ROOTED IN THE BIRCH FOREST

From Forest to Bottle

Each spring, we harvest wild Alaska birch sap using low-impact tapping methods, then transform it through fermentation, concentration and small-batch craft.

Our Approach

Every product begins with the birch forest. We harvest sap during Alaska’s brief spring thaw using low-impact tapping methods designed with long-term forest health in mind, then transform that harvest through fermentation, concentration, and small-batch craft.
