Pinot Kors
Also known as: UD 156-537
Second-wave PIWI red off Pinot Noir, two downy loci plus Run 1. Loose winged cluster on a horizontal habit. VCR publishes NO cold figure for this one, so its winter limit here is the program-level -20C objective, not a variety reading.

Considerations
Primary buds start to die near -4°F. Cold-tender; wants a mild winter or protected site.
Needs roughly 2550 growing degree-days to ripen, a mid-season variety (Winkler I-II). A mid-length season carries it most years.
Foliar-disease pressure is light for this variety, a routine spray program in a humid climate. One of the easier vines to keep clean.
Susceptible to Pierce's disease. Only a threat in the warm, humid South and parts of California; cold-winter regions cure it naturally.
High vigor. Wants leaner ground and active canopy management, or fruit hides in shade.
Low heat tolerance. Bakes and loses acid on hot sites; favors cooler ground.
Moderate water demand. Average moisture needs for a wine grape.
Prefers soil pH between 6.0 and 7.0. Outside the band, lime or sulfur brings it in range.
Phylloxera-susceptible: plant grafted onto resistant rootstock.
These are intrinsic to the grape. On a real property, Folia scores each against your site; here they're shown on their own.
