Gouais Blanc
Also known as: Branestraube, Heunisch Weiss, Liseiret
Extremely cold hardy, late budbreak, but commercially near-extinct: sourcing is the real barrier. More curiosity than candidate.

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.
