The move follows a deal with Zywiec’s brand owner, Grupa Zywiec, part of the Heineken Group.
Zywiec, Poland’s top premium lager, has previously been solely distributed in the UK by Brand Distribution & Development.
Jonathan Townsend, speciality brands director of S&N UK, said: "We are delighted to welcome Zywiec beer as the latest addition to our premium lager portfolio.
"It is already widely regarded as the best and most premium of all Polish beers and represents an exciting opportunity for our business.
"There are over a million Poles currently residing in the UK who are estimated to consume over a million hectolitres of beer per annum.
"Whilst we recognise that this is a relatively transient target market, which will change in size as some of these Polish nationals decide to return home, there is absolutely no doubt that we will be able to significantly grow the brand in the UK."
Zywiec joins an S&N line-up of imported beers which includes Singapore’s Tiger beer, Italy’s Birra Morretti, Austria’s Edelweiss and Portugal’s Sagres.
