A low-calorie soft drink produced by a traditional Japanese infusion process has been launched by Future Drinks.

Koji, available in the on-trade now in lemon & ginger and mandarin & cranberry, will launch in the off-trade early next year. It is being manufactured by cider producer Brothers Drinks.

Positioned as a healthy adult soft drink, Koji is free from additives and has 49 calories per 330ml bottle. Future plans more flavours next year.
