The birch sap is the juice won from tapping the birch tree. It is also called birch water and can be collected in the first three weeks of spring (after defrost and before the first leaves appear).
The tapping means that one scoops a hollow in the birch bark and sip the juice collected in that or (nowadays through a more up-to-date process) makes a 5-8cm deep hollow, inserts a tube draining out the birch sap. This process does not hurt the three, since only a part of the nutrition comes out and the “wounds” heal automatically.
The birch sap can be consumed fresh as a refreshment or naturally fermented as an alcoolic drink. Sometimes people use it for flavouring wine.
