Oselbirch is a beverage collection offered by the family owned company Oselstuff, and is based in birch water.
Birch water comes from the birch tree and functions as a natural diuretic that can help eliminate toxins from the body. It has "micro-nutrients and vitamins unique to the birch tree," which the brand claims helps to strengthen the immune system, lower cholesterol and assist with weight loss. The Oselbirch drinks are fermented and do not contain any sugar, but has natural flavors like buckthorn, peppermint, sea buckthorn, cranberry and lemon, and lime. The beverages can be consumed on their own or added as an addition to cocktails.
The Oselbirch brand functions as a healthy alternative to the sugary carbonated drinks that are most often purchased by consumers.
