Birch sap tapping is an ancient tradition in Finland. There are many Finnish folk tales about the extraction of birch sap and it is believed to have medicinal properties. At exactly the right moment at the beginning of spring, a small hole is drilled into the tree trunk and this natural nutritious clear liquid flows out.

The sap has been used locally and traditionally by people in Finland for centuries. However, small companies are now realising the added value that the production of birch sap can have alongside birch wood production. New techniques have been developed for collecting the sap, and the demand for the sap is growing on export markets.
