We got to try Säpp Birch Water, which claims to be detoxifying and organic — harvested directly from birch trees and never diluted with water. Säpp has no added sugars and only contains 10 calories per bottle.
The unflavored variety garnered a mixed review, some finding it "super refreshing" and others finding it to taste "like watered down leftover kombucha foam" (oddly specific). Most noted a tart or sour taste, despite it being very mild.
Also particularly tart was the nettle flavor, which was very well received. Most who tested it said it "tastes like lemon iced tea" and said it was quite refreshing. Another kombucha reference came up (must be the sour flavor): "tastes like kombucha, but not fizzy." One confused commenter said "Good. Tastes like old stale wine." We have no idea what that means.
With a distinct molasses smell, the rosehip flavor was the sweetest of all the flavors, with a bit of tartness true to all three birch waters. One taste tester described "floral notes; tart but elegant," while another said "tastes like sour plum juice (good thing)." Another reference to tea was made, but it was described as watered down: "like tea I let my ice melt in. Not bad."
