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.

President Trump on Thursday threatened to impose tariffs on wines, Champagnes and other alcoholic products imported to the U.S. from France and other European countries in response to raised tariffs the European Union placed on American whiskey.

President Trump’s threat to impose 200 percent fees on European wines could harm importers, distributors, retailers and restaurants without necessarily helping U.S. producers.
