The Importance of Dissolved Oxygen Sensors in Brewing and Beverage Manufacturing

Dissolved oxygen (DO) measurements are required throughout the beer brewing process. In the initial stages of the fermentation process, yeast needs high oxygen levels to maintain metabolism. In the later stages of fermentation, oxygen levels decrease as alcohol and CO2 increase.

Downstream from the fermentation process, oxygen measurement serves as a quality control check. Excess oxygen in the finished product decreases the shelf life and stability of the beer – thus degrading its taste and color.

Sensors employed in brewery operations face challenging conditions. They need to endure regular chemical cleaning and disinfection after every batch. The sensor may also be exposed to solids (such as hops and grains).
