Beginner Tips
- •Scale grain and hops linearly for small changes.
- •Re-check your IBUs after scaling since utilization shifts with gravity.
- •Yeast pitch rate should scale with volume and gravity, not linearly alone.
Common Mistakes
- •Scaling water without re-checking mash thickness.
- •Forgetting to recalculate hop utilization for larger boils.
- •Assuming efficiency stays identical across batch sizes.
