Oxygenation Rate Calculator

How much flow and how long to hit your target dissolved oxygen. The solid part is the ceiling: at your temperature and gravity there is a hard limit on what air can reach, and this tells you when you need pure oxygen instead. The run-time is an honest best guess anchored to published bench data, not your exact rig, so treat it as a starting point and let one DO reading from your own setup sharpen it.

Your wort

Wort volume

Original gravity

Higher gravity holds less oxygen.

Wort temperature (at the moment you oxygenate)

Colder wort holds more oxygen. Oxygenate before it warms.

How you are adding it

Gas

Method

Gas flow rate

Stone porosity

Finer means smaller bubbles, faster transfer, less oxygen lost to the headspace.

Wort depth (relative to a typical bucket)

A taller column gives bubbles a longer rise, so a little more dissolves. A rule-of-thumb nudge, not a precise term.

Headspace

Your target

Target dissolved oxygen

Custom target (ppm)

Calibrate to your rig (optional, makes the estimate much tighter)

Measured dissolved oxygen just once on your own setup? Enter that reading and the tool stops guessing your transfer rate and uses yours. This only applies to metered stone or tubing methods.

Measured DO you reached (ppm)

Run time for that reading (seconds)

Flow you used (same units as above)
