Pelješac Plavac Mali

In 1976, Mike Grgich's 1973 Chateau Montelena Chardonnay beat every French white in the Judgment of Paris — the tasting that proved France wasn't automatically supreme. At age 73, Grgich returned to Dalmatia and planted Plavac Mali on the Peljesac Peninsula. He died here at 100 in 2023. The tunnel to Dingač's vineyards was dug by hand between 1973 and 1975 because donkeys on goat paths were the only alternative. Plavac Mali is not Zinfandel's ancestor — it's the offspring. DNA proved in 2001 that the mother vine was nearly lost: only 9 plants found in a Kaštel Novi garden.

What to do there

5 things to do

1. 1 Drive Blind Through the Mountain the Farmers Dug By Hand Adventure · Free

   Where: Drive from Potomje village (320m above sea level) to the tunnel entrance on its western edge. Follow signs marked 'Dingač'. The tunnel mouth is cut directly into the limestone cliff face — there is no dramatic architecture. Just rock.

   What: In 1973, Dingač winemakers were still transporting their harvest on donkey-back, picking their way down goat paths for over an hour to reach the road. The journey to market was 20 kilometers. So they funded and dug a 400-metre tunnel through the mountain themselves — inaugurated November 29, 1975. It cut the route to 4 kilometers. This is the tunnel. It is unlit. It fits exactly one car. The walls are raw limestone.

   How: Before entering, check for headlights coming the opposite direction. If clear, drive through slowly — there are no lane markings, no lighting beyond your headlamps. The darkness lasts about 90 seconds. Then the rock opens and you're above Dingač: terraced vineyards at 45-degree angles plunging 300 meters straight toward the Adriatic. On a clear day you see Mljet and Korčula floating in the sea. This is the reveal moment — the whole reason to be here. Pull over on the wide shoulder immediately after the exit and stand at the edge.

   Backup: If traveling without a car, the tunnel can be walked (bring a torch/phone light). The view is identical on foot. From Orebić, take a bus to Potomje and walk the 1.5km from the bus stop.

2. 2 Taste the Wine the Man Who Beat France Made in His Homeland History · Price: moderate

   Where: Grgić Vina, Trstenik 78, Pelješac Peninsula — a stone winery on a headland above the Adriatic between Dingač and Postup. Open daily 9:00–19:00. The winery is perched directly above the sea; you'll see it from the coast road.

   What: On May 24, 1976, in a blind tasting at the InterContinental Hotel in Paris, an 11-person panel of French wine experts tasted two flights: California wines vs. the finest Burgundies and Bordeaux. The California Chardonnay that came first was the 1973 Chateau Montelena — made by Miljenko 'Mike' Grgich, a Croatian immigrant from a tiny Dalmatian village. The results were suppressed at first; when they leaked, they rewrote the wine world. California was real. France was not automatically supreme. Twenty years later, in 1996, Grgich came home. He founded this winery — Grgić Vina — with his daughter Violet and nephew Ivo Jeramaz, dedicated specifically to the indigenous Dalmatian grapes: Plavac Mali and Pošip. He died December 13, 2023, aged 100. Violet and Ivo still run it.

   How: Taste the standard flight (approximately €25) which includes Pošip white and Plavac Mali red, with prosciutto and cheese. Ask about Mike's philosophy: he insisted the Dalmatian grapes were as serious as anything in California or France. Ask for the story of when he first tasted Crljenak Kaštelanski — the ancient Croatian grape that IS Zinfandel. Watch the staff's face when the connection lands.

   Backup: If closed or in low season (call ahead +385 20 748 090), bottles can be purchased online from their shop at grgic-vina.com. The Plavac Mali retails for €34 at the winery.

3. 3 Hold Zinfandel's Child and Ask Six Wine Experts to Identify It Wine · Free

   Where: Matuško Winery, Potomje village — one of the largest Dingač producers, with 3,000 m² of cellars carved into the hillside. Contact: matusko@net.hr / +385 20 742 393. Walk-ins welcomed; tastings are free.

   What: Here is the DNA story most people in California don't know: Plavac Mali is NOT the ancestor of Zinfandel. In 2001, researchers from UC Davis (Carole Meredith) and Zagreb University (Edi Maletić, Ivan Pejić) found only nine surviving vines of a grape called Crljenak Kaštelanski in a garden in Kaštel Novi near Split. DNA test: perfect match with Zinfandel. Same grape. Different hemisphere. The grape traveled to America around the 1820s. While it became 'America's grape' in Sonoma and Napa, it stayed home in Croatia under its ancient name, Tribidrag — mentioned in 15th-century shipping records to Venice. Plavac Mali is what happened when Zinfandel and another local grape called Dobričić had offspring. You are drinking the child. The wine in Dingač is the child of California's most celebrated grape, grown on 45-degree limestone cliffs above the sea it has faced for centuries.

   How: Ask for the free tasting of up to 6 wines — it includes young Plavac Mali, reserve Dingač, and sometimes a dessert wine from the same grape. When tasting the Dingač, say to whoever is pouring: 'I want to understand the connection to Zinfandel.' If you know wine, notice the structural difference — Plavac Mali is denser, more savage, with higher tannin than American Zin. That's the limestone. That's the triple sun.

   Backup: If Matuško is temporarily closed, Vinarija Madirazza next door in Potomje also offers informal tastings. Almost every family in Potomje (population 209) makes wine — knock on any cellar door marked 'Vinarija.'

4. 4 Eat the Oyster That Outlasted the Dubrovnik Republic Adventure · Price: low

   Where: Mali Ston, the small fortified town at the base of Pelješac where the peninsula meets the mainland. The Mali Ston Bay waterfront has a row of seafood restaurants and open-air vendors. Drive 30-40 minutes from Potomje toward Ston along the D414.

   What: The Romans cultivated oysters in Mali Ston Bay. When Dubrovnik's Republic of Ragusa purchased the Pelješac Peninsula in 1333 for 500 Byzantine gold coins, they inherited a shellfish operation that was already ancient. In 1936, Mali Ston oysters won the Grand Prix and gold medal at the General Trades International Exhibition in London. In 2020, the European Union granted them Protected Designation of Origin status. These oysters have outlasted empires. The secret: the Neretva River flows into the bay from the north, mixing with the Adriatic. The resulting salinity and nutrient levels produce a uniquely fat, mineral, sweet oyster — the only surviving population of European flat oyster (Ostrea edulis) of this quality in the entire Adriatic.

   How: Sit at any quayside restaurant or waterfront stall in Mali Ston — Kapetanova Kuća and Bota Šare are the most well-known restaurants, but even simple waterfront stalls are excellent. Order a plate of 6–12 oysters raw, with just lemon. Ask them to bring a glass of Pošip — the white Dalmatian grape Grgić Vina makes, or any local producer. The Pošip's crisp stone-fruit acidity cuts the oyster's brine. This is the meal that has not changed in 700 years.

   Backup: If you prefer cooked shellfish, order 'buzara' — mussels in garlic, white wine, and tomato. The Mali Ston mussel season runs year-round; oysters are best September through April. Restaurants open daily from approximately May through October; reduced hours in winter — call ahead.

5. 5 Find the Triple-Sun Vineyard Where 17% Alcohol Happens Naturally Wine · Price: low

   Where: After exiting the Dingač tunnel from Potomje, walk or drive along the gravel track that runs along the cliff face above the vineyards. The track begins immediately at the tunnel exit and follows the terraced rows south toward the sea. Coordinates for the upper viewpoint: approximately 42.9178°N, 17.3698°E.

   What: These vineyards sit at 45 degrees. Stand at the top and look: beneath you is white limestone with almost no soil — just rock and rubble. The vines are head-pruned, gnarled, low to the ground, clinging to handmade stone terraces. They're getting light from three angles simultaneously: direct sun from above, reflected light from the Adriatic surface below, and reflected light bouncing off the white limestone rock under their roots. On summer days the temperature on the vineyard surface reaches 65°C (150°F). No irrigation. 2,800 hours of sunshine per year. The result: Plavac Mali here routinely reaches 15–17% natural alcohol without any addition. Winemakers talk about 'restoring' balance rather than building it. The wine is made in the vineyard — the cellar is almost a formality.

   How: Walk slowly down into the first few rows of terraces. The stone walls were built by hand over centuries — you are walking on the same terraces the donkeys navigated before 1975. Taste a grape if it's harvest season (late September–October). Ask any winemaker in Potomje when they pick — they'll tell you they wait until almost everyone else has already harvested because this site runs weeks later than anywhere else on the peninsula.

   Backup: If the vineyard track is blocked or unclear, the view from directly above the tunnel exit gives a near-identical panorama. In winter or early spring the vines look skeletal — just gnarled black wood on white rock. This is also extraordinary.
