Juice maker The Berry Company is bringing the latest batch of 'superfruits' to the retailer aisles this autumn by including them in two new drinks.

The drinks will be made from the juice of goji and acai berries, which are being heralded as two of the most nutrient-dense fruits on earth. They are likely to be launched in September.

The goji berry is a raisin-like fruit described as a cross between a cherry and a cranberry, and contains 500 times more vitamin C than oranges, according to The Berry Company. It is also one of the richest known sources of the antioxidant beta-carotene.

Acai fruit, meanwhile, is already causing a stir in California because of its health benefits. It contains high levels of iron and calcium as well as more than twice the antioxidants found in blueberries.

The Berry Company founder Khaled Yafi said that both acai and goji fruit had the potential to become the next pomegranate and were already creating interest in the UK.

"As a producer of berry drinks, we are well placed to tap into the health properties of these fruits," he said.

The first bottled juice version of the acai fruit, called Happy Monkey, is expected to be available in Waitrose stores throughout the UK from next month.
