Sorry Duster I can't help you. I never heard of the NY Muscat. But I did a google search and found this:
New York Muscat (Muscat Hamburg x Ontario). From Cornell University's Geneva, New York experiment station. This grape is always in the top three in tastings. The oval reddish-blue grapes have the best muscat flavor of any hybrid I have tried. Only pure vinifera muscats like Early Muscat or Muscat Hamburg are better in flavor, but they aren't as hardy as NY Muscat. The vine has less vigor such that where Concord would be planted eight feet apart, NY Muscat could easilly be planted six feet apart in the rows. Productivity is also lighter than many varieties. Even so, the flavor is worth it. Also used for sweet muscat wines in the eastern US. My vines do well trained to cordons and pruned to two or three bud spurs. Needs good soil fertility, too.
