From Beer to Beyond Beer: Filtration Choices That Don’t Always Translate
June, 2026
As brewers expand from traditional beer into no and low alcohol beer and closely related hybrid beverages, many discover that familiar filtration strategies no longer perform as expected. While these segments are sometimes grouped together, it is important to distinguish between NAB and broader Beyond Beer products, as each presents different technical challenges.
Why Aren’t Stability Challenges Always Fermentation Driven in NAB?
In conventional beer, fermentation provides much of the product’s natural stability through alcohol production, pH reduction and predictable yeast removal. In no and low alcohol beer, that safety net is reduced or partially removed, shifting stability control toward cold side processing.
Peer-reviewed studies show that reduced alcohol beers can exhibit greater sensitivity to oxygen driven flavor degradation and microbial instability.
As a result, filtration becomes a primary tool for shelf-life protection rather than just a clarification step.
How Do New Solids Extracts and Flavor Carriers Change Filtration?
In Beyond Beer products, which may include hybrid or functional beverages, ingredient systems can include plant-based extracts, emulsions, and oil-based carriers. These behave differently from traditional brewing solids.
Depth filters designed for beer clarification may load differently when exposed to these materials.
Why Does Botanical Loading Cause Variable Fouling?
Botanical ingredients, when used in Beyond Beer beverages, are inherently variable depending on source, processing and seasonality. This can lead to inconsistent fouling behavior and shorter run lengths.
This variability can impact depth filtration systems used in beer production.
Can Fine Membranes Strip Aroma Compounds?
Fine membrane filtration is an effective microbial control strategy across both NAB and Beyond Beer. However, system optimization is important to preserve aroma and flavor while maintaining protection.
Redefining Clarity and Protection
Some products may intentionally retain haze. However, filtration-based microbial control removes turbidity, meaning clarity and protection must be balanced within process design.

Operational Consequences at Scale
Both NAB and Beyond Beer products can lead to shorter filtration runs, increased fouling and more frequent CIP compared to conventional beer. These effects may be driven by tighter microbial targets in NAB or ingredient variability in Beyond Beer.
Designing Filtration That Fits NAB and Beyond Beer
While NAB may be considered part of the broader Beyond Beer segment, it presents a distinct and dedicated technical challenge. Brewers typically evaluate both categories separately, and filtration strategies should reflect this distinction.
Planning to scale no and low alcohol beer production?
Filtration plays a critical role in protecting flavor stability and ensuring consistent product quality—particularly in NAB, where traditional fermentation safeguards are reduced.
