The pro-Brexit founder of Wetherspoons announced the pub chain will ditch EU-produced champagne and wheat beers to make way for British and Australian drinks.
Mr Martin argued leaving the European Union would give British businesses to expand to more global drinks market without having to worry about customs union tariffs.
Speaking to Sky News, he said: "I don’t think the customers will think it’s too harsh if we can get equivalent or superior products perhaps at a significantly better price.
"In the event of Brexit when things are changing, it’s a very good opportunity to look around the world and see what we can get that enhance customers’ enjoyment of our pubs."

Moet & Chandon champagne will be replaced with sparkling wine from the UK, like Denbies Sparkling Whitedowns Brut, Whitedowns Rose Brut and Australia’s Hardys Sparkling Pinot Chardonnay.
Mr Martin also suggested Brexit would free the UK from the EU "stranglehold" over superior drinks such as French champagne and sparkling wine.
