Beer Recipe Scaling Calculator
Scale each recipe ingredient by the ratio of target volume to original recipe volume. This simple method does not compensate for brewhouse efficiency or equipment geometry.

Frequently asked questions
Will the scaled beer have the same gravity?
Only if extraction efficiency and losses stay similar. Smaller equipment and different process geometry can change yield.
Can I scale hop additions this way?
It is a starting point. Bitterness can shift with boil volume, gravity, and utilization.
