It's named after Cornwall's only native snake, the adder — a nod to the cider's sharp bite — and it's brewed with a variety of apple actually called the Rattler apple.
Rattler is a cloudy, medium-dry Cornish cider with a tangy green-apple bite and a smooth finish, pressed from apples grown on the farm's own orchards. It's served ice-cold, straight from the bottle, at Cornish pubs and seaside food stalls alike.
