A glass bottle shortage is likely to push up the price of wine, a report has found. Wine industry experts issued the warning after glass suppliers reported steep increases in costs caused by shortages.The Grocer said wine prices were on course to surge after suppliers said they faced “dire” cost increases.According to industry sources, demand for bottles – particularly green bottles – had outpaced supply which in turn had sent cost prices rocketing.A senior source said they had been warned that price increases were coming before Christmas, but that actual increases had been far higher than expected. “The question for us is not even price but getting hold of the stuff – we have been told that some manufacturers may not even supply us because they are moving into proprietary bottles and spirits,” they said. Andy Sagar, managing director of Kingsland Drinks, said it had a faced “double digit” increase.He told The Grocer: “For the first time in over 20 years suppliers are advising that they cannot accommodate new business, and in some cases want to reduce their commitment.Capacity is also tight in mainland Europe and the weak pound means that glass is more expensive to import even when it is available.”A spokesman for British Glass, which represents the UK industry, said bottle manufacturers were “investing hundreds of millions of pounds in new furnace capacity.However, due to the length of furnace life, often 25 years, it is a slow process”.
