A British father and son are being sued by the Italian state body over claims of 'misusing the Prosecco name' and selling 'fake fizz'.

The Consortium for the Protection of Controlled Designation of Origin Prosecco (Consorzio), which exists to guard the Prosecco name, claim the wine entrepreneurs Michael Goldstein and his father, Ralph, mislabelled a non-genuine product as Prosecco and exploited the protected Prosecco name. 

The father and son, who are said to be the driving force behind drinks importer Prosecco International Ltd and its flagship sparkling wine Bella Principessa, are fighting the claim.

They deny any infringement and insist their white and rose Bella Principessa sparkling wines 'conform to the Prosecco specification'.

Despite saying that their evidence that the wines meet the specification of Prosecco 'seems persuasive,' Judge Richard Hacon has now ordered a full High Court trial.

The Consortium - whose official Italian name is the Consorzio Di Tutela Della Denominazione Di Origine Controlla Prosecco - is suing the pair and the company, over a 'long list of acts which are said to constitute an infringement of Consorzio's rights under the regulation', said the judge. 

Prosecco was first officially recognised by the Italian government as a distinct wine restricted to specific areas of north-eastern Italy in 2009, resulting in the Consorzio making stringent efforts to ensure retailers do not abuse or infringe its name.

Judge Hacon said: 'As is widely known, Prosecco is the name given to certain wines produced in the northeast of Italy. 

'The Prosecco protected designation of origin is protected in this country under EU Regulations, now assimilated into UK law.' 

Prosecco International, which was set up in 2018, is a London-based company engaged in a variety of alcohol production and distribution, including 'distilling, rectifying and blending spirits, manufacturing wine from grape and other business support activities', said the judge.

Michael was a director of the company between 2018 and 2024, while his father, Ralph, is currently a director.

The action focuses on allegations of infringement of European regulations and of the PROSECCO certification mark, a type of UK trade mark, on two websites operating under the domain names Prosecco.com and Proseccodoc.com, which 'target the UK' by using the Prosecco name, Consorzio claims.

'The particulars of the claim cite the use of PROSECCO in association with and on bottles of sparkling wine called Bella Principessa,' the judge said.

The judge added: 'Consorzio does not accept that the Bella Principessa and Prosecco Rosé wines conform to the Protected Designation of Origin (PDO) specification'.

The Goldsteins and the company, however, insist that both wines do pass the test to be designated Prosecco, pointing to evidence of which the judge said, 'on its face...seems persuasive.'

In online advertising copy for the Bella Principessa brand, Michael Goldstein says: 'We couldn't find a Prosecco that tasted exceptional, looked beautiful and felt meaningful enough to share with the people who matter most, so we made one - Bella Principessa. 

'The Prosecco guests are proud to ask for by name. It comes in two expressions: Rosé and Brut. Always in good taste.'

The wine is described as being 'crafted in the sunlit hills of northeastern Italy's Veneto region in partnership with a fourth-generation winery'.

'Bella Principessa is a premium Italian Prosecco produced under Italian Prosecco DOC standards. Each ceramic-painted bottle, adorned with Italian floral artwork and the Bella Principessa butterfly, is as striking on the table as the wine is in the glass,' the advert states.

Ruling this week on a bid by the Goldsteins and the company to strike out the claim against them, the judge said: 'Michael and Ralph Goldstein are alleged either to have had, or to have, significant control over the acts of Prosecco International of which complaint is made.'

In denying infringement, Prosecco UK and the pair maintained, amongst other defences, that Consorzio was suing the wrong target, as the real owner of the offending website domain names is a US drinks company.

He noted that the defendants admit that drinks which are not Prosecco wines, including vodka and wine in a can, featured 'on an older version of the two websites in issue, although they say none of those drinks were sold.'

'They contend that this did not amount to an infringement of any rights held by the Consorzio and in any event the appearance of the non-Prosecco drinks on the two websites has now ceased,' he continued.

'They say the websites now only feature the Bella Principessa wine and a Prosecco Rosé wine, both of which conform to the PDO Prosecco specification.

'In particular, the Bella Principessa wine belongs to a subcategory of Prosecco wines designated Prosecco DOC wines which all are, by definition, Prosecco DOC wines.

'The defendants' case is that the Bella Principessa and Prosecco Rosé wines are genuine PDO Prosecco wines.

'The Consorzio does not accept that the Bella Principessa and Prosecco Rosé wines conform to the PDO specification.'

Dismissing the application brought by the defendants, the judge said the evidence put forward to support the defence that the two wines conform to Prosecco specifications had been filed late and that it would have to go forward and be considered in a full trial.

He continued: 'I do not accept that I can assume on the evidence now available before the court that the damage caused to the Consorzio as a consequence of the admitted use of the sign PROSECCO in the past has been negligible.

'This may be a matter for evidence at the trial, dependent upon which the trial judge may or may not grant an inquiry as to damages or an account of profits.

'However, on the evidence available to the court now, it may be that the damage was significant.

'I take the view that the defendants have not shown that the Consorzio has no prospect of succeeding in its claims for infringement of the Regulation and Certification Mark.'

He added: 'The question whether the content of the websites in issue constitutes infringement of the Regulation and the Certification Mark must be resolved at trial.'
