MILAN (AP) — European producers of premium specialty agricultural products like French wine, Italian Parmesan and Spanish olives are facing a U.S. tariff hike due Friday with a mix of trepidation and indignation at being dragged into a trade war they feel they have little to do with.

The tariffs on $7.5 billion on a range of European goods were approved by the World Trade Organization as compensation for illegal EU subsidies to plane maker Airbus.

The U.S. has some leeway in deciding what goods it puts tariffs on. So while it is taxing European aircraft goods an extra 10%, it is walloping agricultural products an extra 25%.

"It's a nightmare," says Aurélie Bertin, who runs the 700-year-old winery Chateau Sainte-Roseline in southern France. "We don't know what will be the result."
