Kepeš's winning cocktail Lolita was made with Bacardi Gold rum, Mozart chocolate liqueur, vanilla liqueur, Finest Call Pina Colada liqueur and caramel syrup, topped with semi-whipped cream.

She competed against 500 other bartenders from 63 member states of the International Bartenders Association (IBA), which annually organises the WCC.

Kepeš was the first female bartender to represent Slovenia in the Classic Mixing Competitions, which comprise six categories: Before Dinner Cocktail, Sparkling Cocktail, Short Drink, Long Drink, Bartenders Choice and After Dinner Cocktail.

The WCC also includes the Flairtending Competition, in which bartenders entertain their guests by preparing cocktails using dazzling tricks.

Kepeš is the head of Ljubljana's cafe and bakery Lolita and has been regularly participating in bartending competitions as part of the Slovenian Bartender Society.
