John Mills, managing director of Gaymer's, said the new design gave the brand a more contemporary feel, but its heritage had also been kept in mind.
He said: "It was important that this heritage and quality was maintained in the design, which can be seen through the continued use of the brand colours and William Gaymer's signature. This had to be balanced with a more contemporary edge, which is evident in the redesigned packaging."
The company has also brought the abv of Olde English's bottled cider in line with its draught product, lowering it to 4.5 per cent from 5.3 per cent.
The investment is part of £26 million Gaymer's has pledged to spend on its cider brands this year.
