But in a potential boost to United Kingdom brewers and vineyards, all 880 pubs - affectionately known as Spoons - will sell British sparkling wines and wheat beers instead.
"UK consumers have clearly voted it [champagne] its sparkling wine of choice, making the United Kingdom the leading export market for champagne", Mr Peretti said.
The changes - which will come in from July 9 - will also see sparkling wine from Australia replace French champagne.
Alcohol-free Adnams Ghost Ship will replace Erdinger alcohol free beer from Germany.
Founder and vocal Brexit supporter Tim Martin said that the move to non-EU suppliers would help to make prices lower in the long run, if the United Kingdom ends tariffs once it has left the customs union.
Others were quick to point out that Martin's statement made no mention of Prosecco, which is routinely advertised in the pub's food and drink offers and is more widely drunk across the United Kingdom than any other sparkling wine.
Martin - a vocal eurosceptic - said the pub chain is reviewing all of its products in a company-wise reshuffle which could take up to two years, something he hopes will make the business "more competitive".
The drinks boss said it makes sense to invest in United Kingdom drinks products now because of the EU's "protectionist" tariff systems, which he claims are "widely misunderstood".
Mr Martin hinted that post-Brexit Wetherspoon's drinks may be cheaper.
"Tariffs are imposed on wine from Australia, New Zealand and the United States, and also on coffee, oranges, rice and more than 12,000 other products".
'However, we are starting to make the transition to non-EU trade now'.
And from this summer Wetherpoon's 880 pubs will serve wheat beers such as Blue Moon Belgian White - which is produced in the US - Thornbridge Versa Weisse Beer and SA Brains Atlantic White, both of which are British-brewed.
Swedish cider Kopparberg makes it past the cull, due to the company's decision to make its cider in United Kingdom after Brexit.
I've never personally bought Champagne in Wetherspoons and probably never will now as Moët & Chandon champagne is being swapped with sparkling wines from the United Kingdom and Australia.
Wetherspoon's will continue to serve Kopparberg cider from Sweden.
Mr Martin said the new drinks would be cheaper than the European Union products that they are replacing.
