Considerations
Primary buds start to die near 5°F. Cold-tender; wants a mild winter or protected site.
Needs roughly 3300 growing degree-days to ripen, a late-season variety (Winkler III). Wants a long, warm season; marginal in cool regions.
Resistant to Pierce's disease. Only a threat in the warm, humid South and parts of California; cold-winter regions cure it naturally.
High heat tolerance. Holds up to a hot, sunny season.
Moderate water demand. Average moisture needs for a wine grape.
Prefers soil pH between 5.5 and 7.5. 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.
