The Blichmann Engineering Oxygen Flow Regulator helps you dial in the exact liters per minute of oxygen needed to achieve 8-10 ppm of dissolved oxygen in your wort. Having the correct levels of dissolved oxygen in your wort is vital to yeast health and the final flavor profile of your beer. Knowing the flow is important - other regulators simply regulate pressure and depending on your downstream restriction the actual flow can vary widely.
Oxygenation of wort is essential to proper yeast growth and overall health. Healthy yeast has the largest impact over final beer flavor than about any other variable. Achieving 8-10 ppm (parte per million) of dissolved oxygen (DO) in your wort prior to fermentation is vital to achieve your best tasting beer. Too little and yeast growth is stunted and off flavors can be created. Lag times increase and final gravity may not be reached. Too much and and you can end up with excessive fusel alcohols in your finished beer. Blichmann Engineering has done extensive testing to allow you to achieve proper DO levels with wand type and in-line type oxygenation systems so you can be confident you're achieving your DO levels.
