Ask Mr. Wizard

Oxygen Quality


Sam Schalley - Rochester, Minnesota asks,

To follow up on your comments in the September 2014 issue on Food-Grade CO2; what about food-grade oxygen? I get bottled oxygen from my local welding shop, to aerate wort, and have always pondered the quality of it.


The Wiz answers questions about oxygen quality, not removing the trub and recipe formulation.
