Description
Birch sap can be consumed both raw and cooked, and has a sweet flavor. It is collected in early spring, before the tree's leaves begin to grow. To obtain the sap, a hole approximately 6 mm wide and 4 cm deep is drilled into the trunk. The sap flows best on warm, sunny days after a period of severe frost. The sap can be drunk pure as a refreshing beverage, or it can be concentrated into syrup or sugar. It can even be fermented to make birch beer or vinegar. An old English recipe for brewing birch beer involves mixing birch sap with honey, boiling it with cloves and lime peel, and adding beer for fermentation. The resulting beer is described as mild and safe to consume, increases appetite, and is best drunk before meals.
