Customers at Canterbury two Wetherspoons will notice that the pub chain is ditching European drinks in favour of those produced in the UK and outside the EU.
Changes include Australian wine replacing French varieties at the Thomas Ingoldsby in Burgate and the Westgate Inn at North Lane.
And in a boost to UK brewers, beers such as Suffolk-brewed Adnams will be sold instead of the German-made Erdinger.
The changes will apply across all 800 outlets of Wetherspoons, whose chairman and founder Tim Martin is an ardent Brexiteer.
He said: “This move helps us to broaden our horizons so we create an improved offer for the two million customers who visit our pubs each week.”
Mr Martin argues that the changes will lower prices in his pubs.
“The EU’s customs union is a protectionist system which is widely misunderstood,” he added.
“It imposes tariffs on the 93% of the world 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.”
But Mr Martin said Wetherspoons will continue to sell Kopparberg cider after the Swedish company confirmed it will be producing its drinks in the UK after Britain leaves the European Union.
Wetherspoons is one of the few retailers to have bucked the recent trend for poor performances in High Street and pub retail. The company is continuing to open pubs across the UK.
Last month it completed the £2.5 million refurbishment of the Thomas Ingoldsby.
It was closed for five months as a new hotel was created on the second floor and a bar and kitchen installed on the first floor.
