Collecting birch sap should be done exclusively in ecologically clean places away from cities and roads. Choose birch that is not thinner than 20 cm in diameter and do not take more than one and a half to 2 liters of birch sap from one tree so as not to harm nature. The most useful and delicious birch sap is collected in a mixed forest. Then, in addition to birch, other deciduous trees grow. Birch sap is collected in the morning in sunny weather. The juice flows poorly or does not flow at all in the evening or in bad weather. The sap inside the birch circulates between the bark and the base of the tree. So there is no point in cutting wood deep. On the south side of the tree at a height of 40-60 cm, pierce the bark with a drill or a special knife blade. Clean the hole and wait for the juice to appear. Insert an aluminum or plastic groove under the hole in the bark at a 45-degree angle. The groove should be in the shape of the Latin letter V in which birch sap will flow. You can collect the juice in a plastic or glass container. Canned birch sap can be prepared by heating to 80 degrees. Then pour the juice into glass and sterilized jars. Store in a cool, dry place. Birch sap concentrate was obtained by evaporation. The juice is heated to 65-70 degrees until 50% of the volume evaporates. Dilute with water before use. Frozen birch sap retains all the useful substances and properties, You can freeze it in ice buckets or plastic bottles. It can be stored in freezer bags.
