Wash the sea buckthorn berries and pour them into a large bowl.

Using a potato masher or blender, chop the berries until smooth.

Pass the mixture through a fine or medium sieve, removing any small seeds and pulp.

Now add sugar or your favorite sweetener to the concentrated sea buckthorn juice and mix well.

Pour the delicious sea buckthorn juice into beautiful glasses and add the filtered water.

Serve cold with a sprig of mint. If desired, you can add a few whole sea buckthorn berries to the glass.
