Blaufraenkisch is Austria's leading red grape, bred from Zimmettraube Blau and Heunisch Weiss, known for peppery spice, dark fruit, and high acidity in cooler climates. California's data shows it crushed in every one of the last 26 vintages across 8 districts, but with zero acres ever recorded in the acreage report and no UC Davis Foundation Plant Services registry entry, meaning the state has no verified source of certified planting material for it. It survives here as a small, likely uncertified planting by growers drawn to Central European cool-climate reds rather than as a tracked commercial variety.

What is published
Counts describe what this atlas holds for Blaufraenkisch, not what California grows. A zero is a published answer: it means the source names the grape and reports nothing under it, or does not name it at all.
