VinItaly is the largest Italian wine fair in the world, with more than 4,000 exhibitors spread over almost 90,000 square meters and tens of thousands of buyers, sellers and importers.
At this year's meetup in Verona, the wine chatter turned to fears that the future doesn't look so "rose" for some wineries.
The UK's decision to exit the EU was a path few European wine producers wanted. The UK is a massive importer of European wines and champagne, spending US$2.76 billion imports in 2016. Indeed, only the US imports more European wines.
"We are all very worried," Cesare Cecchi, the chairman of one of the Cecchi winery, one of Italy's largest and most famous wine dynasties, told AFP.
Fears have already been stoked by foreign Secretary Boris Johnson, who, on an official visit to Italy in September 2016, warned the country to ensure a fair free-trade deal for the UK, or have Italian Prosecco producers face restricted export access to the UK.
"No one would want to see any tariffs on Prosecco from Italy. We are the biggest drinkers of Italian wine in Europe. No one would want to see any tariffs on Italian wine any more, I think, than the Italian government would want to see any detriment to the interests of the City of London," Johnson said.
The industry reacted with nervous jitters. Prosecco is hugely popular in the Brits, who drank around 300 liters of the stuff in 2016. Some in the UK even refer to the end of the work day as "Prosecco o-clock."
However, some wine experts have suggested that the UK's voracious appetite for wine together with the uncertainty for European producers over the next two years could open up huge opportunities for growing English producers.
Although not perhaps synonymous with quality wine or champagne, England has had a couple of record award winning vintages over the last few years.
In 2016, a blind test by a prestigious competition in Paris judged an English sparkling wine on top of a traditional French champagne, much to the delight of the British wine industry.
According to the UK's Wine and Spirit Association (WSTA), the UK produces five million bottles a year.
With gaps in the market likely to appear amid the Brexit transition period, that number is expected to be boosted significantly to more than 10 million bottles by 2020.
"English wine is a fast growing industry with bold ambitions to boost production and open up new export opportunities. It is on the way to emulating the global and long standing success of Champagne," WSTA chief executive Miles Beale said.
English wines are currently being exported to the rest of Europe, China and the US.
