Burger is an old, high-yielding white grape of uncertain origin, its name maps to more than one entry in the international varietal registry, so its exact identity is unresolved, that was once a high-volume Central Valley grape for bulk and jug white wine. California's ledger shows a long decline: bearing acreage fell from 1,837 acres to 1,093 acres and now sits at 763 acres in 2025, spread across ten counties and 162 county-years of reporting. It is grown almost entirely for volume rather than character, and was planted historically for heavy cropping more than flavor.

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

2 wines from 1 producer, each read from that producer’s own tech sheet and linked to it. No average is shown, and none should be computed from these. Wineries that publish tech sheets are selected by their own marketing departments, so a mean across them describes publishing habits rather than a grape.
