Natural food brand Sibberi announced the launch of a new kind of alternative water. An unsweetened Birch water will be available in UK stores and contains only pure birch sap, collected drop by drop from mature silver birch trees. This water hopes to compete with the popularity of other alternative water drinks such as coconut water.
