The white grape variety is a new breeding between Colombard x Vernaccia Sarda. It is possible that this is the variety Vernaccia di Oristano; however, it is not clearly certain which of the many Vernaccia varieties it actually is. The crossing was done in California in the 1960ies by the private breeder Fay Triplett (1904-2000), the selection in the mid-1980ies in cooperation with the University of California and the Californian wine multinational Gallo. The high-yielding vine yields acid-accentuated, fruity, full-bodied white wines. In 2016, U.S.-California reported a total acreage of 412 hectares, with a strong upward trend, as in 2010 there were 244 hectares (Kym Anderson statistics).
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
