Birch Sap Kvass with Bread and Honey
A lightly fermented birch sap drink flavored with toasted bread, honey and raisins, kept refrigerated after fermentation.
Birch sap kvass is a lightly fermented drink made by adding toasted bread, honey and raisins to fresh birch sap. Use commercially collected, food-grade sap or sap that has been handled safely, and begin with clean equipment. Warm only part of the liquid to dissolve the honey; high heat can flatten the fresh flavor. Fermentation time depends on temperature, so taste after two days and refrigerate as soon as the drink becomes gently tart and lightly sparkling. This is a small-batch fermented beverage, not a medical tonic and not a shelf-stable canned product. Use the stated measurements, keep the texture cues in view, and let the finished dish cool or rest as directed before serving. This keeps the method practical for a home kitchen and makes the result easier to repeat.
