Brewing Application sheet

Attenuation control and light beer production

Novozymes offers a broad range of attenuation control products to allow brewers to manage fluctuations in attenuation and create highly attenuated beers in a simple, cost-effective manner.


● Customized solutions to reach specific attenuation targets and needs
● Manage consumer trends towards low-calorie and light beers
● Opportunity to reach desired maltose to glucose ratios
● Obtain the desired level of fermentable sugars every time


AMG® 300 L BrewQ is a classic glucoamylase for producing highly fermentable glucose-based worts.


The Novozymes range of attenuation enzymes help to break down amylose and amylopectin.

The desired attenuation solution is a choice for the brewery to make. This application sheet focuses on the performance of Attenuzyme® Pro and Attenuzyme® Core, which are the recommended solutions for highly attenuated beer.

Rates of production of fermentable sugars are dose- and time-dependent.

As a rule of thumb, the RDF (real degree of fermentation) correlates with the amount of fermentable sugars * 0.91.

As shown in figure 2, Attenuzyme® Pro is faster at degrading dextrins into fermentable sugars when compared to Attenuzyme® Core due to additional pullulanase activity in Attenuzyme® Pro. The pullulanase works in synergy with malt β-amylase, generating a higher maltose content than Attenuzyme® Core and shortening saccharification times.
