in New York, proved more challenging than anticipated. I am sure Stephen Jumel could provide useful advice, if anyone knew how to channel it.
