Despite being wine novices, she and her father decided to buy the business in 2009, bringing on board promising winemaker Mitja Herga.

"We agreed that we would like to produce fresh, fruity and mineral white wines," Puklavec said.

The move paid off: P&F wines now make up nine percent of the national production. Last year, the company was voted Slovenia's Winery of the Year, beating more than 170 other producers.

But for now, P&F remains part of only a handful of Slovenian wineries large and successful enough to sell overseas.

A majority of producers own less than one hectare of land, and the country still only exports around 10 percent of its wines.

There is still plenty of room to grow, Puklavec said.

"It is our mission to continue what my granddad started: to make the best possible wine and share it with the world."
