I found this interesting information:
This hearty red is Sicily's most popular non-fortified varietal, now

produced by numerous Sicilian wineries. Often compared to Syrah, it is sometimes blended with other reds but usually allowed to stand on its own. A full-bodied red like this one is not easily overlooked, and dozens of wineries (including makers of "
new wines") have introduced this varietal to cash in on a profitable trend.
