Considerations
Primary buds start to die near -10°F. Handles a normal cold-climate winter, but a hard freeze is a risk.
Needs roughly 2400 growing degree-days to ripen, an early-season variety (Winkler I-II). Finishes early, well before a hard fall frost.
Foliar-disease pressure is moderate for this variety, a regular spray program in a humid climate. Regular cover sprays through the wet months.
Susceptible to Pierce's disease. Only a threat in the warm, humid South and parts of California; cold-winter regions cure it naturally.
Moderate vigor. Easier to balance; tolerates more fertile ground.
Moderate heat tolerance. Comfortable across a moderate heat range.
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-tolerant: own-rooted vines are fine.
These are intrinsic to the grape. On a real property, Folia scores each against your site; here they're shown on their own.
