The wild blueberry

(Vaccinium myrtillus) 

Blueberries have been part of our daily diet since time immemorial. We have known since Hildegard von Bingen (1098-1179) that the small dark fruits not only taste good, but also have a well-deserved place in scientific literature. Her writings influenced entire generations of doctors, naturalists and scholars.

And modern science today confirms that our ancestors were quite right. The small berries contain bioactive substances such as anthocyanins, flavonoids and antioxidants with great nutritional value for the human body.

Late summer berries with rich colors

Botanically speaking, blueberries belong to the heather family (Ericaceae). In fact, its bushes only grow to a height of around half a meter and are considered to be very robust, especially when it comes to frost.

The berries themselves have a diameter of 6 to 10 millimetres and are dark blue to purple in color. Like other dark berries, the wild blueberry ripens late. The fruits contain a whole summer’s worth of sunshine. This allows the valuable secondary plant substances in the fruit to develop optimally. The riper the fruit, the more relevant anthocyanins and antioxidants it contains.
