Wines from the sunny hillsides of Crimea have been popular with Russians since the time of Czar Nicholas II – and now some vineyard owners are hoping their new union with Moscow could boost business despite the winds of war.
French actor Gerard Depardieu is among those reportedly to have invested in Crimean vineyards but most of its 25,000 hectares (61,780 acres) are owned by small businessmen like Pavlo Shvets of Uppa Winery, southeast of Sevastopol.
"I think for business, for wine production, selling wine directly to Russian buyers would be a lot better," says Shvets.
"The Russian market is a lot bigger, richer and is developing faster than the Ukrainian one. That's a fact."
Agriculture is one of Crimea's biggest earners, making up 10 percent of gross regional product, and grape growing accounts for 10 percent of that, mainly in the south.
But Ukraine's economy is fragile – its new government says it needs $15 billion to stabilize and restructure while analysts warn it could be set for a debt default.
Many people who voted for closer ties to Moscow in Sunday's referendum cite the economy as a major motivator.
Russian Market Beckons For Crimea Producers
Shvets, a sommelier in Moscow for 15 years before buying his ten-and-a-half hectare vineyard, employs 12 people and produces around 30,000 bottles a year.
He sells half his production in Ukraine and exports the other half to Russia but hopes this could increase in future.
"If you talk only about market and about business, I think for my business it will be better if Crimea will become part of Russia," he adds.
Conditions for doing business under Russia could also be better than they are now, he said.
He is frustrated that a licence to sell alcohol in Ukraine costs 50,000 euros ($69,100) a year and says that the Russian government gives incentives to small growers.
Shvets's vineyard is accessible only by a dirt track so steep that the vineyard's van stalls repeatedly on the way up.
Overlooking the valley below as spring sunshine beats down, foreman Aleksiy Apetsko explains that the culture of drinking wine rather than vodka was bigger in Russia than in Ukraine.
"Maybe it is when people have more money and start to travel more they start to be more interested," he adds.
The vineyard is looking to create a tasting area in the hope of attracting some of the tourists who make up Crimea's other main source of revenue.
At the Inkerman winery just outside Sevastopol, which sells 60 percent of its wine in Ukraine and exports 20 percent to Russia, head of production Larissa Shymchok is more diplomatic.
"We don't do politics, our wine is drunk in Russia and in Ukraine and we hope that it will be drunk in France one day," she says.
Inkerman is one of Crimea's biggest and most popular wines, with up to 36 million bottles sold per year.
"We're a bit worried for our vineyard. We are peaceful people, our profession is about passion and we hope that everything will be good in Crimea and in Ukraine," she adds.
Famed for its beaches, temperate climate and historic towns like Sevastopol, home of Russia's Black Sea Fleet, Crimea draws thousands of tourists per year, with around 60 percent from Ukraine and 20 percent from Russia.
Some tour operators are fearful of the impact from the tensions, with a knock-on effect for vineyards.
"Lots of tour companies have cancelled their trips to Crimea, to Ukraine in general because of the conflict which everyone is concerned about," says Lilia Ivanova of Intourist, the former Soviet state tour agency which is still a major player in the market.
Despite the valuable boost which closer ties with Russia could bring to winemaking, Shvets shares this ambivalence about the current situation.
"People here are afraid of war," he says. "I think only time will show us which possibility is better."
