Is this product a pure juice or a nectar, and what's the difference?

The SEMU Astelpaju-mustika nektar is a nectar, not a pure juice. In EU food standards, the main difference lies in fruit content and permitted ingredients. Pure fruit juice is typically 100% fruit from pressing, with no added ingredients except possibly allowed processing aids. A nectar is a fruit-based beverage that contains a defined minimum percentage of fruit juice or purée, which is diluted with water and often has sweeteners added to balance the natural tartness of certain fruits. For many berries, especially tart ones like sea buckthorn, a nectar format makes the drink more palatable and enjoyable without being overwhelmingly sour. This product specifically combines sea buckthorn juice and blueberry purée (not from concentrate) with other ingredients like sugar to create its characteristic taste profile. Checking the ingredient list on the label will show you the exact components used.
