Grape Spotlight: Croatian Tribidrag (Crljenak Kaštelanski, Pribidrag, Kratošija) aka Zinfandel

"When I came to America in August 1958, I saw vineyards around Chateau Souverain and I was interested to know which grapes were grown there. They told me Cabernet Franc from France and Zinfandel, but no-one knows where those grapes came from.  .... These Zinfandel grapes reminded me of the Plavic Mali grapes from my homeland in Croatia. ... I contacted Dr. Carole Meredith to tell her that I believed Zinfandel, Italian Primitivo, and Croatian Plavic Mali were the same grape. "  Miljenko "Mike" Grgich addressing the First International Conference on the Tribidrag Variety

Grgich's instincts were close. The idea that California Zinfandel was equivalent to Italian Primitivo was also proposed by UC Davis professor Austin Goheen and Wade Wolfe in the 1960s. Goheen visually inspected Primitivo from Puglia (Southern Italy) and considered them identical whereas Wolfe used isozyme analysis to strengthen that hypothesis. But it wasn't until 1995, after three years of DNA analysis, when Dr. Carole Meredith, Professor at UC Davis, concluded that Zinfandel and Primitivo were, in fact, the same grape variety.

Based on Grgich's recommendation, Dr. Meredith then traveled to Croatia in 1998 and,  working with Dr. Edi Maletić and Dr. Ivan Pejić, collected 150 Plavic Mali samples. Returning to UC Davis for testing the results were negative, close, but not identical. Dr. Meredith concluded that either Zinfandel or Plavic Mali was the parent of the other but couldn't determine the parental direction. Dr. Maletić and Dr. Pejić continued the search in Dalmatia, often walking row after row in small family vineyards. Eventually, they sent Dr. Meredith samples of an obscure variety called Crljenak Kastelanski that they had collected near Kastel. Actually two sets of samples with the second being an exact match. And more research showed that Plavic Mali was the offspring. Fortunately for our pronunciation, the Crljenak Kastelanski grape was also called Tribidrag and the oldest name used in Croatian literature dated to the 15th century. Thus Croatia is the ancient homeland for California Zinfandel. (One and the same? – Zinfandel, Primitivo, Crljenak Kaštelanski and Kratošija)

Well, not so fast my friend. Croatia's southern neighbor Montenegro claims that distinction based on the Montenegrin autochthonous grape Kratosija which is genetically identical to Tribidrag. Montenegrin wine enthusiast Vlado Nikaljević presents an intriguing argument that the grapes provided to the Vienna World Fair that eventually became the foundation for California Zinfandel came from Montenegro and "Venetian archives show that the Statute of the Venetian Budva mentions Kratošija 60 years before the Tribidrag references". (Montenegro - the True Homeland of Zinfandel)

Thus, Zinfandel's homeland is - to be continued....

In the meantime, a second wave has taken Croatian Tribidrag to California. Ridge Vineyards, among other California wineries,  planted Croatian selections in their Lytton Springs vineyard. They will label wine from these grapes Croatian Zinfandel since the TTB doesn’t recognize Zinfandel and Tribidrag as synonyms. Expect an update on these wines soon.

This evening I just finished sipping a Dalmatian made Croatian Tribidrag - the 2016 Rizman Winery Tribidrag ($45) - available for purchase through Croatian Premium Wine Imports. The wine includes 15% Tempranillo and is sourced from the winery's organic vineyards in the Komarna winegrowing area between Split and Dubrovnik. The south-facing slopes are steep and comprised of limestone soils. The result is a chalky old world styled wine with linear fruit, approachable and chewy tannins, and lengthy acids.
The Ridge Lytton Springs Tribidrag apparently has a similar structure -- particularly the strong acidity.

During this CV pandemic, Croatian Premium Wine Imports is conducting weekly Wednesday night virtual chats and this Rizman is the focus on the chat for tomorrow April 15th. (Funny when I wrote that final date, I immediately panicked about my taxes.)  Hope to see you online at 8pm ET. Cheers.

Do You Know Your Croatian Grape Varieties?

I'm less familiar with Croatian grape varieties as I am with Hungarian, but this last trip to Hrvatska expanded my knowledge. Like Hungary, Croatia has a long wine tradition dating back to pre-Roman periods with many wins favored by nobility throughout Europe. Here is a subset of Croatian grape varieties to start your studies.

Crljenak Kaštelanski (Tribidrag) (r)
Crljenak Kaštelanski was an almost extinct Dalmatian grape varietal until DNA fingerprinting revealed that it was an exact DNA match to both Zinfandel and the Italian grape Primitivo. It was once the most dominant red grape in Dalmatia with written records reaching back to the 15th century but susceptibility to disease lead to its decline. Yet after the DNA match the grape is being replanted with the advantages of ripening early and needs less sun than its child Plavac Mali (plus produces less tannins). Try the Dubrovački Podrumi Crljenak Kaštelanski.

Plavac Mali (r)
Grown throughout Dalmatia as a replacement to the disease ridden Crljenak Kaštelanski and now the most important red wine grape in Croatia. Plavac means blue, and Mali means small but this offspring of Crljenak Kaštelanski and Dobričić packs a punch with cherry flavors, spice, and tannins. The high alcohol and acidity lead to solid aging potential as in the Plavac Mali wines from Miloš Winery.

Graševina (w)
Although not indigenous to Croatia, Graševina (Welschriesling, Olascsrizling in Hungary, and Laški Rizling in Slovenia) is the most widely planted wine grape - particularly in Slavonia where it thrives on cooler soils and a continental climate. It is intended to be consumed young and shows its popularity and the Croatian equivalent of boxed wine. However for those producers producing a deeper style, minerality replaces some of the fruity and flowery characters with the remaining crisp acidity. The Krauthaker Graševina Mitrovac was one we discovered. There's also the Adžić Winery Graševina available in the U.S.

Malvasia Istriana (w)
Malvazija (Malvasia in Italian) comes from the Istria peninsula and is known for creating intense wines that can be drunk young like a fresh Sauvignon Blanc or barrel aged for a more complex style. One of these with excellent minerality is the Piquentum Malvazija Blanc.

Debit (w)
Debit grows best in the central and north coast of Croatia and is characterized by golden yellow grapes that provide green apple flavors and abundant citric acidity. Try the Bibich Winery Debit

Pošip (w)
A popular grape coming from Dalmatia and associated with islands of Hvar and Korčula. These wines are flavorful, rich and textured with strong aromas and refreshing notes. Toreta Winery is a large producer of this grape.

Babić (r)
Babić are blue wine grapes grown mostly in Dalmatia. These are full bodied wines featuring dark berries, plums, and figs, as well as distinct spices. The Bibich R6 Riserva blend is a great example.

Bogdanuša (w)
This grape is native to the island of Hvar in Central Dalmatia, translates to “a godsend”, and is traditionally drunk during religious festivals. The Carić Vina is the only version of this wine exported to the U.S.

Dobričić (r)
This grape is from the island of Šolta (near Split) and with Crljenak Kaštelanski is the other parent of Plavac Mali. The grapes are extremely dark red and creates a purple wine -- sometimes called “the darkest wine of Dalmatia”. The grapes do not produce much sugar so varietal wines are low in alcohol as well as extremely low in acids. But be prepared for a tannic tail to create s bitter sour cherry finish. While visiting Šolta stop by Agroturizam Kaštelanac to taste different styles of Dobričić.

Vrbnička Žlahtina (w)
Vrbnička Žlahtina is mostly grown on the island of Krk, the largest of Croatia’s 1000+ islands, and benefits from colder climates. It produces light, refreshing white wines with floral and white fruit aromas. Try the Šipun Žlahtina.

Teran (r)
Up until a century ago, this grape was the most widely planted in Istria. In best of times the wine is "ruby-red, almost purple wine of a typical, fruity aroma that is easy to recognize, and has hints of berries and pepper, unusually high acidity and high tannins and not too high alcohol content: 12 – 13%". Good luck finding it outside of Istria since there is an EU dispute with Slovenia over naming rights.

Dingač (r)
Dingač is not a grape but a Plavac Mali wine produced in the Pelješac sub-region of the Middle and South Dalmatia wine growing region. Its included here because there can be some confusion on its definition.
