Organic chocolate company Seed & Bean has signed a deal to be the official chocolate supplier to the Glastonbury Festival.

As part of the four-year partnership, the ethically accredited brand has launched two new flavours – milk chocolate with sea salt & lime and white chocolate with raspberry & vanilla – which will be available to festival goers alongside the brand’s existing dark chocolate with hazelnuts variant.

“It’s great for us to be acknowledged and actively supported by the biggest and best festival in the world,” said company founder Stephen Rudkin. “It shows that being sustainable and ethical can reap huge rewards, as long as you are also unique, delicious and affordable,” he said.

The limited-edition Glastonbury bars come in specially designed retro wrappers by artist Matthew Lyons and carry the Fairtrade and Soil Association logos.
