The first berries of the season, the Duke variety, have been harvested in Belgium and sold locally, marking the start of the local berry season which is expected to run until early November. The season's start in the Netherlands is anticipated to be late June or early July due to a slower maturation process caused by a harsh spring. The annual harvest of blueberries in the Netherlands is approximately 8 to 9 million kilos, and consumption has doubled in the past five years, reaching about 900 grams per capita annually. The Netherlands is the primary supplier of blueberries to both Germany and Belgium.
