Tetley tea will work with brand design consultancy CHILLI UK to launch a new premium blend of tea.
Packaging will be designed by the consultancy for the Tetley Estate selection, created by handpicked leaves from tea estates in the foothills of Mount Kenya. The high altitude of the chosen leaves is said to give the tea "sparkle" and intense flavour.
Managing director of CHILLI UK, David Whittle, said: "It's been fantastic to work with such a great brand as Tetley on a brand new product launch."
The product will begin reaching shelves by mid-February.
Senior brand manager at Tetley, Michelle Colley, added: "With out new Estate Selection blend, consumers can be confident of upgrading to a great tasting tea, but without adding too much on to the price tag."
