Wetherspoon chairman Tim Martin, an ardent supporter of Brexit, said: "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".
Martin is skewing his pubs' ordering of drinks away from European Union sources, because it's cheaper to buy them from outside the European Union and British beers and wines can be purchased without paying the tariffs imposed by the EU's "protectionist system".
Mr Martin called the EU customs union "a protectionist system which is widely misunderstood".
He said that he intends to find a replacement for prosecco from the United Kingdom or new world countries which include Argentina, Australia, Chile, New Zealand, South Africa and the US.
