Dilution & Blending

Water it down to a target, boil it down to a target, mix any number of streams, or split two batches to land exactly on a gravity by Pearson's square. It all rests on one exact fact — properties blend by volume — so gravity, color, bitterness and alcohol come out right together.

Dilute or concentrate

Enter what you have and where you want it. A lower target means water to add; a higher target means water to boil off. If you're diluting finished beer, add the ABV and you'll get the diluted strength too.
