NEGRAR, Italy, July 28 (Reuters) - Italy's wine

producers, already struggling amid a slowing economy and a

strengthening euro, face a further challenge after wine and

spirits were left out of the U.S.-EU trade deal agreed on

Sunday.

Discussions are continuing regarding any tariff exemptions

for the wines and spirits sectors in the framework trade deal, a

senior European Commission official said on Monday, a day after

the U.S. and EU agreed a 15% tariff on U.S. imports of most

other goods from the European Union.

Producers in the winemaking region of Valpolicella, in

northern Italy, warn that on the top of any new tariff, their

exports will be impacted by the depreciating dollar, which has

lost more than 12% against the euro this year, making European

goods more expensive for U.S. consumers.

"This is already pretty bad," said Andrea Sartori of the

Sartori winery in Negrar di Valpolicella, founded in 1898.

"I'm very worried about the economy overall. And we all know

that wine consumption doesn't thrive very well when we have seen

economic crises in the past," Sartori told Reuters. "So this

could be a domino effect that could hit the wine trade as well."

The United States is the biggest export market for Italy's

wine and spirits producers, generating sales of 2 billion euros

($2.3 billion) last year, or a quarter of their global sales,

according to industry group Federvini.

Lamberto Frescobaldi, president of Italian wine producer

association UIV, said on Sunday that 15% tariffs on wine would

result in a loss of 317 million euros ($372.63 million) over the

next 12 months.

Wine producers are already facing subdued domestic demand,

with the Italian economy forecast to grow just 0.6% this year,

according to national statistics bureau ISTAT, although premium

wines are set to do better as deeper-pocketed consumers are less

price sensitive.

They include Valpolicella's top end Amarone wine.

"Amarone is the least sensitive because it's already a

premium wine with a pretty high price. So I don't think it would

be a dramatic change," Sartori said.

"I'm more worried about Valpolicella and Ripasso, which are

mainstream, and a price increase could possibly damage the

sales," he added
