Every year in early spring, before trees produce new leaves, birch trees provide a unique gift - birch juice. Birch sap, also know as birch water or 'kasemahl' (in Estonian), is a clear, slightly sweet and nutrient-rich detoxifying liquid that has a very limited harvesting period. The ideal time to extract birch juice in Estonia is between late February and mid-April when temperatures rise above freezing during the day and drop below zero at night. If you harvest birch juice after this time, the sap will be noticeably cloudier and bitter.
Estonians have collected birch sap in the forest for centuries. It's a traditional springtime tonic, consumed after winter to cleanse the body, boost immunity, and provide essential vitamins and minerals.
What are the health benefits of birch juice?
Birch juice is widely considered a "youth elixir" as it's packed with minerals (magnesium, potassium calcium), antioxidants and vitamin C. The amino acids present in the birch sap support bone health, reduce oxidative stress, and aid detoxification. Often consumed for its anti-inflammatory properties, birch juice supports kidney function, promotes digestion, and is a great hydrating agent for skin elasticity. It's Mother Nature's medicine in its purest form, teeming with every imaginable vitamin and mineral.
