"This looks horrible from our perspective. We don't like it one bit," says Rex Stults, vice-president of industry relations at Napa Valley Vintners, which represents 540 wineries in the sunny slopes of California's most famous wine region."Wine is an international product. Even here in the Napa Valley, our wineries primarily get their corks from Portugal, and their oak barrels, a key component in winemaking, from France.

Mr Stults adds: "They're already expensive and the potential is that they will get more expensive."Also, trade wars cut both ways. He says the tariffs announced against Canada are having a devastating impact on US wine exports."Canada is the most important export market for California wines, and one of the top export markets for Napa Valley wines. Right now, there are zero Napa Valley wines on the shelves of stores in Canada.

"They've removed all American alcohol beverage products from their store shelves!"Mr Stults adds: "We just want to compete on an even playing field with our friends and neighbours all over the world. That's our ask and that's our hope."

The US Court of International Trade on Wednesday struck down President Donald Trump's tariffs imposed under the 1977 International Emergency Economic Powers Act (IEEPA).

The court ruled IEEPA did not give the president the authority to impose certain tariffs.On the other side of the ledger, the tariffs on metals and car parts - which are unaffected by this ruling - brought in around $3.3bn (£2.4bn), based on rounded figures.

And the biggest source of tariff revenue for the US in the period was from tariffs imposed on China dating back to Trump's first term in office, which raised $23.4bn (£17.3bn). These are also not affected by the court ruling, as they were not justified by IEEPA.However, this is a backward looking picture - and the new tariffs were expected to raise considerably more revenue over a full financial year.

Analysts at the investment bank Goldman Sachs have estimated that the tariffs the trade court has struck down were likely to have raisedIn terms of the overall impact on Donald Trump's tariff agenda, the consultancy Capital Economics estimates the court ruling would reduce the US's average external tariff this year from 15% to 6.5%.
