Birch tree sap popularity is increasing and a number of sources point to the numerous health benefits of their consumption. Rarely, however, attention is drawn to the short shelf life of birch tree sap and there are few researches on this subject. In this paper, shelf life of five batches of birch tree sap was evaluated. They were stored at room temperature and in refrigeration. Most favorable parameter for the assessment of changes in birch sap was its turbidity, and to a lesser degree the so-called “optical density” and pH. On the basis of the obtained results, it was found that birch sap at room temperature can be stored for no longer than one day, while in refrigeration of about six days.
