Royalty is a California-bred teinturier grape, a red-fleshed variety bred by crossing Alicante Ganzin with Trousseau specifically to add color to blends. The state's own numbers show a variety in steep decline: bearing acreage started at 732 acres, fell to 230 acres five years before the present, and now sits at just 171 acres in 2025, spread thinly across five counties. Like other teinturiers, it is not grown to be bottled on its own; its whole purpose is to deepen the color of cheaper red blends, a role increasingly filled by other grapes.

What is published
Counts describe what this atlas holds for Royalty, 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.
