If you want to oxygenate wort like the pros do, you can easily make an in-line wort oxygenator. This device ensures uniform and thorough oxygenation of the entire wort. It can be part of a "closed system," which helps ensure good sanitation.This setup also saves the brewer a bit of time; the wort is transferred to the fermentor and oxygenated in one step.

Wort enters through food-grade tubing from the chiller, exits the T at a right angle, and goes to the fermentor. The aeration stone sits in the outlet tube, connected to the oxygen tank by tubing (also food-grade) that passes through the T, and oxygen can be gently bubbled into the wort as it enters the fermentor. This ensures maximum oxygen content of the wort.

This entire assembly can be boiled to sanitize it; the plastic tubing may turn opaque when boiled, but that will not hurt its performance.

Assembly: The diagram serves as a guide to assembling your setup. The parts needed depend on the size of your aeration stone - it must fit into the tubing - and the parts available at your local plumbing supply store. You might need to wrap some Teflon tape around the oxygen tube going into the compression fittings to make a good seal.
