Pub chain JD Wetherspoon has said it will replace champagne with sparking wines from the UK from next month.
The company’s founder, Tim Martin, who campaigned for Brexit, said it was part of a transition away from products made in the European Union.
Under the plan, British wheat beer and alcohol-free beer will replace the current beers brewed in Germany.
Mr Martin said the new drinks would be cheaper than the European Union products that they are replacing.
“This move helps us to broaden our horizons so that we create an improved offer for the two million customers who visit our pubs each week,” he said.
“It is the start of a review all products in the next six to 24 months, with the object of making our business more competitive.”
Mr Martin called the EU customs union “a protectionist system which is widely misunderstood”.
“It imposes tariffs on the 93% of the world that is not in the EU, keeping prices high for UK consumers.
“Tariffs are imposed on wine from Australia, New Zealand and the US, and also on coffee, oranges, rice and more than 12,000 other products,” he said.
Wetherspoon will replace champagne with sparkling wines from the UK, such as from the Denbies vineyard, and Hardys Sparkling Pinot Chardonnay from Australia.
Its UK wheat beers will include Blue Moon Belgian White, Thornbridge Versa Weisse Beer and SA Brains Atlantic White.
Wetherspoon will continue to serve Kopparberg cider from Sweden, as the company has said it will transfer production to the UK post-Brexit.
