Scaling Factor

• Ratio maintained: 1:15.0

• Time scaled by √factor for extraction

⚠ Large scaling - monitor extraction carefully

Time scales by square root to maintain proper extraction

For large batches (5x+), consider bloom time adjustments

Equipment size may limit maximum scaling factor

Small batches may need slightly finer grind
