Beer brewing is a complex process that involves multiple phases and parameters to ensure consistent quality and flavor. From malting and milling the grains to fermenting and conditioning the beer, each step of the brewing process must be carefully monitored and controlled to achieve the desired result. One important parameter to be controlled throughout the process is the turbidity or haze of the beer.

Turbidity provides the consumer’s first visual impression of beer quality. Beer turbidity, technically known as haze, can be a desired or an undesired effect. Industrial beer companies normally choose to filter their beer and follow a precise quality control analysis with the aim of reducing the haze. Consumers expect a filtered beer to be a clear, bright and non-hazy product that remains so during its shelf life. On the other hand, artisanal beers normally have higher haze to maintain their unique flavor and appearance, specially for some types of beers such as New-England Indian Pale Ale (NEIPA).
