The £1.50 bottle is “ideal for sharing” and the long-life formulation has a nine month shelf life, making the bottle a “strong addition” to a store cupboard or pantry.
Yazoo said its one-litre milk drinks are currently growing ahead of the market rate at 17% year on year.
Kate Allison, Yazoo marketing manager at brand owner FrieslandCampina UK, said: “Our new limited edition flavour has proved very popular with shoppers so far, with sales now worth over £46,000 and growing in just six weeks since launch.
“Jaffalicious Choc-Orange offers an exciting variant for existing fans and creates a sense of exclusivity, which in the long term contributes to brand longevity.
“It also entices new shoppers to the category, with 7% of non-flavoured milk drinkers saying it would prompt them to buy Yazoo.
“Our one litre formats are permanently available in our best-selling core flavours: Chocolate, Strawberry and Banana, and as we respond to the growing demand for take-home drinks and treats – we are very excited to be extending this to our limited-edition range to provide Yazoo lovers with more variety.”
