Rkatsiteli
Also known as: Dirakhvis Tetri, Rkaziteli, Topolyak
Most agronomically defensible speculative white: documented cold hardiness, late budbreak, natural disease resistance, Cornell-trialed, easiest to source via East Coast nurseries.

Considerations
Primary buds start to die near -15°F. Handles a normal cold-climate winter, but a hard freeze is a risk.
Needs roughly 3050 growing degree-days to ripen, a late-season variety (Winkler III). Wants a long, warm season; marginal in cool regions.
Foliar-disease pressure is heavy for this variety, a intensive spray program in a humid climate. Plan on a full, well-timed fungicide schedule.
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.
High heat tolerance. Holds up to a hot, sunny season.
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.
