Ängabackens Björksoda is a new product for Sweden but the drink itself is ancient. The tradition of tapping birch sap is very old in Sweden. However, the knowledge of letting the birch sap ferment into a bubbly, healthy, non-alcoholic drink comes from Eastern Europe.
Birch tapping has always been man's way of utilising the first harvest of the year from nature. Birch sap used to be drunk in the spring when it was considered a very important supplement of vitamins and minerals. The birch was even called the 'poor man's cow' in the old days.
Birch sap consists mostly of the finest water, filtered through the birch's root system and trunk.
It is the other contents of birch sap, including sugars, that allow it to be fermented.
