Our Raspberry Birch Brew starts with raw, certified organic birch sap, wild-harvested from Alaska’s boreal forests and fermented in small batches using our traditional double-fermentation process. Organic raspberry purée adds a bright, tart berry character that pairs naturally with Birch Brew’s crisp, dry, and refreshing finish. Wild fermented. Zero sugar. Billions of living cultures. Never pasteurized. 11.2 fl oz bottle.
