Worldwide supplies of Prosecco are at risk because of poor harvests.
Last year sales of Prosecco overtook Champagne in the UK for the first time ever, with more than £180m spent on the Italian sparkling wine and a mere £140m going on Champagne.
But industry experts are warning that the drink’s popularity has led to rapid planting, causing many failed harvests.
Roberto Cremonese, export manager at Bisol, said: “Last year’s harvest was very poor, and down by up to 50 per cent in some parts, so there is a very real possibility of a global shortage.
“We’ll find out how big the problem is in August when the brokers release their stock. At the moment we don’t know how much Prosecco they’re holding on to.”
Any shortage is expected to hit the cheaper end of the market, with Prosecco under £6 potentially becoming a thing of the past.
Last week’s London Wine Fair saw the launch of several Prosecco substitutes. Sparkling white wines from Spain and Australia have been developed in order to target the UK consumer who is missing the bubbles.
