Dextrose Dosing Calculator™

How much dextrose you can add to a beer, and what it does to gravity, ABV, and temperature. Built for the brewhouse but scalable to homebrew — be careful, a hot sugar solution holds a lot of energy.

The addition

Water temperature (used to dissolve the dextrose)

Dextrose to add (mass of dry sugar)

Beer volume (what the solution goes into)

Beer temperature (before the addition)

Pick a unit on the right of any field and the numbers convert in place — your inputs and results follow whatever system you prefer.

ABV added

—

— SG added to the beer

Solubility exceeded. At this water temperature the dextrose won't fully dissolve. Raise the water temperature or reduce the amount of dextrose.

Dextrose solution

Final beer

ABV added is the approximate alcohol increase once the added sugar fully ferments out. A hot, concentrated sugar solution carries a lot of heat and energy — add it carefully and watch the temperature rise on your batch.
