Fermented birch sap, BIO, 6l or 12l

We have noticed that a large portion of our birch sap customers fall into two teams - those who only like very fresh and clear sap collected at the beginning of the sap season, and those who wait a bit and send their sap at the end of the sap season, because it can easily sour later.
That's why we have created a new product - Fermented birch sap , which will be available for purchase all year round!
