Souzao is a Portuguese red grape, one of the traditional port varieties, used for deep color and high acidity in fortified wine. California's numbers show a small, stable planting: bearing acreage sat at 90 acres five years before the present and 82 acres in the latest report, spread across 15 counties. It is used here almost entirely for port-style and other fortified reds, where its acidity and color hold up well against added spirit, and its acreage has stayed remarkably steady rather than expanding or shrinking.

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