Freixenet Copestick has said it has been “overwhelmed” by the positive response from its fans about its I Heart Superheroes competition, and it is now ready to extend the concept further.

The company initially teamed up with Intervino to producer 2,500 bottles of personalised I heart Superheroes Prosecco.

It asked consumers to nominate their own chosen superheroes with suggested examples including “local posties, shop workers, NHS workers and delivery drivers”.

The campaign launched on April 6 on the brand’s Facebook and Instagram pages and the company aimed to select daily winners at random over a two-week period.

The producer said it had 1,300 nominations just on the first day and since the launch date the response has been overwhelming, which led to plans to extend the initiative.

Danielle McDonald, brand manager, said: “We have had some fantastic stories that consumers continue to share. We have been asked many times if the bottles will be available to buy so I am pleased to say that we have listened to the brilliant feedback and created a limited edition run of 100,000 bottles.”

The bottles will be available to buy in selected Sainsbury’s and Tesco stores from this month.
