Considerations

Winter hardiness≈ -8°F
TenderVery hardy

Primary buds start to die near -8°F. Cold-tender; wants a mild winter or protected site.

Season needed2050 GDD
Early / shortLate / long

Needs roughly 2050 growing degree-days to ripen, an early-season variety (Winkler I-II). Finishes early, well before a hard fall frost.

Spray / disease loadintensive
HeavyLight

Foliar-disease pressure is heavy for this variety, a intensive spray program in a humid climate. Plan on a full, well-timed fungicide schedule.

Pierce's diseaseSusceptible
SusceptibleResistant

Susceptible to Pierce's disease. Only a threat in the warm, humid South and parts of California; cold-winter regions cure it naturally.

VigorHigh
LowHigh

High vigor. Wants leaner ground and active canopy management, or fruit hides in shade.

Heat toleranceLow
Cool-climateHeat-loving

Low heat tolerance. Bakes and loses acid on hot sites; favors cooler ground.

Water demandModerate
Drought-adaptedThirsty

Moderate water demand. Average moisture needs for a wine grape.

Soil pH window6.0–7.0
Acidic 4.5Alkaline 8.5

Prefers soil pH between 6.0 and 7.0. Outside the band, lime or sulfur brings it in range.

RootstockGraft
Own-rooted OKGraft required

Phylloxera-susceptible: plant grafted onto resistant rootstock.
