Crljenak Kaštelanski

Crljenak Kaštelanski has been cultivated in Dalmatia since at least the 15th century, with the earliest recorded mention of its synonym Tribidrag dating to 1444 in Kaštela, a string of coastal towns near Split. From there, the grape traveled to Italy in the 18th century, where it became known as Primitivo, and then reached North America via Vienna in the 1820s, eventually taking hold in California as Zinfandel. Back in Croatia, phylloxera and disease pressure pushed the variety to near extinction. By the late 20th century, it had all but disappeared.

• First documented as Tribidrag in 1444 in the Kaštela region of Dalmatia
• Transported to Italy in the 18th century, becoming Primitivo; reached California in the 1820s as Zinfandel
• Nearly wiped out by phylloxera and susceptibility to powdery mildew and uneven ripening

In 2001, a team from UC Davis led by Dr. Carole Meredith confirmed through DNA analysis that Crljenak Kaštelanski was genetically identical to Zinfandel and Primitivo. The breakthrough came from a single vineyard in Kaštel Novi containing just nine surviving vines. Additional vines were located in Omiš in 2002. The discovery triggered a revival: from those 22 vines documented in 2001, cultivation expanded to approximately 2,000 vines by 2008 and continues to grow today.

• UC Davis team led by Dr. Carole Meredith confirmed identity in 2001 at Kaštel Novi
• Only nine vines were found at the discovery site; 22 vines total documented in 2001
• Additional vines discovered in Omiš in 2002, supporting the revival effort
• Vine count grew from 22 to approximately 2,000 by 2008

Crljenak Kaštelanski grows in the Kaštela region of Dalmatia along Croatia's Adriatic coast. The soils are limestone-based with red clay topsoil and rocky terrain. The climate is Mediterranean, with warm dry summers and mild wet winters along the coast, moderated by the bura, a cold northeasterly wind that sweeps down from the mountains. The grape ripens approximately one month earlier than Plavac Mali, the variety it parentaged, and is considered challenging to grow due to susceptibility to powdery mildew and uneven cluster ripening.

• Limestone and red clay soils with rocky terrain in the Kaštela appellation
• Mediterranean coastal climate with bura wind influence
• Ripens about one month before its offspring Plavac Mali
• Susceptible to powdery mildew and uneven ripening; not a hardy variety

Crljenak Kaštelanski produces deep ruby, medium to full-bodied dry red wines with medium to high alcohol. The flavor profile centers on ripe blackberries, plum, and dark cherries, with supporting notes of black pepper, licorice, herbs, and subtle vanilla. Tannins are supple. Style varies from robust, concentrated reds with genuine aging potential to more fruit-driven, approachable versions depending on producer and site. The approximately 20 significant producers now working with the grape in Croatia give a growing picture of its range.

• Deep ruby color, medium to full-bodied with medium to high alcohol
• Core flavors of ripe blackberry, plum, dark cherry, black pepper, and licorice
• Supple tannins with subtle vanilla notes from oak
• Styles range from concentrated age-worthy reds to fruit-forward approachable wines

The grape's identity as the source of both Zinfandel and Primitivo makes it one of the most historically significant varieties in the world. Tribidrag is now considered the oldest documented name for the variety, predating Italian records by more than 350 years. Ridge Vineyards in California is actively propagating Croatian clones of Crljenak Kaštelanski at its top cru vineyards, including Lytton Springs and Geyserville, connecting the modern story of Zinfandel back to its Dalmatian origins.

• Tribidrag is the oldest documented name, recorded 355 years before 'Zinfandel' appeared in print
• Genetically identical to Primitivo (Italy) and Kratošija (Montenegro) as well as Zinfandel (California)
• Ridge Vineyards propagating Croatian clones at Lytton Springs and Geyserville in California
