How much caffeine is in Traditional Rye Bread Kvass?

Traditional Rye Bread Kvass is naturally caffeine-free, so each 8 oz cup (240ml) serving contains no measurable caffeine.

What temperature should I use for Traditional Rye Bread Kvass?

Target 22°C (72°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Traditional Rye Bread Kvass be extracted?

Extract for 2-4 days using Jar Fermentation, at a ratio of 100g toasted rye per Liter, prepared at Cracked Grain. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Traditional Rye Bread Kvass taste bitter?

Bitterness almost always indicates over-extraction. Shorten the contact time, lower the water temperature slightly, or use less leaf. Change one variable at a time so you can tell which one was responsible.

Who should avoid Traditional Rye Bread Kvass?

Check acidity, residual sugar, alcohol-by-fermentation risk, and food-safety controls in homemade versions. Use individualized guidance for pregnancy, medication interactions, allergies, reflux, or other health concerns. Do not use a beverage as a replacement for prescribed care; preparation strength can change exposure.
