A packaging revamp for the Nando's range of sauces is putting increased emphasis on the products' signature Peri-Peri kick - a blend of lemon, spices, garlic and African bird's eye chillies.

Hitting the shelves next month, the new look also includes an on-pack 'Peri-ometer' device to indicate the products' heat level.

Ben Johnson, marketing director, said packaging was critical to communicate Nando's point of difference clearly. "Nando's consumers buy our products because of Peri-Peri," he added. "We are expecting a bumper summer this year because the weather is predicted to be hot and occasions such as the World Cup are likely to see an increase in barbecuing."

Nando's has also launched a medium-hot Sweet & Sticky Marinade - a combination of brown sugar, molasses and soy sauce with a Peri-Peri kick - as well as Perinaise (Peri-Peri with mayonnaise) and Peri-Peri Salsa spicy dips, which come with an rsp of £1.39.
