American blueberry, which is larger and with less flavour than the northern European varieties, particularly those from Nordic countries. The American blueberry is available commercially and is a cultivated berry for the market. The berries of Nordic countries are harvested 'wild' or in managed woodlands but still from wild stock plants. If Nordic berries are available, they will be labelled as Scandinavian or wild or Swedish blueberries and will be worth paying the extra money for. As with many berries, the hours of exposure to light, rather than warmth, are what informs the intensity of the flavour.
