Rockware Glass have produced a new 750ml water bottle for Highland Spring. The bottle is an addition to the existing range of 330ml & 1 litre bottle options & contains the same pure & natural Highland Spring water. Research shows consumers dining in high quality restaurants are 30% more likely to drink sparkling water than the average adult. NOP research also suggests 51% of UK adults who drink wine in a restaurant or hotel prefer to drink it with bottled water. The bottled water market in the on-trade sector is growing by a healthy 8%. Sparkling water is extremely popular in this sector. Sally Stanley, marketing director of Highland Spring said: 'The new 750ml bottle is a great addition to our on-trade glass portfolio. With our current position as the UK's No 1 sparkling & No 3 still brand, we are certain this will be another winning option for the on-trade.'
