Key Benefits Description
  • Achieve desired attenuation

    This product delivers predictable and targeted real degree of fermentation (RDF). It helps you to control the percentage of fermentable sugars you derive from starch. It allows you to increase fermentable sugars or maintain them at a specific level so you can achieve your desired attenuation.

  • Accelerate fermentation

    By releasing more fermentable sugars in the brewhouse, this product supports the need to accelerate your fermentation times.

  • Increase brewhouse capacity

    This fast-acting product shortens mashing times. That allows you to increase brewhouse capacity while saving time and energy. 

Attenuzyme® Clip is a pullulanase that accelerates attenuation. You can use it to get a moderate increase in the attenuation of   maltose-based wort.    

How pullulanase enzymes help control attenuation in brewing

Pullulanases are de-branching enzymes. Brewers use them on their own to achieve small attenuation adjustments via maltose formation. They're also combined with glucoamylases and/or α-amylases to speed up starch breakdown. That allows for shorter conversion times or lower glucoamylase dosage.


Pullulanases are de-branching enzymes. They cleave α-1,6-glucosidic bonds in amylopectin. They're just one of the enzyme classes used to control the degree to which sugars in the wort are fermented into alcohol. Getting attenuation right is about balancing enzyme class, dosage and conversion conditions.

Pullulanases work in synergy with malt β-amylase. That means brewers can use them on their own for small attenuation adjustments via maltose formation. 

Working in combination with glucoamylases and/or α-amylases, pullulanases speed up starch breakdown. Brewers can use these combinations to reach attenuation targets in shorter conversion times. They can also choose to use them to lower glucoamylase dosage.
