What You Need to Know
Kvass is traditionally made from water, yeast, sugar, rye bread, and raisins. The presence of sugar and rye bread makes it incompatible with a ketogenic diet, which requires very low carbohydrate intake to maintain ketosis. The fermentation process may reduce some sugars, but the overall carbohydrate content remains too high for those adhering to strict keto guidelines.
