British wine drinkers may face paying more for a glass of New Zealand sauvignon blanc.
A smaller harvest has put supplies to UK outlets under strain, hospitality supplier Beacon said.
Beacon drinks buyer Mark Holness said the reduced harvest would mean a favourite drink would be harder to come by and more expensive to buy.
"There is concern that supplies of New Zealand Sauvignon Blanc are also under strain following the poor harvest and we are working with our contacts and suppliers to identify the full extent of the problems," he said.
"In recent years growers have also been moving away from the popular Marlborough region in New Zealand and so British drinkers might also notice a change in taste profile of the wine, which is something they may not be aware of yet."
