What is "erbaluce"

Erbaluce or Erbaluce bianca is a white Italian wine grape grown primarily in the Piedmont region around Caluso, in Canavese. In addition to dry table wines, it is used to make sweet wines passito with deep golden coloring. The grape has a long history in the Piedmont region, with the first written record dating to 1606, and most likely originated in the alpine hills of northern Piedmont.

In the 21st century, DNA profiling determined that Erbaluce has a close genetic relationship with another Piedmontese wine grape, Cascarolo bianco, though the exact nature of that relationship is not yet known.
