Birch sap is a clear, slightly sweet liquid harvested from birch trees in early spring. It flows as the trees begin to thaw after winter, typically from late March to early April. The sap is collected by drilling small holes into the tree and using tubes or containers to gather the liquid. Rich in nutrients, birch sap contains vitamins, minerals, and antioxidants. It has been consumed for centuries in various cultures, often enjoyed as a refreshing drink or used in traditional remedies. Additionally, it can be processed into birch syrup, similar to maple syrup, offering a unique flavor profile.
