The latest innovation will be launching in 50cl bottles in from multiples throughout Cornwall and the South West.
The 4% abv cider is made by blending original Cornish Rattler with red berries, which the company describes as a “fresh summery drink which still retains the Rattler bite”.
Sam Healey said: “We like to be different, and Berry Rattler is no exception. It offers a more unusual blend, a distinctive label and branding which will ensure standout from the crowd.”
Healey added there were plans to introduce the brand to consumers across the south.
Cornish Ratter Cyder (6% abv) was bottled in 2007 and Pear Rattler Cyder (4% abv) was introduced in 2008.
