Willamette Valley Vineyards founder Jim Bernau said uncertainty caused by Trump’s tariffs is making consumers spend less and has destabilized the U.S. wine industry.

The European tariff was expected to be put into place beginning April 1 as a response to U.S. tariffs on steel and aluminum.

Imported wine and spirits encompass 35% of revenue of all US sales in the alcohol market, meaning that all aspects of cocktails and wines ordered at restaurants or purchased at retailers will “rise significantly” if the tariffs go into effect.
