PLB will take on UK take-home distribution of Hungarian wines from Hilltop Neszmély on August 1. Its sister company Bibendum already handles the wines in the on-trade.
PLB will handle all the business that Hilltop currently does with M&S, Waitrose, Morrisons, Asda and the Co-operative for exclusive and own-label wines in addition to Hilltop branded ranges.
Paul Meihuizen, buyer for the Bibendum PLB Group, said: "The Hilltop wines are a great addition to PLB's Hungarian portfolio.
"Hilltop produces wines from both indigenous and international grape varieties and has a house style that appeals to the UK palate.
"The Hilltop philosophy requires that each wine delivers superb purity of flavour and the classic character of the grape from which it is made and this results in wines that are very popular with the UK wine drinking consumer."
PLB managing director John Osborne added: "Hilltop already has a strong customer base across the UK off-trade which we are looking forward to building on.
"Adding the Hilltop range to our already strong Hungarian offering will help position PLB as the go-to supplier for Hungarian wine.
"Hungarian wines have been growing in popularity in the UK due to refreshing, fruity flavour profiles and reasonable price tags, so expanding our range of wines will allow us to meet increasing demand."
The Hilltop winery is on a hill overlooking the Danube and was founded in 1990 by Éva Keresztury, Imre Török, Judit Storcz and Ákos Kamocsay, who still manage the estate today.
It claims to be the largest Hungarian producer of bottled wine for export to the UK.
