Volturnis
Also known as: UD 156-312
Sold in a resistant lineup but carries NO powdery mildew resistance gene by VCR's own statement: downy only (Rpv 12). Powdery is scored susceptible here. High yield, good anthocyanin. The spray saving here is one-sided.

Considerations
Primary buds start to die near -4°F. Cold-tender; wants a mild winter or protected site.
Needs roughly 2600 growing degree-days to ripen, a mid-season variety (Winkler I-II). A mid-length season carries it most years.
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.
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.
