How To Sustainably Achieve And Protect Beer Clarity

By Roland Pahl, Beer Market Manager

Removing turbidity after fermentation and maturation is the first step in achieving beer clarity and stability. Post clarification, colloidal and microbial stabilization are the key steps to achieve a beer in the appealing appearance which makes filtered beer so successful in the market.

Having achieved initial clarity, this however, may not last. Clarified beers must display stability with respect to haze, meaning that the beer must stay bright during the period from dispatch from the brewery to consumption. Beer haze and its chemistry is a complicated matter. A wide range of substances can cause non-biological haze formation (colloidal haze).
