Comments	Zinfandel is the only important Vitis vinifera wine variety closely identified exclusively with California. It is believed that Zinfandel came to California via New York from the Austro-Hungarian Empire (which at the time included Croatia) around 1850. It was developed into the fourth leading wine grape variety in California. Genetic comparison showed that Zinfandel, Primitivo (Italy), Crljenak kaštelanski and Tribidrag/Pribidrag (Croatia) share the same DNA profile. Recent research from Croatia indicates that this variety was most likely known as Tribidrag when it was grown in Croatia centuries ago.

Zinfandel Selections

Information about: Selection Numbers | Registration Status

How Selection Numbers are Created

Questions are often asked as to how Foundation Plant Services (FPS) decides which number to assign to the grape selections in the foundation vineyard and whether those numbers relate to particular clones that may be the sources of the FPS selections.

The answer for most selections in the FPS foundation vineyard is that selection numbers are assigned by the next available (unused) number in sequence for that variety. There is nothing magical about it. For example, the first Sauvignon blanc selection that came to FPS in 1958 was named Sauvignon blanc FPS 01. The next Sauvignon blanc arrival received the name Sauvignon blanc FPS 02. Gaps in the numbering system in the current list of available selections mean that the omitted number was taken out of circulation for some reason, such as death from disease.

FPS intentionally chose the word "selection" rather than "clone" when referring to the products offered in the foundation vineyard. The word "clone" can be confusing and ambiguous. The major European collections have formal evaluation protocols for grape material to qualify material for release as an official "clone". Evaluation criteria includes field performance and wine making characteristics.

FPS does not perform formal clonal evaluations on the grapevine materials accepted for the foundation vineyard. The word "selection" at FPS simply means the material was collected from a single source vine from the vineyard of origin, whether within the United States or from a foreign vineyard. Some of our numbered selections have been through trials here in California but FPS does not conduct those trials or evaluations.

Having said that, there is a subgroup of selections at FPS that are official numbered clones from the formal clonal development programs in Europe. Those official clones are imported and sold by the owners as proprietary (trademarked) clonal material in the United States. The owners are large government or nursery entities in Europe, such as the ENTAV-INRA® clonal material from the IFV program in France. In order to preserve the identity of those clones, FPS agreed to assign them the same official clone number that the program in Europe gave them when released there. Cabernet Sauvignon 685 from France received the name Cabernet Sauvignon ENTAV-INRA® 685 at FPS. The owners of those proprietary clones are the ones who vouch for or affirm the authenticity of their trademarked clones.

Lastly, there is a small subset of "clones" that came to FPS in the 1980's prior to the establishment of the trademark programs for the European clones. Those clones also came to the United States associated with clone numbers assigned when the clones were developed in Europe. Many of the French clones in that group were developed at Dijon in France and the material has been known as the "Dijon clones". Those French clones were not protected by an official trademark program at the time they came to the United States. Some of those clones are no longer used in France and some were incorporated into the ENTAV-INRA trademark program.

FPS refers to this subset of clones as "generic clonal material". FPS agreed that we would assign those non-proprietary clones a new number at FPS rather than the European clonal number. They received their FPS numbers using the "next in order" rule. We may have a note on the plant description that the selection is "reported to be a certain French clone number". FPS cannot guarantee that such a selection is the official French clone number that it was formally associated with in France.

Comments	Zinfandel 01A and Zinfandel 02 came to FPS in 1961 from a vineyard in Lodi owned by Leon Handel. The climate in the Lodi-Woodbridge area is amenable to growing good quality Zinfandel grapes due to the marine influences which permeate the San Joaquin Delta region of the Central Valley. San Joaquin County has led the state in total Zinfandel acreage since the middle of the last century. (Sullivan, C.L., 2003). Statistics reported by CDFA in the 2006 Grape Acreage report show that the San Joaquin Valley now has ~20,200 acres of Zinfandel (including Primitivo) of the ~50,000 acres of Zinfandel grapes planted in California. The original plant material from Lodi tested negative for virus. Zinfandel 01A and 02 were registered in the California Grapevine Registration & Certification Program in 1962 without any kind of virus elimination treatment. Both selections are still available from FPS as California foundation stock. A tissue-cultured version of Zinfandel 01A has qualified for the Russell Ranch Foundation Vineyard (see Zinfandel 01A.1)

Comments	The California Heritage Zinfandel Project is an ongoing collaboration between Zinfandel Advocates and Producers (ZAP) and the University of California. The Zinfandel clones in the project were collected in the 1990's from historic old vine plantings in geographically diverse regions throughout California. The pre-1930’s vineyards were located in fourteen California counties, from Mendocino to San Bernardino. The team specifically sought vines with loose clusters and small berries. Evaluation and wine trials have been conducted on the clones since 1997. The identity of the clones has been reserved during the evaluation period in order to encourage objective assessments. This selection was originally designated Zinfandel Heritage clone 5, and the source remains confidential at this time. In 2014, ZAP revealed the identity (source) of four of the Heritage Zinfandel clones after publication of the results of a taste testing. The identity of those four clones is: Zinfandel FPS 10/15.1 (Teldeschi Vineyard, Dry Creek, Sonoma County), Zinfandel FPS 24/24.1 (Lytton Springs Vineyard, Sonoma County), Zinfandel FPS 25/25.1 (R.W.

Comments	Zinfandel 13 is a proprietary selection owned by Novavine Grapevine Nursery in Santa Rosa, California. The original plant material came to Foundation Plant Services in 1999 from an old vine Zinfandel vineyard owned by Milton and Ellen Heath. The vines of the Nova Zinfandel clone are grown in sandy loam soil on the Kelseyville benches (1300-2000 feet) at the base of Mount Konocti in Lake County. Jim Smith, who manages the source vineyard in Lake County, explained: “ The vines [of this clone] yield a versatile grape that is very ‘fruit forward’ with a nose that ‘jumps out of the glass’. Spiciness can be dictated by an open canopy (very fruity) or an extra-shaded canopy (heavy peppery characteristics).” Five wineries – Wild Hog, X Winery, DeLoach, Hall Crest, Jelly Jar - have produced unique and very different wines composed almost solely of fruit from this clone. All tests on Zinfandel 13 at FPS were negative for viruses, and it first appeared in the California Grapevine Registration & Certification Program in 2006. Plant material for Zinfandel 13 can be obtained through NovaVine, Inc., in Santa Rosa, California.

Comments	The California Heritage Zinfandel Project is an ongoing collaboration between Zinfandel Advocates and Producers (ZAP) and the University of California. The Zinfandel clones in the project were collected in the 1990's from historic old vine plantings in geographically diverse regions throughout California. The pre-1930’s vineyards were located in fourteen California counties, from Mendocino to San Bernardino. The team specifically sought vines with loose clusters and small berries. Evaluation and wine trials have been conducted on the clones since 1997. The identity of the clones has been reserved during the evaluation period in order to encourage objective assessments. Zinfandel FPS 25 was originally labeled "Heritage clone 38". In 2014, ZAP revealed the identity of four of the Heritage Zinfandel clones after publication of the results of taste testing. Zinfandel FPS 25/25.1 was collected from the R.W. Moore Vineyard in the Napa Valley Coombsville appellation. This clone has qualified for the Russell Ranch Foundation Vineyard at Foundation Plant Services as Zinfandel 25.1. The other three clones that were identified in 2014 were Zinfandel FPS 24/24.1 (Lytton Springs Vineyard, Sonoma County), Zinfandel FPS 10/15.1 (Teldeschi Vineyard, Dry Creek, Sonoma County) and Zinfandel FPS 26/26.1 (Zeni Ranch, Mendocino County).

Comments	Zinfandel FPS 43.1 was formerly known at FPS as Pribidrag FPS 01. The name was changed to Zinfandel to reflect the preferred name for the cultivar in the United States. Zinfandel 43.1 is Pribidrag clone VV-079 from Svinšce, Croatia. Svinšce is near the Dalmatian coastal town of Omiš, Croatia. The selection was imported to Foundation Plant Services in 2005 as a joint proprietary selection for Ridge Vineyards and the University of Zagreb in Croatia. The original material tested positive for virus and underwent microshoot tip tissue culture disease elimination therapy in 2007. The selection successfully completed disease testing in 2011 and qualified for the California R&C Program, initially as Pribidrag 01. The selection was renamed and given a new selection number in 2012. FPS has two other unique 'Pribidrag' clones: Zinfandel FPS 44.1 (formerly Pribidrag FPS 02) is Croatian clone VV-101 also from Svinšce; and there is a third clone from Marusici, Croatia, that is still in the testing/treatment process at FPS.
