The U.S. is suddenly looking less bubbly for European wines. President Donald Trump on Thursday threatened a 200% tariff on European wine, Champagne and spirits if the European Union goes forward with a planned 50% tariff on American whiskey.

It is these U.S. businesses that have to pay the levies, said Aneff, also managing partner of Tribeca Wine Merchants, a wine store in New York, adding American retailers and restaurants would also suffer if suppliers hike prices to cover the costs.

Industry representatives warned that a 200 percent tax on European wines and spirits would halt shipments to the United States and wipe €4 billion off France’s trade balance.
